HOW TO USE THIS MANUAL B

This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.

The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)

When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Points section). See the System Outline to understand the circuitoperation.

When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors, splice points, and ground points of eachsystem circuit. Internal wiring for each junction block is also provided for betterunderstanding of connection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.

STOP LIGHT DISCONNECTION WARNINGWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

1. HEATER BLOWER OPERATIONManual operationWhen the blower speed is set to a certain level using the blower control SW, the A/C control assembly sends the signals tothe blower control to control the blower motor speed.Auto operationWhen the auto SW is turned on, the A/C control assembly sends the signals from various sensors and temperature SW tothe blower control to automatically control the blower motor speed.

2. AIR INLET CONTROL SERVO MOTOR CONTROLWhen the FRESH/RECIRC select SW is set to RECIRC, the motor in the air inlet control servo motor starts rotating to movethe damper toward the RECIRC side. Since the damper position is detected by the TERMINAL TP1 of the A/C controlassembly, the motor is continuously rotated until the damper reaches its stop position.When the FRESH/RECIRC select SWis set to FRESH, the motor in the air inlet control servo motor starts rotating to move the damper toward the FRESH side.Since the damper position is detected by the TERMINAL TP1 of the A/C control assembly, the motor is continuously rotateduntil the damper reaches its stop position.When the FRESH/RECIRC select SW is set to AUTO, the exhaust gas sensorinstalled in the engine room monitors contents in the exhaust gas and FRESH or RECIRC is automatically switched.

3. AIR VENT MODE CONTROL SERVO MOTOR CONTROLWhen the mode select SW is pushed, the ECU in the A/C control assembly activates the air vent mode control servo motor.This causes the servo motor to rotate to the position (FACE, BI–LEVEL, FOOT, FOOT/DEF, DEF) selected using the modeselect SW, and moves the film damper.

4. AIR MIX CONTROL SERVO MOTOR CONTROLWhen the temperature control SW on the driver’s side is pressed, the ECU in the A/C control assembly sends a signal to theair mix control servo motor on the driver’s side. This signal drives the motor to reach the temperature set by the temperaturecontrol SW on the driver’s side, and moves the film damper. Passenger’s side is operated as same as the driver’s side.

5. AIR CONDITIONING OPERATIONThe A/C control assembly receives various signals, I.E., the engine RPM from the crankshaft position sensor, outlettemperature signal from the A/C ambient temp. sensor, coolant temperature from the engine coolant temp. sensor and thelock signal from the A/C compressor, etc. When the engine is started and the A/C SW is on, a signal is input to the ECU(Built into the A/C control assembly). As a result, the ground circuit in A/C control assembly is closed and current flows fromHEATER fuse to TERMINAL 1 of the A/C COMP relay to TERMINAL 2 to TERMINAL ACMG of the engine control module toTERMINAL MPX2 to TERMINAL MPX+ of the A/C control assembly to TERMINAL GND to GROUND, turning the relay onso that the A/C magnetic clutch is on and the A/C compressor operates. At the same time, the engine control module detectsthe magnetic clutch is on and the A/C compressor operates and rotates the motor to the open direction to avoid lowering theengine RPM during A/C operation. When any of the following signals are input to the A/C control assembly, the controlassembly operates to turn off the air conditioning.∗ Coolant temp. signal is high.∗ A signal that the temperature at the air outlet is low.∗ A signal that there is a large difference between engine speed and compressor speed.∗ A signal that the refrigerant pressure is abnormally high or low.

A4 A/C DUAL PRESSURE SW1–4 : Open with the refrigerant pressure at less than approx. 216 kpa (2.2 kgf/cm2, 31 psi) or more than

approx. 3138 kpa (32 kgf/cm2, 455 psi)

AUTOMATIC LIGHT CONTROL

When the light control SW is set at AUTO, the automatic light control system automatically turns on or off the taillights andheadlights depending on the brightness around the vehicle.

AUTOMATIC LIGHT CONTROL OPERATIONThe automatic light control sensor converts the intensity of the illumination into frequency and inputs it to the body ECUNo.2. When the light control SW is set at AUTO, the signal is input to TERMINAL AUTO of the body ECU No.2. Throughcommunication control of the body ECU and door ECU etc. , the taillights and headlights are automatically turned on or off.Turn on operationWhen the body ECU No.2 receives the frequency signal from the automatic light control sensor and determines that thebrightness around the vehicle has decreased below a specified level, TERMINAL TRLY and HRLY of the body ECU No.2are controlled through communication control of the body ECU and door ECU etc. As a result, the taillights and headlightslight up as the TAIL relay and HEAD LP relay are turned on.Turn off operationWhen the body ECU No.2 receives the frequency signal from the automatic light control sensor and determines that thebrightness around the vehicle has exceeded a specified level, TERMINAL TRLY and HRLY of the body ECU No.2 arecontrolled through communication control of the body ECU and door ECU etc. As a result, the taillights and headlights go offas the TAIL relay and HEAD LP relay are turned off.Additionally, when the ignition SW is changed from ON to OFF and any door is opened, and then closed with the taillightsand headlights lit (The automatic light control is functioning), the taillights and headlights are turned off in the same manneras the light auto turn off operation.

The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makesit possible to automatically adjust the opening of the engine throttle valve without depressing of the accel. pedal.

1. SET OPERATIONWhen the cruise control main SW is turned on, the system starts preparations necessary for the cruise control and turns onthe indicator light in the combination meter.

2. SET SPEED CONTROLWhen the SET/COAST SW is operated with the cruise control main SW turned on during travelling, the constant vehiclespeed is controlled.

3. COAST CONTROLWhen the SET/COAST SW is kept turned on during cruise control travelling, the engine control module controls the throttlevalve to decelerate the vehicle. Every time the SET/COAST SW is turned on instantaneously, the vehicle speed isdecelerated approximately 1.5 km/h.

4. ACCEL CONTROLWhen the RES/ACC SW is kept turned on during cruise control travelling, the engine control module controls the throttlevalve to accelerate the vehicle. Every time the RES/ACC SW is turned on instantaneously, the vehicle speed is acceleratedapproximately 1.5 km/h.

5. RESUME CONTROLWhen the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, useof the RES/ACC SW accelerates the vehicle to the speed level used before canceling the cruise control.

6. MANUAL CANCEL MECHANISMIf any of the following signals is input during cruise control travelling, the cruise control is cancelled.∗ The stop light SW is turned on.∗ The CANCEL SW is turned on.∗ The cruise control main SW is turned off.∗ The VSC is activated.

7. AUTO CANCEL FUNCTIONIf any of the following conditions is encountered, the cruise control is automatically cancelled.∗ The stop light SW wiring is faulty or short–circuited.∗ The vehicle speed signal is faulty.∗ The electronically controlled throttle malfunctions.

8. OVERDRIVE CONTROL FUNCTIONThe overdrive control may be cancelled if the vehicle travels on the slope during cruise control travelling. After the overdrivecontrol has been cancelled, if the vehicle speed exceeds the overdrive return speed (The set speed is 2 km/h, 1.2 mph) andit is decided that the slope is finished, the vehicle returns to the overdrive control mode again.

The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makesit possible to automatically adjust the opening of the engine throttle valve without depressing of the accel. pedal.

1. SET OPERATIONWhen the cruise control main SW is turned on, the system starts preparations necessary for the cruise control and turns onthe indicator light in the combination meter.

2. SET SPEED CONTROLWhen the SET/COAST SW is operated with the cruise control main SW turned on during travelling, the constant vehiclespeed is controlled.

3. COAST CONTROLWhen the SET/COAST SW is kept turned on during cruise control travelling, the engine control module controls the throttlevalve to decelerate the vehicle. Every time the SET/COAST SW is turned on instantaneously, the vehicle speed isdecelerated approximately 1.5 km/h.

