HOW TO DIAGNOSE M16DAA6

L

The most important point in troubleshooting is to determine “Probable Causes”. Once the probable causesare determined, parts to be checked can be limited to those associated with such probable causes. Therefore,unnecessary checks can be eliminated. The determination of the probable causes must be based on a theoryand be supported by facts and must not be based on intuition only.

TROUBLESHOOTING STEPSIf an attempt is made to solve a problem without going through correct steps for troubleshooting, the problemsymptoms could become more complicated, resulting in failure to determine the causes correctly and makingincorrect repairs. The four steps below should be followed in troubleshooting.

Observe the symptom carefully.Check if there are also other problems.

In determining the probable causes, it is necessary tocheck the wiring diagram to understand the circuit as asystem. Knowledge of switches, relays and other parts isnecessary for accurate determination. The causes ofsimilar problems in the past must be taken into account.

I Troubleshooting is carried out by making step by stepchecks until the true cause is found. Always go throughthe procedures considering what check is to be madewhere for the best results.

14 1 Repair and ConfirmationAfter the problems are corrected, be sure to check thatthe system operates correctly. Also, check that newproblems have not been caused by the repair.

INFORMATION FOR DIAGNOSISThis manual contains the cable diagrams as well as the individual circuit drawings, operational explanations,and troubleshooting hints for each component required to facilitate the task of troubleshooting. Theinformation is compiled in the following manner:(1) Cable diagrams show the connector positions, etc., on the actual vehicle as well as the harness path.(2) Circuit drawings show the configuration of the circuit with all switches in their normal positions.(3) Operational explanations include circuit drawings of voltage flow when the switch is operated and how

the component operates in reaction.(4) Troubleshooting hints include numerous examples of problems which might occur, traced backward in a

common-sense manner to the origin of the trouble.Problems whose origins may not be found in this manner are pursued through the various system circuits.NOTE

I

LjComponents of ECI, ETACS, ECS, etc. with ECU do not include 3 and 4 above. For this information, referto a manual which includes details of these components.

INSPECTION1. Visual and aural checks \

Check relay operation, blower motor rotation, light illumi ht!Jtion, etc. visually or aurally. The flow of current is invisiblebut can be checked by the operation of the parts.

2. Simple checksFor example, if a headlight does not come on and a faultyfuse or poor grounding is suspected, replace the fuse with anew one or ground the light to the body by a jumper wire todetermine which part is responsible for the problem.

3. Checking with instrumentsUse an appropriate instrument in an adequate range andread the indication correctly. You must have sufficientknowledge and experience to handle instruments correctI\* \

!L)

INSPECTION INSTRUMENTSIn inspection, make use of the following instruments.1. Test lights

A test light consists of a 12V bulb and lead wires. It is usedto check voltages or shortcircuits.

2. Self-power test lightA self-power test light consists of a bulb, battery and leadwires connected in series. It is used to check continuity orgrounding.

4. VoltmeterA voltmeter is used to measure the circuit voltage.Normally, the positive (red lead) probe is applied to the pointof voltage measurement and the negative (black lead) probeto the body ground.

5. OhmmeterAn ohmmeter is used to check continuity or measureresistance of a switch or coil. If the measuring range hasbeen changed, the zero point must be adjusted beforemeasurement.

CHECKING SWITCHESIn a circuit diagram, a switch is represented by a symbol and inthe idle state.1. Normal open or normal close switch

Switches are classified into those which make the circuitopen and those which make the circuit closed when off.

CHECKING RELAYS1. When current flows through the coil of a relay, its core is

magnetized to attract the iron piece, closing (ON) thecontact at the tip of the iron piece. When the coil current \,turned off, the iron piece is made to return to its origiljl/iposition by a spring, opening the contact (OFF).

2. By using a relay, a heavy current can be turned on and off bya switch of small capacity. For example, in the circuit shownhere, when the switch is turned on (closed), current flowsto the coil of the relay. Then, its contact is turned on(closed) and the light comes on. The current flowing at thistime to the switch is the relay coil current only and is verysmall.

3. The relays may be classified into the normal open type andthe normal cl,ose type by their contact construction.NOTEThe deenergized state means that no current is flowingthrough the coil and the energized state means that currentis flowing through the coil.