4. ACCEL CONTROLWhen the RES/ACC SW is kept turned on during cruise control travelling, the engine control module controls the throttlevalve to accelerate the vehicle. Every time the RES/ACC SW is turned on instantaneously, the vehicle speed is acceleratedapproximately 1.5 km/h.

5. RESUME CONTROLWhen the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, useof the RES/ACC SW accelerates the vehicle to the speed level used before canceling the cruise control.

6. MANUAL CANCEL MECHANISMIf any of the following signals is input during cruise control travelling, the cruise control is cancelled.∗ The stop light SW is turned on.∗ The CANCEL SW is turned on.∗ The cruise control main SW is turned off.∗ The VSC is activated.

7. AUTO CANCEL FUNCTIONIf any of the following conditions is encountered, the cruise control is automatically cancelled.∗ The stop light SW wiring is faulty or short–circuited.∗ The vehicle speed signal is faulty.∗ The electronically controlled throttle malfunctions.

8. OVERDRIVE CONTROL FUNCTIONThe overdrive control may be cancelled if the vehicle travels on the slope during cruise control travelling. After the overdrivecontrol has been cancelled, if the vehicle speed exceeds the overdrive return speed (The set speed is 2 km/h, 1.2 mph) andit is decided that the slope is finished, the vehicle returns to the overdrive control mode again.

Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, electricallycontrols the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. Theelectronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response tothe vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible byshift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,squat and gear shift shock when starting off.

1. GEAR SHIFT OPERATIONWhen driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine control module from theengine coolant temp. sensor and the vehicle speed signal from vehicle speed sensor is input to TERMINAL SP2+ of theengine control module. At the same time, the throttle valve opening signal from the throttle position sensor is input toTERMINALS VTA and VTA2 of the engine control module as throttle angle signal.Based on these signals, the engine control module selects the best shift position for the driving conditions and sends currentto the electronically controlled transmission solenoid.

2. LOCK–UP OPERATIONWhen the engine control module decides based on each signal that the lock–up condition has been met, the current flowsthrough TERMINAL SLU+ of the engine control module to TERMINAL 4 of the electronically controlled transmission solenoidto TERMINAL 10 to TERMINAL SLU– of the engine control module to GROUND.

3. STOP LIGHT SW CIRCUITIf the brake pedal is depressed (Stop light SW on) when driving in lock–up condition, a signal is input to TERMINAL STP ofthe engine control module. The engine control module operates and cuts the current to the solenoid to release lock–up.

4. ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW CIRCUITWhen the electronically controlled transmission pattern select SW is switched to PWR, a signal is input to TERMINAL PWRof the body ECU No.1, and control signals are distributed to the engine control module through communication control of thebody ECU. This enables shift–up and shift–down at a higher speed range.

5. E–SHIFT SYSTEMWhen the shift lever is set to the M position, the shift range can be switched with the UP or DOWN switch on the steering.(This limits to the maximum gear step and enables automatic shift–up and shift–down within the allowable range.)

This system utilizes an engine control module and maintains overall control of the engine, transmission and so on. An outlineof the engine control is explained here.

1. INPUT SIGNALS(1) Engine coolant temp. signal circuit

The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.

(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal to TERMINAL THA of the engine control module.

(3) Oxygen sensor signal circuitThe oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensors(Bank 1 sensor 1, bank 2 sensor 1, bank 1 sensor 2 and bank 2 sensor 2) to TERMINALS OXL1, OXR1, OXL2 andOXR2 of the engine control module.To stabilize detection performance by the heated oxygen sensors, the heated oxygen sensors are warmed. This heateris also controlled by the engine control module (HTL, HTR, HTL2 and HTR2).

(4) RPM signal circuitCamshaft position is detected by the camshaft position sensor and its signal is input to TERMINAL G2 of the enginecontrol module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor installed in thecylinder block and the signal is input into TERMINAL NE+ of the engine control module as a control signal.

(5) Throttle signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALSVTA and VTA2 of the engine control module.

(6) Vehicle speed circuitSignals detected by ABS speed sensors are input into the combination meter through ABS & TRAC & VSC ECU. Then itis delivered to the engine ECU through MPX communication.

(7) A/C SW signal circuitThe operating voltage of the A/C magnetic clutch is detected and the signal is input into TERMINAL ACMG of the enginecontrol module as a control signal.

(8) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. With the ignition SW turned on, Voltagefor engine control module start–up power supply is applied to TERMINALS +B and +B1 of the engine control module viathe EFI relay.The current flowing through the IGN fuse to TERMINAL IGSW of the engine control module.Voltage is constantly applied to TERMINAL +BM of the engine control module.

(9) Intake air volume signal circuitIntake air volume is detected by the mass air flow meter and the signal is input to TERMINAL VG of the engine controlmodule as a control signal.

(10)Stop light SW signal circuitThe stop light SW is used to detect whether or not the vehicle is braking and the signal is input into TERMINAL STP ofthe engine control module as a control signal.

(11) Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor during cranking is detected and thesignal is input into TERMINAL STA of the engine control module as a control signal.

(12)Engine knock signal circuitEngine knocking is detected by knock sensor 1 and 2 and the signal is input into TERMINALS KNKL and KNKR as acontrol signal.

SYSTEM OUTLINE

2. CONTROL SYSTEM∗ SFI system

The SFI system monitors the engine condition through the signals input from each sensor (Input signals from (1) to (12)etc.) to the engine control module. The best fuel injection timing is decided based on this data and the programmemorized by the engine control module, and the control signal is output to TERMINALS #10, #20, #30, #40, #50, #60,#70 and #80 of the engine control module to operate the injector (Inject the fuel). The sequential multiport fuel injection(Electronic fuel injection) system controls the fuel injection operation by the engine control module in response to thedriving conditions.

∗ ESA (Electronic Spark Advance) systemThe ESA system monitors the engine condition through the signals input to the engine control module from each sensor(Input signals from (1), (2), (4) to (12) etc.). The best ignition timing is decided according to this data and the memorizeddata in the engine control module, and the control signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6,IGT7 and IGT8. This signal controls the igniter to provide the best ignition timing for the driving conditions.

∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. ofexhaust emissions is low), and warms up the heated oxygen sensors (Bank 1 sensor 1, bank 2 sensor 1, bank 1 sensor2 and bank 2 sensor 2) to improve detection performance of the sensors.The engine control module evaluates the signals from each sensor (Input signals from (1), (2), (4), (8) to (10) etc.), andoutputs current to TERMINALS HTL, HTR, HTL2 and HTR2 to control the heater.

∗ ACISACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed inaccordance with the driving conditions to control the intake manifold length in two stages for increased engine output inall ranges from low to high speeds.The engine control module judges the engine speed by the signals ( (4), (5) ) from each sensor and outputs signals tothe TERMINAL ACIS to control the VSV (ACIS).

∗ Fuel pump controlThe engine control module outputs current to TERMINAL FPC and controls the fuel pump control ECU and fuel pumpdrive speed in response to driving conditions.

∗ ETCS–iThe ETCS–i controls the engine output at its optimal level corresponding to the opening of the accel. pedal under alldriving conditions.

∗ MPXThe MPX communicates with the combination meter, A/C control assembly, as well as body ECU of the multiplexcommunication system

3. DIAGNOSIS SYSTEMWith the diagnosis system, when there is a malfunction in the engine control module signal system, the malfunctioningsystem is recorded in the memory. The malfunctioning system can be found by reading the code displayed by themalfunction indicator lamp.

4. FAIL–SAFE SYSTEMWhen a malfunction has occurred in any system, if there is a possibility of engine trouble being caused by continued controlbased on the signals from that system, the fail–safe system either controls the system by using data (Standard values)recorded in the engine control module memory or else stops the engine.

TACHOMETER

The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outlineof the engine control is given here.

1. INPUT SIGNALS(1) Engine coolant temp. signal circuit

The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermister with a resistance, whichvaries according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the enginecontrol module as a control signal.

(2) Intake air temp. signal circuitThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp. which is input as acontrol signal to TERMINAL THA of the engine control module.

(3) Oxygen density signal circuitThe oxygen density in the exhaust emission is detected by the heated oxygen sensors and input as a control signal toTERMINALS OX1A, OX2A, OX1B and OX2B of the engine control module.

(4) RPM signal circuitCamshaft position is detected by the camshaft position sensor and its signal is input to TERMINAL G2 of the enginecontrol module as a control signal.Also,engine RPM is detected by the crankshaft position sensor and is input as a control signal to TERMINAL NE+.

(5) Throttle position signal circuitThe throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALVTA of the engine control module.

(6) Vehicle speed circuitThe vehicle speed sensor (Electronically controlled transmission) detects the vehicle speed and inputs a control signalto TERMINAL SP2+ of the engine control module.

(7) Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine control module. With the ignition SW turned on, thevoltage for engine control module start–up power supply is applied to TERMINALS +B, B2 of the engine control modulevia the EFI relay.The current flowing through the IGN fuse flows to TERMINAL IGSW of the engine control module.Voltage is constantly applied to TERMINAL BM of the engine control module.

(8) Intake air volume signal circuitIntake air volume is detected by the mass air flow meter and the signal is input to TERMINAL VG of the engine controlmodule as a control signal.

(9) Stop light SW signal circuitThe stop light SW is used to detect whether the vehicle is braking or not and the signal is input into TERMINAL STP ofthe engine control module as a control signal.

(10)Starter signal circuitTo confirm whether the engine is cranking, the voltage is applied to the starter motor during cranking is detected and thesignal is input into TERMINAL STA of the engine control module as a control signal.

(11) Engine knock signal circuitEngine knocking is detected by knock sensors and the signal is input into TERMINALS KNK1 and KNK2 as a controlsignal.

SYSTEM OUTLINE


2. CONTROL SYSTEM∗ SFI system

The SFI system monitors the engine condition through the signals input from each sensor (Input signals from (1) to (11)etc.) to the engine control module. And the control signal is output to TERMINALS #10, #20, #30, #40, #50 and #60 ofthe engine control module to operate the injector (Inject the fuel). The SFI system controls the fuel injection operation bythe engine control module in response to the driving conditions.

∗ ESA systemThe ESA system monitors the engine condition through the signals input to the engine control module from each sensor(Input signals from (1), (2), (4), to (11) etc.). The best ignition timing is decided according to this data and the memorizeddata in the engine control module and the control signal is output to TERMINALS IGT, IGT2, IGT3. This signal controlsthe igniter to provide the best ignition timing for the driving conditions.

∗ Heated oxygen sensor heater control systemThe heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. ofexhaust emissions is low), and warms up the oxygen sensors to improve detection performance of the sensors. Theengine control module evaluates the signals from each sensor (Input signals from (1), (2), (4), (7), to (9) etc.), andoutputs current to TERMINALS HT1A, HT2A, HT1B and HT2B to control the heater.

∗ Fuel pump control systemThe engine control module outputs current to TERMINAL FPC and controls the fuel pump control ECU and fuel pumpdrive speed in response to the driving conditions.

∗ ACISACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed inaccordance with the driving conditions to control the intake manifold length in two stages for increased engine output inall ranges from low to high speeds.

∗ ETCS–iThe ETCS–i controls the engine output at its optimal level corresponding to the opening of the accel. pedal under alldriving conditions.

∗ MPXThe MPX communicates with the combination meter, A/C control assembly, as well as body ECU of the multiplexcommunication system

3. DIAGNOSIS SYSTEMWith the diagnosis system, when there is a malfunction in the engine control module signal system, the malfunctioningsystem is recorded in the memory. The malfunctioning system can be found by reading the code displayed by themalfunction indicator lamp.

4. FAIL–SAFE SYSTEMWhen a malfunction has occurred in any system, if there is a possibility of engine trouble being caused by continued controlbased on the signals from that system, the fail–safe system either controls the system by using data (Standard values)recorded in the engine control module memory or else stops the engine.

1. DAYTIME RUNNING LIGHT OPERATIONWhen the engine is started, the generator signal is input from the body ECU No.2 to TERMINAL 5 of the daytime runninglight relay (Main). At this time, when the parking brake pedal is depressed (The parking brake SW is on), the relay is notactivated and the daytime running light system does not function. When the parking brake pedal is released (The parkingbrake SW is off), the signal is input to TERMINAL 4 of the daytime running light relay (Main). This activates the relay to turnon the DIMMER DRL NO.2 relay. The current flows from the battery into the MAIN fuse to DRL NO.2 fuse to DIMMER DRLNO.2 relay (Point side) to H–LP L UPR fuse to TERMINAL 2 of the headlight LH (High) to TERMINAL 1 to TERMINAL 1 ofthe headlight RH (High) to TERMINAL 2 to TERMINAL (A) 5 of the daytime running light relay No.3 to TERMINAL (A) 3 toTERMINAL 1 of the daytime running light resistor (USA) or short connector (Canada) to TERMINAL 2 to GROUND. Theheadlights light up more dimly than usual as the engine is started.Once the daytime running light system has been activated, the headlights are remained lit even though the parking brakepedal is depressed (The parking brake SW is on). Even if the engine is stopped and the generator signal is cut off with theignition SW set at ON, the headlights are remained lit. When the ignition SW is turned from ON to OFF, the daytime runninglight system is stopped and the headlights go off. If the engine is started with the parking brake pedal released, the daytimerunning light system starts functioning and the headlights light up as the engine is started.

2. HEADLIGHT OPERATION∗ Light control SW is set at HEAD.

When the light control SW is set to HEAD position, the signal is input to TERMINAL 15 of the body ECU No.2. Thisactivates the body ECU No.2 and turns on the HEAD LP relay. When the signal is input to TERMINAL 2 of the daytimerunning light relay (Main), the daytime running light system is deactivated and headlights LH and RH (High) go off. Atthis time, the current flows from the battery into the MAIN fuse to HEAD LP relay (Point side) to H–LP L LWR and H–LPR LWR fuse to TERMINAL 1 of the headlights LH and RH (Low) (except HID type) or TERMINAL 2 of the HEADLIGHTCONTROL ECU LH and RH (HID type) to TERMINAL 2 (except HID type) or TERMINAL 1 (HID type) to GROUND, toturn on the headlights (Low beam).

∗ Dimmer SW is set at HIGH.When the light control SW is set to HEAD position, the current flows into the daytime running light relay No.3 and No.4(Coil side) to turn on the relay as the headlights (Low beam) light up. At this time, when the dimmer SW is set to HIGHposition, the signal is input to TERMINAL 8 of the daytime running light relay (Main). This activates the DIMMER DRLNO.2 relay to flow the current from the battery into the MAIN fuse to DRL NO.2 fuse to DIMMER DRL NO.2 relay (Pointside) to headlights LH and RH (High) to daytime running light relay No.4 (Point side) to GROUND, to turn on theheadlights (High and low) and high beam indicator light at the same time.

∗ Dimmer SW is set at FLASH.When the dimmer SW is set to FLASH position, the current flows from the battery into the MAIN fuse, HEAD LP relay(Coil side) to TERMINAL 9 of the combination SW to TERMINAL 17 to GROUND in that order to turn on the HEAD LPrelay.Additionally, the signal is input to TERMINAL 8 of the daytime running light relay (Main) to activate the relay and turn onthe DIMMER DRL NO.2 relay. In the same manner as the dimmer SW set at HIGH position, the headlights (High andlow) and high beam indicator light are turned on at the same time.