When a normal close type relay. as illustrated here ischecked, there should be continuity between terminals (1)and (2) and between terminals 3 and 4 when the relay isdeenergized, and the continuity should be lost betweenterminals 3 and 4 when the battery voltage is applied to theterminals 1 and 2. A relay can be checked in this mannerand it cannot be determine if a relay is okay or faulty bychecking its state only when it is deenergized (or ener-gized).

CHECKING FUSESA blade type fuse has test taps provided to allow checking ofthe fuse itself without removing it from the fuse block. Thefuse is okay if the test light comes on when its one lead isconnected to the test taps (one at a time) and the other lead isgrounded. (Change the ignition switch position adequately sothat the fuse circuit becomes live.)

CAUTIONS IN EVENT OF BLOWN FUSEWhen a fuse is blown, there are two probable causes asfollows: One is that it is blown due to flow of current exceedingits rating.The other is that it is blown due to repeated on/off currentflowing through it. Which of the two causes is responsible canbe easily determined by visual check as described below.(1) Fuse blown due to current exceeding rating

The illustration shows the state of a fuse blown due to thiscause. In this case, do not replace the fuse with a new onehastily since a current heavy enough to blow the fuse hasflowed through it. First, check the circuit for shorting andcheck for abnormal electric parts. Only after the correctionof such shorting or parts, fuse of the same capacity shouldbe used as a replacement. Never use a fuse of largercapacity than the one that has blown. If such a fuse is used,electric parts or wirings could be damaged before the fuseblows in the event an overcurrent occurs again.

(2) Fuse blown due to repeated current on/offThe illustration shows the state of a fuse blown due torepeated current on/off. Normally, this type of problemoccurs after fairly long period of use- and hence is lessfrequent than the above type. In this case, you may simplyreplace with a new fuse of the same capacity.

CHECKING CABLES AND WIRES1. Check connections for looseness, rust and stains.2. Check terminals and wires for corrosion by battery electAJ

lyte, etc.3. Check terminals and wires for open circuit or impending

open circuit.4 . Check wire insulation and coating for damage, cracks and

degrading.5. Check conductive parts of terminals for contact with other

metallic parts (vehicle body and other parts).6. Check grounding parts to verify that there is complete

continuity between attaching bolt(s) and vehicle body.7. Check for incorrect wiring.8. Check that wirings are so clamped as to prevent contact

with sharp corners of the vehicle body, etc. or hot parts(exhaust manifold, pipe, etc.).

9. Check that wirings are clamped firmly to secure enoughclearance from the fan pulley, fan belt and other rotating ormoving parts.

10. Check that the wirings between the fixed parts such as thevehicle body and the vibrating parts such as the engine aremade with adequate allowance for vibrations.

HANDLING ON-VEHICLE BATTERYWhen checking or servicing does not require power from theon-vehicle battery, be sure to disconnect the cable from thebattery (-1 terminal. This is to prevent problems that could t \caused by shorting of the circuit. Disconnect the (-) term?first and reconnect it last.

d

TROUBLESHOOTINGA circuit consists of the power supply, switch, relay, load,ground, etc. There are various methods to check a circuitincluding an overall check, voltage check, shortcircuit checkand continuity check. Each of these methods is brieflydescribed in the following.1. VOLTAGE CHECK

(I) Ground one lead wire of the test light. If a voltmeter isused instead of the test light, ground the grounding sidelead wire.

(2) Connect the other lead wire of the test light to thepower side terminal of the switch connector. The testlight should come on or the voltmeter should indicate avoltage.

(3) Then, connect the test light or voltmeter to the motorconnector. The test light should not come on, or thevoltmeter should indicate no voltage. When the switchis turned on in this state, the test light should come on,or the voltmeter should indicate a voltage, with motrstarting to run.

y’(4) The circuit illustrated here is normal but if there is anproblem such as the motor failing to run, check voltagesbeginning at the connector nearest to the motor untilthe faulty part is identified.

16-4 CHARGING SYSTEM - Troubleshooting

OPERATIONWhen engine is stoppedWhen the ignition switch is switched to the “ON”position, electricity flows from the “L” terminal ofthe alternator to the field coil, and at the same timethe charging warning light illuminates.

When engine is being started/has startedWhen the engine is started, charging voltage isapplied to the “L” terminal of the alternator, withthe result that the charging warning light is extin-guished.In addition, because battery voltage is applied to the“S” terminal of the alternator, this battery voltage ismonitored at the IC voltage regulator, thus switch-ing ON and OFF the current to the field coil andthereby controlling the output voltage of the alterna-tor.Power is supplied to each load from the “B”terminal of the alternator.