HEADLIGHT BEAM LEVEL CONTROL

This system calculates changes in the illuminating angle from changes in the vehicle height and axle distance based on theinformation on the vehicle height detected by the height sensors installed at the front and rear of the vehicle and informationon the vehicle speed and acceleration output from the VSC system to reversely operate the reflector by the obtainedilluminating angle through actuators in order to always keep the beam axis constant.If an error occurs in this system, the headlight beam level control warning light in the combination meter lights up to warn thedriver.

H1 (A), H2 (B) HEADLIGHT BEAM LEVEL CONTROL ECU(A) 1, (B) 8–GROUND : Approx. 12 volts with ignition SW at ON or ST position(A) 4–GROUND : Always continuity(B) 4–GROUND : Approx. 12 volts with light control SW at HEAD position

1. SEAT BELT WARNING SYSTEMWhen the ignition SW is turned to the ON position, the signal is input to the body ECU and door ECU. At this time, todetermine whether or not the driver fastens the seat belt, the signal from the buckle SW LH is input to TERMINAL DBKL ofthe body ECU No.2. If the driver does not fasten the seat belt, the seat belt warning light in the combination meter flashesand the alarm buzzer goes on, in response to the communication control of the body ECU and door ECU etc.Additionally, the sensor (Seat belt warning occupant detection sensor) installed on the front passenger seat detects thepassenger and determines whether or not the passenger fastens the seat belt.If the passenger does not fasten the seat belt, the signals from the seat sensor and buckle SW RH are input to TERMINALPBKL of the body ECU No.1 and through communication control of the body ECU and door ECU etc. the passenger seatbelt warning light in the clock is flashed.

2. KEY REMINDER SYSTEMIf the driver door is opened with the ignition SW set at the ACC or OFF position and the ignition key remained inserted intothe key cylinder (The unlock warning SW is on), the signal from the unlock warning SW is input to TERMINAL KSW of thebody ECU No.2 and the signal from the door courtesy SW front LH is input to TERMINAL CTY of driver door ECU. As aresult, through communication control of the body ECU and door ECU etc. the buzzer in the combination meter goes on towarn the driver that the ignition key is still inserted.

MOON ROOF

In this system, the HALL IC in the moon roof control ECU detects changes in the motor rotation to allow opening/closing andtilting up/down of the moon roof using one touch operation. Additionally, catching prevention mechanism during moon roofoperation is also provided.

Voltage is always applied from the S/ROOF fuse to TERMINAL 5 of the moon roof control ECU. When the ignition SW isturned to ON, the voltage is applied from the EUG–IG fuse to TERMINAL 8 of the moon roof control ECU.

1. SLIDE OPEN OPERATIONWhen the moon roof control SW is kept pressed to OPEN position for approximately 0.3 sec. or longer (The limit SW No.1 isoff and limit SW No.2 is on), the signal is input from TERMINAL 1 of the moon roof control SW to TERMINAL 9 of the moonroof control ECU. This activates the ECU and rotates the motor to open the moon roof. After that, when the limit SW No.1 isturned on, and then turned off again, the pulse signal sent from the HALL IC activates the ECU, and it determines that themoon roof is fully opened, and stops the motor rotation. If other operation SW or open SW is operated while the moon roof isbeing opened, the ECU is activated to stop the moon roof operation. Additionally, when the moon roof is tilted up, the slideopen operation does not function.

2. SLIDE CLOSE OPERATIONWhen the moon roof control SW is kept pressed to CLOSE position for approximately 0.3 sec. or longer (The limit SW No.1is off and limit SW No.2 is off), the signal is input from TERMINAL 4 of the moon roof control SW to TERMINAL 10 of themoon roof control ECU. This activates the ECU and rotates the motor to automatically close the moon roof. After that, whenthe limit SW No.2 is turned on, the pulse signal sent from the HALL IC activates the ECU, and it determines that the moonroof is fully closed, and stops the motor rotation. If other operation SW or close SW is operated while the moon roof is beingclosed, the ECU is activated to stop the moon roof operation.

3. TILT UP OPERATIONWhen the moon roof control SW is kept pressed to TILT UP position for approximately 0.3 sec. or longer (The limit SW No.1is off and limit SW No.2 is on), the signal is input from TERMINAL 3 of the moon roof control SW to TERMINAL 4 of themoon roof control ECU. This activates the ECU and rotates the motor to automatically tilt up the moon roof. If the pulsesignal sent from the HALL IC is not input for 0.5 sec. or longer when the moon roof is fully tilted up, the ECU determines thatthe motor has stopped, and stops the current flowing into the motor.If other operation SW or tilt up SW is operated while the moon roof is being tilted up, the ECU is activated to stop the moonroof operation. Additionally, when the moon roof is open, the tilt up operation does not function.

4. TILT DOWN OPERATIONWhen the moon roof control SW is kept pressed to TILT DOWN position for approximately 0.3 sec. or longer (The limit SWNo.1 is on and limit SW No.2 is on), the signal is input from TERMINAL 2 of the moon roof control SW to TERMINAL 3 of themoon roof control ECU. This activates the ECU and rotates the motor to automatically tilt down the moon roof. When thelimit SW No.1 is turned off, the pulse signal sent from the HALL IC activates the ECU, and it determines that the moon roof isfully closed, and stops the motor rotation.If other operation SW or tilt down SW is operated while the moon roof is being tilted down, the ECU is activated to stop themoon roof operation.

5. CATCHING PREVENTION FUNCTIONIf the moon roof control ECU detects a catching load from changes in the motor rotation during slide close or tilt downoperation, the operation is stopped, and then the motor is rotated in the reverse direction.Slide close operationThe moon roof is moved approximately 200 mm in the reverse direction (Slide open) after a catching load has beendetected. However, if the full open position is detected before moving approximately 200 mm completely, the reversemovement is stopped.Tilt down operationIf a catching load is detected during tilt down operation, the moon roof is fully tilted up.

SYSTEM OUTLINE

6. KEY OFF MOON ROOF OPERATIONAfter the ignition SW is turned from ON to OFF, communication control of the body ECU and door ECU etc. allows the moonroof operation for 45 sec. However, when the driver or front passenger door is opened during above moon roof operation,the moon roof operation is stopped even though 45 sec. have not elapsed.

7. MOON ROOF OPERATION LINKED WITH TRANSMITTERWhen the unlock SW on the transmitter of the ignition key is kept pressed for 1.5 sec. or longer, the slide open operation ofthe moon roof functions through communication control of the body ECU and door ECU etc.

8. MOON ROOF OPERATION LINKED WITH DOOR KEY LOCK AND UNLOCK SWWhen the ignition key is inserted into the driver door key cylinder and kept turned to the lock or unlock position forapproximately 1.5 sec. or longer, the slide open or close operation of the moon roof functions through communication controlof the body ECU and door ECU etc.

9. FAIL SAFE FUNCTIONIf the moon roof is operated continuously in the same operating direction, the current flowing into the motor is cut off whenthe time shown below has elapsed after the motor operation has been started.Slide open/close operation with the moon roof control SW Approximately 20 sec.Tilt up/down operation with the moon roof control SW Approximately 2 sec.Slide open operation for reverse movement in case of activation of the catching prevention function Approximately 20 sec.Tilt open operation for reverse movement in case of activation of the catching prevention function Approximately 2 sec.

SYSTEM OUTLINE

1. COMMUNICATION OUTLINECommunication is implemented among the body No.1, No.2, driver door, front passenger door, tilt and telescopic, navigation,A/C control assembly, moon roof, power seat, engine control ECUs.Upon receiving signals from applicable switches such as the door lock control switch or door courtesy light switch, each ECUdetermines the conditions of the switches as well as of the doors, and after converting this information into digital signals,outputs them to other ECUs via serial data communication. The ECU that receives these digital signals determines theconditions of the switches and doors so that it can implement various controls such as to activate a door lock motor.However, if there are no changes in the input signals because no doors were opened and no switches were used within 30seconds, the body ECU interrupts the communication to save electricity. Following this interruption, any changes in the inputsignals will cause the communication to resume.For details please refer to the new car features and repair manuals.

1. MANUAL SLIDE OPERATIONWhen the slide SW of the power seat control SW is pressed to FRONT position, the signal is input to TERMINAL (B) 15 ofthe power seat ECU. This activates the power seat ECU to flow the current into TERMINAL (A) 3 of the power seat ECU toTERMINAL 2 of the power seat motor (Slide control) to TERMINAL 1 to TERMINAL (A) 4 of the ECU to GROUND, to movethe seat forward while the power seat control SW is kept pressed.When the slide SW of the power seat control SW is pressed to the REAR position, the signal is input to TERMINAL (B) 16 ofthe power seat ECU. This activates the ECU to flow the current into TERMINAL (A) 4 of the power seat ECU, TERMINAL 1of the power seat motor (Slide control) to TERMINAL 2 to TERMINAL (A) 3 of the ECU to GROUND, to move the seat backbackward.At this time, the power seat position sensor (Slide control) detects the seat position and always inputs it to TERMINAL (B) 14of the power seat ECU.

2. MANUAL RECLINING CONTROLWhen the reclining SW of the power seat control SW is pressed forward, the signal is input to TERMINAL (B) 21 of the powerseat ECU. This activates the power seat ECU to flow the current into TERMINAL (A) 1 of the power seat ECU to TERMINAL1 of the power seat motor (Reclining control) to TERMINAL 2 to TERMINAL (A) 2 of the ECU to GROUND, to tilt the seatback forward while the power seat control SW is kept pressed.When the reclining SW of the power seat control SW is pressed backward, the signal is input to TERMINAL (B) 22 of thepower seat ECU. This activates the ECU to flow the current into TERMINAL (A) 2 of the power seat ECU, TERMINAL 2 ofthe power seat motor (Reclining control) to TERMINAL 1 to TERMINAL (A) 1 of the ECU to GROUND, to tilt the seatbackward.At this time, the power seat position sensor (Reclining control) detects the seat back position and always inputs it toTERMINAL (B) 5 of the power seat ECU.

3. MANUAL FRONT VERTICAL CONTROLWhen the front part of the slide SW of the power seat control SW is pushed up, the signal is input to TERMINAL (B) 19 of thepower seat ECU. This activates the power seat ECU to flow the current into TERMINAL (A) 10 of the power seat ECU toTERMINAL 1 of the power seat motor (Front vertical control) to TERMINAL 2 to TERMINAL (A) 9 of the ECU to GROUND, toraise the front part of the seat cushion while the power seat control SW is kept pressed.When the front part of the slide SW of the power seat control SW is pushed down, the signal is input to TERMINAL (B) 7 ofthe power seat ECU. This activates the power seat ECU to flow the current into TERMINAL (A) 9 of the power seat ECU,TERMINAL 2 of the power seat motor (Front vertical control) to TERMINAL 1 to TERMINAL (A) 10 of the ECU to GROUND,to lower the front part of the seat cushion while the power seat control SW is kept pressed.At this time, the power seat position sensor (Front vertical control) detects the seat cushion position (Front) and alwaysinputs the signal to TERMINAL (B) 3 of the power seat ECU.

4. MANUAL REAR VERTICAL OPERATIONWhen the rear part of the slide SW of the power seat control SW is pushed up, the signal is input to TERMINAL (B) 17 of thepower seat ECU. This activates the power seat ECU to flow the current into TERMINAL (A) 6 of the power seat ECU toTERMINAL 2 of the power seat motor (Rear vertical control) to TERMINAL 1 to TERMINAL (A) 5 of the ECU to GROUND, toraise the seat while the power seat control SW is kept pressed.When the rear part of the slide SW of the power seat control SW is pushed down, the signal is input to TERMINAL (B) 18 ofthe power seat ECU. This activates the ECU to flow the current into TERMINAL (A) 5 of the power seat ECU to TERMINAL 1of the power seat motor (Rear vertical control) to TERMINAL 2 to TERMINAL (A) 6 of the ECU to GROUND, to lower theseat while the power seat control SW is kept pressed.At this time, the power seat position sensor (Rear vertical control) detects the seat cushion position (Rear) and always inputsthe signal to TERMINAL (B) 4 of the power seat ECU.

5. MANUAL LUMBAR SUPPORT OPERATIONWhen the lumbar support control SW is pressed forward, the current flows from the D P/SEAT fuse into TERMINAL 4 toTERMINAL 1 of the lumbar support control SW to TERMINAL 2 of the power seat motor (Lumbar support control) toTERMINAL 1 to TERMINAL 2 of the SW to TERMINAL 3 to GROUND, to move the lumbar support forward.When the SW is pressed backward, the current from the D P/SEAT fuse flows into TERMINAL 4 to TERMINAL 2 of thelumbar support control SW to TERMINAL 1 of the power seat motor (Lumbar support control) to TERMINAL 2 to TERMINAL1 of the SW to TERMINAL 3 to GROUND, to move the lumbar support backward.

6. DRIVING POSITION MEMORY FUNCTIONEach position sensor in the seat detects the number of rotations of the relevant motor (Seat movement amount) and inputs itto the ECU. This makes it possible to store and recall the seat position by operating the position memory SW. The drivingseat position is stored and recalled through communication control of the body ECU and door ECU etc.

* 5 : W/ DRIVING POSITION MEMORY

This system provides the automatic tilt and telescopic mechanisms using the motor drive and ECU control, allowing variablesteering movement in the back and forth, and vertical directions. This makes it possible to set the steering to the desiredsteering position and move the steering to a position where the driver can easily get off the vehicle, allowing easier seating.Additionally, by linking the power seat and remote control mirror, an optimal driving position corresponding to the driver’sneeds can be stored into the memory.

1. AUTO RETURN OPERATIONWhen the ignition key is inserted into the key cylinder (The unlock warning SW is on), the signal is input to the tilt andtelescopic ECU through communication control of the body ECU and door ECU etc. This activates the ECU to automaticallyreturn the steering to the position set before the ignition key has been removed.

2. AUTO AWAY OPERATIONWhen the ignition key is turned from ON to OFF and removed from the key cylinder (The unlock warning SW is off), thesignal is input to the tilt and telescopic ECU through communication control of the body ECU and door ECU etc. Thisactivates the ECU to automatically move the steering to the top tilt step position and maximum telescopic retract position.

3. MANUAL TILT OPERATIONWhen the ignition key is inserted into the key cylinder, the tilt and telescopic can be adjusted.Tilt operationWhen the tilt and telescopic SW is pressed to TILT DOWN position, the current flows from TERMINAL 3 of the tilt andtelescopic ECU into TERMINAL 9 of the tilt and telescopic SW to TERMINAL 4 to TERMINAL 8 of the ECU, and the signal isinput to the ECU. This activates the ECU and starts the tilt control motor to lower the steering while the SW is kept pressed toTILT DOWN position.When the tilt and telescopic SW is pressed to TILT UP position, the current flows from TERMINAL 3 of the tilt and telescopicECU into TERMINAL 9 of the tilt and telescopic SW to TERMINAL 4 to TERMINAL 8 of the ECU, and the signal is input tothe ECU. This activates the ECU and starts the tilt control motor to raise the steering while the SW is kept pressed to TILTUP position.Telescopic operationWhen the tilt and telescopic SW is pressed to TELESCO LONG position, the current flows from TERMINAL 3 of the tilt andtelescopic ECU into TERMINAL 9 of the tilt and telescopic SW to TERMINAL 4 to TERMINAL 8 of the ECU, and the signal isinput to the ECU. This activates the ECU and starts the telescopic control motor to extend the telescopic while the SW iskept pressed to TELESCO LONG position.When the tilt and telescopic SW is pressed to TELESCO SHORT side, the current flows from TERMINAL 3 of the tilt andtelescopic ECU into TERMINAL 9 of the tilt and telescopic SW to TERMINAL 4 to TERMINAL 8 of the ECU, and the signal isinput to the ECU. This activates the ECU and starts the telescopic control motor to retract the telescopic while the SW is keptpressed to TELESCO SHORT position.