NOTEThe alternator relay functions as a back-up for theflow of electricity to’ the field coil if there is adisconnection or damaged wiring of the chargingwarning light.

TROUBLESHOOTING HINTS1. Charging warning light does not go on when the ~

ignition switch is turned to “ON”, before thengine starts. I)

l Check the bulb.

2. Charging warning light fails to go off once theengine starts.l Check the IC voltage regulator (located

within the alternator).

3. Discharged or overcharged battery.l Check the IC voltage regulator (located

within the alternator).

4. The charging warning light illuminates dimly.l Check the diode (within the combination

meter) for a short-circuit.

CHARGING SYSTEM INSPECTION MlGEIAN

VOLTAGE DROP TEST OF ALTERNATOR OUT-PUT WIREThis test judges whether or not the wiring (includingthe fusible link) between the alternator B terminaland the battery (+) terminal is sound by the voltagedrop method.

Preparation(1) Turn the ignition switch to “OFF”.(2) Disconnect the battery ground cable.(3) Disconnect the alternator output lead from the

alternator “B” terminal.(4) Connect a DC ammeter in series to the “B”

terminal and the disconnected output lead.Connect the (+) lead of the ammeter to the “B”terminal and the (-) lead to the disconnectedoutput wire.

NOTEUse of a clamp type ammeter that can measurecurrent without disconnecting the harness ispreferred. The reason is that when checking avehicle that has a low output current due to poorconnection of the alternator “B” terminal, suchpoor connection is corrected as the “8” terminalis loosened and a test ammeter is connected inits place and as a result, causes for the troublemay not be determined.

(5) Connect a digital voltmeter between the alterna-tor “B” terminal and battery (+) terminal. Con-nect the (+) lead wire of the voltmeter to the“B” terminal and the (-) lead wire to the battery(+) terminal.

(6) Connect the battery ground cable.(7) Leave the hood open.

Voltmeter Ammeter

Test(1) Start the engine.(2) Turn on or off the headlights and small lights and

adjust the engine speed so that the ammeterreads 20 A and read off the voltmeter indicationunder this condition.

Result(1) It is okay if the voltmeter indicates the standard

value.

Standard value: 0.2 V max.(2) If the voltmeter indicates a value that is larger

than the standard value, poor wiring is sus-pected, in which case check the wiring from thealternator “B” terminal to fusible link to battery(+) terminal. Check.for loose connection, colorchange due to overheated harness, etc. and

i

correct them before testing again.

(3) Upon completion of the test, set the enginespeed at idle.Turn off the lights and turn off the ignitionswitch.

(4) Disconnect the battery ground cable.(5) Disconnect the ammeter and voltmeter that

have been connected for the test purpose.(6) Connect the alternator output wire to the alter-

nator “B” terminal.(7) Connect the battery ground cable.

16-6 CHARGING SYSTEM - Service Adjustment Procedures

OUTPUT CURRENT TESTThis test judges whether or not the alternator givesan output current that is equivalent to the nominaloutput.

Preparation(I) Prior to the test, check the following items and

correct as necessary.(a) Check the battery installed in the vehicle to

ensure that it is in sound state*. The batterychecking method is described in “BAT-TERY”

NOTE‘“The battery that is used to test the outputcurrent should be one that has been ratherdischarged. With a fully charged battery, thetest may not be conducted correctly due toan insufficient load.

(b) Check tension of the alternator drive belt.The belt tension check method is describedin “GROUP 11 - Engine Adjustment”

(2) Turn off the ignition switch.(3) Disconnect the battery ground cable.(4) Disconnect the alternator output wire from thu

alternator “B” terminal.(5) Connect a DC ammeter in series between the

“B” terminal and the disconnected output wire.Connect the (+) lead of the ammeter to the “B”terminal and connect the I-) lead wire to thedisconnected output wire.

NOTETighten each connection by bolt and nut secure-ly as a heavy current will flow. Do not relay onclips.

(6) Connect a voltmeter (0 to 20V) between the “B”terminal and ground. Connect the (+) lead wireto the alternator “B” terminal and (-) lead wireto a sound ground.

(7) Set the engine tachometer and connect thebattery ground cable.

(8) Leave the engine hood open.

Test(1) Check to see that the voltmeter reads the same

value as the battery voltage.If the voltmeter reads OV, an open circuit in thewire between the alternator “B” terminal andbattery (-) terminal, a blown fusible link or poorgrounding is suspected.

(2) Turn on the headlight switch and start theengine.

(3) Set the headlight at high beam and the heaterblower switch at HIGH, quickly increase theengine speed to 2,500 rpm and read themaximum output current value indicated by theammeter.

NOTEAfter the engine start up, the charging currentquickly drops, therefore, above operation mustbe done quickly to read maximum current valuecorrectly.

Result(1) The ammeter reading must be higher than the

limit value. If it is lower but the alternator outputwire is normal, remove the alternator from thevehicle and check it.

Limit: 77A min.Caution(a) The nominal output current value is

shown on the name plate affixed to thealternator body.

(b) The output current value changes withthe electrical load and the temperature ofthe alternator itself.Therefore, the nominal output currentmay not be obtained if the vehicle elec-trical load at the time of test is small.

In such a case, keep the headlights on tocause discharge of the battery or uselights of another vehicle as a load toincrease the electrical load. The nominaloutput current may not be obtained if thetemperature of the alternator itself orambient temperature is too high. In sucha case, reduce the temperature beforetesting again.

(2) Upon completion of the output current test,lower the engine speed to the idle speed andturn off the ignition switch.

(3) Disconnect the battery ground cable.(4) Remove the test ammeter and voltmeter and

the engine tachometer.(5) Connect the alternator output wire to the alter-

nator “B” terminal.(6) Connect the battery ground cable.

REGULATED VOLTAGE TESTThe purpose of this test is to check that theelectronic voltage regulator controls the voltagecorrectly.

Preparation

L(1) Prior to the test, check the following items and

correct if necessary.(a) Check the battery installed on the vehicle to

see that it is fully charged. For batterychecking method, see “BATTERY”.

(b) Check the alternator drive belt tension. Forbelt tension check, see “GROUP 11 -Engine Adjustment”

(2) Turn the ignition switch to “OFF”.(3) Disconnect the battery ground cable.(4) Connect a digital voltmeter between the “S”

terminal of the alternator and ground. Connectthe (+) lead of the voltmeter to the “S” terminalof the alternator, inserting from the wire side ofthe 2-way connector and connect the (-) lead tosound ground or battery I--) terminal.

BATTERY CHARGINGCaution

M’SEICM

When batteries are being charged, an explosivegas forms beneath the cover of each cell. Do notsmoke near batteries on charge or which haverecently been charged.Do not break live circuits at the terminals of thebatteries on charge. A spark will occur wherethe live circuit is broken.Keep all open flames away from the battery.Battery electrolyte temperature may temporarily beallowed to rise to 55°C (131°F). Increase of electro-lyte temperature above 55°C (131°F) is harmful tothe battery, causing deformation of battery cell,decrease in life of battery, etc.

CHARGE RATE

ij If the test indicator is white, the battery should be

charged as outlined below.

OPEN CIRCUIT VOLTAGE TEST (3)1. Turn headlights on for 15 seconds.2. Turn headlights off for 2 minutes to allow battery

voltage to stabilize.3. Disconnect cables.4. Read open circuit voltage.5. If the open circuit voltage is under 12.4 volts,

charge the battery. (See BATTERY CHARGING)

LOAD TEST (4)1. Connect a load tester to the battery.2. Load the battery at 15 amps for 15 seconds to

remove surface charge.3. Load the battery at the recommended discharge

rate. (See LOAD TEST RATE CHART.)4. Read voltage after 15 seconds and then remove

the load.5. If the voltage is not maintained at the minimum

voltage in the LOAD TEST CHART throughoutthe test, the battery should be replaced.

When the dot appears or when maximum chargeshown below is reached, charging should be stop-ped.

NOTEWhen the charging is performed at 5 amps, charg-ing is virtually 100% three hours after the indicator’sindication changes from white to green.Use fast charging only in an emergency.If the indicator does not turn to green even after thebattery is charged, the battery should be replaced;do not overcharge.

54-12 METERS AND GAUGES - Troubleshooting

TROUBLESHOOTINGOPERATION<Fuel gauge>l When the ignition key is at the “ON” position,

the fuel gauge is activated.l When there is much fuel, the unit’s resistance is

small and the current flowing in the circuit isgreat, so the gauge’s indicator indicates in the“F” area.

l When there is little fuel, the unit’s resistance ishigh and the current flowing in the circuit issmall, so the gauge’s indicator indicates in the“E” area.