4. DRIVING POSITION MEMORY FUNCTIONThe pulse signals detected by the tilt and telescopic sensors are input to the ECU. This makes it possible to store and recallthe desired driving position through communication control of the body ECU and door ECU etc.

POWER WINDOW

1. MANUAL DOWN OR UP OPERATIONThe signal is input to TERMINAL MDN of the driver door ECU while the power window master SW is kept pressed one step.This activates the driver door ECU to flow the current from TERMINAL DN into the power window motor front LH toTERMINAL UP of the driver door ECU to GROUND, to rotate the motor and open the window.The signal is input to TERMINAL MUP of the driver door ECU while the power window master SW is kept pulled one step.This activates the driver door ECU to flow the current from TERMINAL UP into the power window motor front LH toTERMINAL DN of the driver door ECU to GROUND, to reversely rotate the motor and close the window. For other windows,as the power window master SW or each power window SW is operated, the window of the relevant door is opened orclosed.

2. AUTO DOWN OR UP OPERATIONThe signals are input to TERMINALS MDN and AUTO of the driver door ECU when the power window master SW is pressedtwo steps. According to these signals, it is determined that the driver door ECU is in the auto mode. The current flows fromTERMINAL DN into the power window motor front LH to TERMINAL UP of the driver door ECU to GROUND, to rotate themotor and automatically open the window. Accordingly, when each window switch of the power window master SW ispressed, the window of the relevant door is automatically opened through communication control of the body ECU and doorECU etc.The signals are input to TERMINALS MUP and AUTO of the driver door ECU when the power window master SW is pulledtwo steps. According to these signals, it is determined that the driver door ECU is in the auto mode. The current flows fromTERMINAL UP into the power window motor front LH to TERMINAL DN of the driver door ECU to GROUND, to rotate themotor and automatically close the window. Accordingly, when each window switch of the power window master SW ispressed, the window of the relevant door is automatically closed through communication control of the body ECU and doorECU etc.For other windows, as each power window control SW is operated, the window of the relevant door is automatically openedor closed.

3. POWER WINDOW OPERATION LINKED WITH DOOR KEY LOCK AND UNLOCK SWWhen the ignition key is inserted into the door key cylinder on the driver or passenger side and kept turned to the lock orunlock position for approximately 1.5 sec. or longer, all the door windows can be opened or closed.Power window close operationWhen the ignition key is inserted into the door key cylinder and kept turned to the lock position for 1.5 sec. or longer, thesignal from the door key lock and unlock SW is input to TERMINAL KL of the driver door ECU or front passenger door ECU.Through communication control of the body ECU and door ECU etc. , the current flows from TERMINAL UP of each doorECU into the power window motor to TERMINAL DN of the each door ECU to GROUND, to close all the door windows.Power window open operationWhen the ignition key is inserted into the door key cylinder and kept turned to the unlock position for 1.5 sec. or longer, thesignal from the door key lock and unlock SW is input to TERMINAL KUL of the driver door ECU or front passenger doorECU. Through communication control of the body ECU and door ECU etc. , the current flows from TERMINAL DN of eachdoor ECU into the power window motor to TERMINAL UP of the each door ECU to GROUND, to close all the door windows.If any of the following conditions is detected, the power window operation is stopped.Approximately 10 sec. or longer has elapsed after starting open/close operation. Catching prevention function is activated.

4. POWER WINDOW OPERATION LINKED WITH TRANSMITTERWhen the unlock SW on the transmitter of the ignition key is kept pressed for 1.5 sec. or longer, all the door windows can beopened.Power window open operationWhen the unlock SW of the ignition key is kept pressed for 1.5 sec. or longer, the frequency received from the wireless doorlock control ECU is input to the body ECU No.1. Through communication control of the body ECU and door ECU etc. , thecurrent flows from TERMINAL DN of each door ECU into the power window motor to TERMINAL UP of the each door ECUto GROUND, to open all the door windows.If any of the following conditions is detected, the power window operation is stopped.Approximately 10 sec. or longer have elapsed after starting open operation.The lock or unlock switch on the transmitter is released.Catching prevention function is activated.

5. CATCHING PREVENTION FUNCTIONIf any foreign matter is caught in the window while it is rising, the pulse sensor installed in the power window motor detectschanges in the number of motor rotations, forcibly lowers the door window 50 mm or if the door window opening amount is200 mm or less, the window is lowered so that the opening amount is 200 mm.

6. KEY OFF POWER WINDOW OPERATIONIt is possible to operate the power window for 45 sec. after the ignition key is turned from ON to OFF and the driver or frontpassenger door is opened. However, when the door is closed while the window is being operated, the power windowoperation is stopped even though 45 sec. has not elapsed.

PPS ECU (Flow rate control system) controls the solenoid valves mounted in the pump to conduct direct control of the pumpflow rate in response to the vehicle speed possible, ensuring natural and real steering feeling.

1. PPS OPERATIONWhen the ignition SW is turned on, the starting current flows from the ECU–IG fuse to TERMINAL 4 of the PPS ECU. Thevehicle speed sensor monitors the vehicle speed and transmits control signals to TERMINAL 5 of the ECU.When the vehicle speed is low, the PPS ECU sends a higher–current from TERMINAL 1 of the ECU to TERMINAL 1 of thePPS solenoid to TERMINAL 2 to TERMINAL 2 of the ECU to TERMINAL 6 to GROUND, increasing the solenoid valveopening angle to provide comfortable steering operation. When the vehicle speed is high, the PPS ECU decreases thesolenoid valve opening angle by reducing the current to the valve to provide responsive steering feeling.

P3 PPS SOLENOID1–2 : Approx. 7.8 Ω (25°C, 77°F)

P6 PPS ECU4–GROUND : Approx. 12 volts with ignition SW at ON or ST position6–GROUND : Always continuity

RADIATOR FAN AND CONDENSER FAN

FAN MOTOR OPERATIONWhen the ignition SW is turned on, the current from the IGN fuse flows to the FAN NO.1 relay (Coil side) and the FAN NO.2relay (Coil side) to TERMINAL 3 of the A/C single pressure SW to TERMINAL 2 to TERMINAL 2 of the water temp. SW toTERMINAL 1 to GROUND, and the FAN NO.1 relay is turned off and the FAN NO.2 relay is turned on.

∗ Low speed operationWhen the ignition SW is turned on and the A/C is activated, current flows from the A/C COMP relay (Point side) to theFAN NO.3 relay (Coil side) to GROUND, and the FAN NO.3 relay is turned on. As a result, current from the CDS FANfuse flows to TERMINAL 2 of the A/C condenser fan motor to TERMINAL 1 to the FAN NO.2 relay (Point side) to theFAN NO.3 relay (Point side) to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND, rotating both of thefan motors at low speed.If the engine coolant temperature is approx. 90°C (194°F) or less, and the refrigerant pressure is approx. 15.5 kgf/cm2

(1520 kpa, 220.4 psi) or less, both the water temp. SW and the A/C signal pressure SW are closed, so that the FANNO.1 relay is turned off and the FAN NO.2 relay is turned on. As a result, both of the fan motor operate at low speed.

∗ High speed operationWhen, during A/C operation, the refrigerant pressure becomes higher than ordinary level (Approx. 15.5 kgf/cm2 (1520psi, 220.4 kpa) ), the A/C single pressure SW is turned off. As a result, the FAN NO.1 relay is turned on and FAN NO.2relay is turned off, and the current flows from the RDI FAN fuse to FAN NO.1 relay (Point side) to TERMINAL 2 of theradiator fan motor to TERMINAL 1 to GROUND, and current from the CDS FAN fuse flows to TERMINAL 2 of the A/Ccondenser fan motor to TERMINAL 1 to the FAN NO.2 relay (Point side) to GROUND, rotating both of the fan motors inparallel, thus causing the fan motors to operate at high speed.Note that, because the current flows in the same manner even if the coolant temperature is approx. 90°C (194°F) orhigher, the fan motors still operate at high speed.

A4 A/C SINGLE PRESSURE SW2–3 : Open above approx. 15.5 kgf/cm2 (220.4 psi, 1520 kpa)

Close below approx. 12.5 kgf/cm2 (177.7 psi, 1225.8 kpa)

REMOTE CONTROL MIRROR OPERATIONWhen the ignition SW is turned to the ACC or ON position, the outer mirrors can be operated. When the remote controlmirror SW is operated, the signal is input to body ECU No.2 and the outer mirror is adjusted to the desired position throughcommunication control of the body ECU and door ECU etc.In the remote control mirror system, the position sensor detects the number of rotations of each motor (Movement amount ofeach mirror) and inputs it to the ECU. This makes it possible to store and recall the outer mirror position using the positionmemory SW. The outer mirror position is stored and recalled through communication control of the body ECU and door ECUetc.

1. SHIFT LOCK MECHANISMIf the brake pedal is depressed with the ignition SW set at ON (The stop light SW is on), the shift lock control ECU isactivated, allowing the driver to change the shift lever to a position other than the P position.

2. REVERSE INHIBIT MECHANISMChanging the shift lever to the R position is inhibited by operation of the shift lock control ECU and body ECU No.2 while thevehicle is travelling forward.If the vehicle speed is almost 0 km/h, the signal is input to TERMINAL 8 of the shift lock control ECU through communicationcontrol of the body ECU and door ECU etc. , allowing the driver to change the shift lever to the R position.

3. KEY INTERLOCK MECHANISMWhen the ignition SW is turned to the ACC or ON position and the shift lever is at a position other than the P position, theshift lock control ECU is activated to flow the current into the key interlock solenoid. This inhibits to turn the ignition SW fromthe ACC position to the OFF position.

SRS

NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionaryinstructions and the procedure and precautions in the Repair Manual for the applicable model year.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

Work must be started after 90 seconds from when the ignition switch is turned to the ”LOCK” position and thenegative (–) terminal cable is disconnected from the battery.(The SRS is equipped with a back–up power source so that if work is started within 90 seconds fromdisconnecting the negative (–) terminal cable of the battery, the SRS may be deployed.)

When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becanceled. So before starting work, make a record of the contents memorized in the audio memory system. When work isfinished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in eachmemory system, never use a back–up power supply from outside the vehicle.

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner,center airbag sensor assembly, front airbag sensor or side airbag sensor assembly directly to hot air or flames.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbagassembly, side airbag assembly, seat belt pretensioner, center airbag sensor assembly, front airbag sensor assemblyand side airbag sensor assembly should be inspected.

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat beltpretensioner center airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly in order toreuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, center airbagsensor assembly, front airbag sensor assembly or side airbag sensor assembly has been dropped, or if there arecracks, dents or other defects in the case, bracket or connector, replace them with new ones.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.

After work on the SRS is completed, perform the SRS warning light check or SRS side airbag warning light check.

If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

SRS

The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.When the ignition SW is turned to ACC or ON, the current from the SRS–ACC fuse flows to TERMINAL (B) 6 of the centerairbag sensor assembly. Only when the ignition SW is on does the current flow from the IGN fuse to TERMINAL (B) 5 of thecenter airbag sensor assembly.If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the SRS–ACC or IGN fuseflows to TERMINALS (B) 14, (B) 10, (C) 5 and (A) 2 of the center airbag sensor assembly to TERMINAL 1 of the airbagsquibs and the pretensioners to TERMINAL 2 to TERMINALS (B) 13, (B) 11, (C) 6 and (A) 1 of the center airbag sensorassembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, so that current flows to the airbag squibs and thepretensioners and causes them to operate.When the side impact also exceeds a set level, the current from the SRS–ACC or IGN fuse flows to TERMINALS (C) 2, (A)5, (C) 5 and (A) 2 of the center airbag sensor assembly to TERMINAL 1 of the side airbag squibs and the pretensioners toTERMINAL 2 to TERMINALS (C) 1, (A) 6, (C) 6 and (A) 1 of the center airbag sensor assembly to TERMINAL (B) 27, (B) 28or BODY GROUND to GROUND, causing side airbag squibs and the pretensioners to operate.The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to the frontpassenger.Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.The pretensioners make sure of the seat belt restrainability.

STOP LIGHT

The current always flows from the STOP fuse into TERMINAL 2 of the stop light SW. If the brake pedal is depressed, thestop lights light up.

STOP LIGHT DISCONNECTION WARNINGIf any stop light wiring is faulty when the brake pedal is depressed with the ignition SW set at ON, the light failure sensordetects a voltage difference and inputs the signal to TERMINAL 4 of the body ECU No.2. The body ECU No.2 controls thecombination meter through the communication to turn on the rear lights warning light to warn the driver. The warning light isremained lit until the ignition SW is turned to the OFF position.

TAILLIGHT

When the light control SW is turned to the TAIL or HEAD position, the signal is input to TERMINAL TAIL of the body ECUNo.2. This activates the body ECU No.2 to flow the current from the battery into the ALT fuse, TAIL relay (Coil side),TERMINAL TRLY of the body ECU No.2 to GROUND in that order to turn on the TAIL relay. The current flows from the TAILfuse into the parking lights, front side marker lights, license plate lights, TERMINAL 5 of the light failure sensor to TERMINAL7 and 12 to taillights, and rear side marker lights in that order to turn on each light.

TAILLIGHT DISCONNECTION WARNINGIf any taillight wiring is faulty when the ignition SW is turned to the ON position with the light control SW set at TAIL or HEAD,the light failure sensor detects a voltage difference and inputs the signal to TERMINAL LF of the body ECU No.2. The bodyECU No.2 is activated to turn on the rear lights warning light in the combination meter to warn the driver.

1. MANUAL UNLOCK OPERATIONWhen the door lock control SW on the driver or front passenger seat is pressed to the unlock position, the signal is input toTERMINAL MUL of the driver door ECU or front passenger door ECU. Through communication control of the body ECU anddoor ECU etc. , the current flows from TERMINAL A– of the door ECU into the door lock motor to TERMINAL A+ of the doorECU to GROUND, to unlock the door.

2. MANUAL LOCK OPERATIONWhen the door lock control SW on the driver or front passenger seat is pressed to LOCK, signal is input to TERMINAL ML ofthe driver door ECU or front passenger door ECU. Through communication control of the body ECU and door ECU etc. ,current flows from TERMINAL A+ of the door ECU to door lock motor to TERMINAL A– of the door ECU to GROUND, to lockthe door.

3. DOOR KEY UNLOCK OPERATIONUnlock operation from driver doorWhen the door is unlocked once by the ignition key from the driver side, the signal from the door key lock and unlock SW inthe door lock motor front LH is input to TERMINAL KUL of the driver door ECU. This signal activates the driver door ECU toflow the current from TERMINAL A+ of the driver door ECU into the door lock motor front LH to TERMINAL A+ of the driverdoor ECU to GROUND, to unlock only the driver door. Accordingly, if the second unlock operation is made within 3 sec. afterthe above unlock operation, all the doors are unlocked through communication control of the body ECU and door ECU etc.Unlock operation from passenger doorWhen the door is unlocked by the ignition key from the front passenger side, the signal from the door key lock and unlockSW in the door lock motor front RH is input to TERMINAL KUL of the front passenger door ECU. Through communicationcontrol of the body ECU and door ECU etc. , the current flows from TERMINAL A– of the door ECU into the door lock motorfront RH to TERMINAL A+ of the door ECU to GROUND, to unlock all the doors at once.

4. IGNITION KEY REMINDER OPERATIONWhen the door lock operation is made using the door knob with the ignition key remained inserted in the key cylinder and thedoor open, unlock operation is automatically made. Additionally, if lock operation is made with the door lock control SW ordoor key lock and unlock SW, unlock operation is automatically made after the lock operation has been completed.

1. ABS OPERATIONIf the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the fourwheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedalis depressed suddenly, the ABS & TRAC & VSC ECU controls the solenoids in the actuators using the signals from thesensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If theABS & TRAC & VSC ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the solenoidsin the actuators to increase the braking pressure.

2. TRACTION CONTROL OPERATIONThe traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of thewheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stabilitycorresponding to the road conditions.

3. VSC OPERATIONUnexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under– orover–steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes toreduce the under– or over–steering.To reduce large over–steering :If the VSC system determines that the over–steering is large, it activates the brakes for the outer turning wheels dependingon the degree of the over–steering to produce the moment toward the outside of the vehicle and reduce the over–steering.To reduce large under–steering :If the VSC system determines that the under–steering is large, it controls the engine power and activates the rear wheelbrakes to reduce the under–steering.VSC OFF SWThe VSC OFF SW is used to stop the VSC function. After the engine is started, the VSC system is stopped (turned off) andthe VSC OFF indicator light lights up. When the VSC OFF SW is pressed again, the VSC system enters the stand–by mode.If the engine is stopped and restarted, the VSC system enters the stand–by mode regardless of the VSC OFF SW.VSC indicator lightIf an error occurs in the VSC system, the VSC indicator lights up to warn the driver.

4. MUTUAL SYSTEM CONTROLTo efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlledwhile the VSC system is being operated.Engine throttle controlThe engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing theengine output.Engine control and electronically controlled transmission controlThe strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. andreducing changes in the driving torque at shift–down.VSC system operation indicationThe slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, whilethe VSC system is being operated.

5. FAIL SAFE FUNCTIONIf an error occurs in the ABS & TRAC & VSC ECU, sensor signals, and/or actuators, the ABS & TRAC & VSC ECU inhibitsthe brake actuator control and inputs the error signal to the engine control module. According to the error signal, the brakeactuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open request fromthe VSC system. As a result, the vehicle functions without the ABS, TRAC, and VSC systems.

With the ignition SW turned on, the current flows to TERMINAL 17 of the front wiper and washer SW, and TERMINAL 2 ofthe front wiper motor through the WIPER fuse, TERMINAL 2 of washer motor through the WASHER fuse.

1. LOW SPEED POSITIONWith wiper SW turned to LO position, the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND and causes the front wiper motor to run at lowspeed.

2. HIGH SPEED POSITIONWith wiper SW turned to HI position, the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 8to TERMINAL 3 of the front wiper motor to TERMINAL 4 to GROUND and causes the front wiper motor to run at high speed.

3. INT POSITIONWith wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows fromTERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This flow of current operates the intermittentcircuit and the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 5 of thefront wiper motor to TERMINAL 4 to GROUND and operates the wiper.The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and theintermittent time is controlled by a time control SW to change the charging time of the condenser.

4. MIST POSITIONWith wiper SW turn MIST position, the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 toTERMINAL 5 of the wiper motor to TERMINAL 4 to GROUND and causes the wiper motor to run at low speed.

5. WASHER CONTINUOUS OPERATIONWith washer SW turned to on, the current flows from TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 11 ofthe front wiper and washer SW to TERMINAL 2 to GROUND and causes to the washer motor to run, and the window washeremits a water spray. This causes the current to flow to washer continuous operation circuit in TERMINAL 17 of the frontwiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND and operatesthe wiper.

In this system, the wireless door lock ECU receives weak radio wave transmitted from the transmitter built–into the ignitionkey and outputs the signal to the body ECU No.2. Through communication control of the body ECU and door ECU etc. , allthe doors and the luggage door can be locked and unlocked by the remote control.

1. NORMAL OPERATIONLock operationWhen the lock SW on the transmitter is pressed, all the doors are locked.Unlock operationWhen the unlock SW on the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressedagain within 3 sec., all the doors are unlocked.Luggage door unlock operationWhen the luggage door unlock SW is kept pressed for approximately 1 sec. or longer, the luggage door is opened.

2. AUTO LOCK FUNCTIONIf the door is not actually opened within 30 sec. after the door has been unlocked by pressing the unlock SW on thetransmitter, all the doors are automatically locked. If any of the following conditions is detected, the auto lock does notfunction.Any door is opened.The ignition key is inserted into the ignition SW.When the lock detection SW of all the doors are locked.

3. WIRELESS DOOR LOCK STOP FUNCTIONIf any of the following conditions is detected, the wireless door lock does not function.Lock operationAny door is open (The door courtesy SW is on). The ignition key is inserted into the ignition key cylinder (The unlock warningSW is on). The ignition SW is turned to the ON position.Unlock operationThe ignition SW is turned to the ON position.Luggage door unlock operationThe ignition SW is turned to the ON position.

4. BUZZER SOUND FUNCTIONWhen the body ECU No.1 receives the door lock signal from the door ECU via the door lock motor, during lock operation, thewireless door lock buzzer goes on once (for approximately 0.1 sec.).When the body ECU No.1 receives the door unlock signal from the door ECU via the door lock motor, during unlockoperation, the wireless door lock buzzer goes on twice (for approximately 0.2 sec. at intervals of 0.1 sec.).When the luggage door is unlocked, and the body ECU No.1 outputs the unlock signal, the wireless door lock buzzer goeson once (for approximately 0.5 sec.).When the body ECU No.1 receives the lock signal from the transmitter while any door is open, the wireless door lock buzzersounds for approximately 10 sec. If the door is closed or if the unlock signal is received from the transmitter while the buzzeris sounding, the buzzer stops.

5. CAR FINDER FUNCTIONWhen the lock SW on the transmitter is pressed with all the doors locked, the body ECU No.1 receives the signal and thehazard light flashes once through communication control of the body ECU and door ECU etc.

6. ILLUMINATED ENTRY FUNCTIONWhen the body ECU No.2 detects the unlock state after the unlock operation has been made, it turns on the lights, such asthe ignition key cylinder light for 15 sec. If all the doors are locked during this operation, lighting is cancelled and the lightsimmediately fade out.

7. PANIC MODE FUNCTIONWhen the lock switch on the transmitter is kept pressed for approximately 2.5 sec., the body ECU No.1 receives the signaland enters the panic mode. The theft alarm goes on upon receiving the signal, the body ECU No.1, and the headlights andtaillights flash through the communication of the body ECU and door ECU etc. At this time, when any SW on the transmitteris pressed, the panic mode is cancelled, the theft alarm is stopped, and the headlights and taillights go off.

8. REPEAT FUNCTIONIf the lock detection signal in response to the output signal is not received after the body ECU No.1 has output the locksignal, the lock signal is output again after approximately 2 sec.