<Engine coolant temperature gauge>l When the ignition key is at the “ON” position,

the engine coolant temperature gauge is acti-vated.

l When the engine coolant temperature is high,the unit’s resistance is low and there is a greatflow of current in the circuit, so the gauge’sindicaitor indicates in the “H” area.

l When the engine coolant temperature is low,the unit’s resistance is high and there is a smallflow of current in the circuit, so the gauge’sindicator indicates in the “C” area.

<Reed switch (NON-TURBO) / Speed sensor(TURBO)>l Pulses are produced in accordance with the

vehicle speed, and vehicle-speed signals areinput to systems (the MPI system, etc.) thatregulate according to the vehicle speed.

TROUBLIESHOOTING HINTS1. The fuel gauge doesn’t function, or shows the

incorrect indication.(1) Disconnect the connector of the fuel pump

and gauge unit assembly; the “F” side isi n d i c a t e d w h e n t e r m i n a l @ is thengrounded.l Check the fuel gauge.

2. The engine coolant temperature gauge doesn’tfunctilon, or shows the incorrect indication.(1) The “H” side is indicated when the connec-

tor of the engine coolant temperature gaugeunit is disconnected and then grounded.l Check the engine coolant temperature

gauge unit.

3. Syste’ms dependent upon control according tothe vehicle speed do not function correctly.l Check the reed switch (NON-TURBO)l Check the speed sensor (TURBO)

M54HHAS

<Oil pressure gauge>l When the ignition key is at the “ON” position,

the oil pressure gauge is activated.l When oil pressure is high, the internal contacts

of the gauge unit are kept closed for a longerperiod pf time. This causes more current to flowin the circuit, and the gauge pointer swings tothe high pressure side.

l When oil pressure is low, the internal contactsof the gauge unit. open in a shorter period oftime. Therefore, there is less current flowing inthe circuit and the gauge pointer swings to thelow pressure side.

<Pressure gauge (TURBO)>l When the ignition key is set to the “ON”

position, the gauge indicator will be at “0”.l When the engine is started, the indicator will

move from “0” to the minus (-) side, and then,as the boost level increases, it will move to theplus (+) side.

<Voltage gauge (NON-TURBO)>l When the ignition key is placed in the “ON”

position, the voltage gauge operates and indi-cates a battery voltage of approximately 12V.

l When the engine is started, the voltage gaugeindicates a battery voltage of 12 to 16V. indicat-ing that the battery is on charge.

NOTEFor operation of indicator and warning light, refer toP.54-30 INDICATORS AND WARNING LIGHTS.

4. The oil pressure gauge doesn’t function, orshows the incorrect indication.(1) The “H” side is indicated when the connec-

tor of the oil pressure gauge unit is discon-nected and then grounded.l Check the oil pressure gauge unit.

5. The meter illumination light does not illuminate.(1) The tail lights illuminate.

l Check the rheostat.

6. The voltage gauge doesn’t function, or showsthe incorrect indication.

l Check the voltage gauge.

OPERATION

i<Headlights ON operation>l On vehicles without a theft alarm system, when

the lighting switch is placed in the HEADposition with the ignition switch in the ACC orON position, current flows through the multi-purpose fuse @ to the coil of headlight relay, thelighting switch and ground, and causes thecontacts of the headlight relay to close, raisingthe headlights.On vehicles with a theft alarm system, when thelighting switch is placed in the HEAD position,current flows through the coil of the headlightrelay to the ETACS control unit, the lightingswitch and ground, and causes the contacts ofthe headlight relay to close, raising the head-lights.

l When the dimmer switch is placed in the LOposition, the headlight low-beams go on. Whenthe switch is placed in the HI position, theheadlight high-beams go on.

<Pop-up operation - Operation by lightingswitch>l When the lighting switch is placed in the HEAD

position, current flows through multi-purposefuse @ to the lighting switch, diode and ETACS

Lcontrol unit. Then the UP timer circuit in theETACS control unit is operated, and currentflows from the ETACS control unit to the Ucontact of the pop-up motor U/D (UP/DOWN)switch, the coil of the pop-up motor relay andground, causing the contacts of the pop-upmotor relay to close.When the contacts of the pop-up motor relayclose, current flows through the contacts of thepop-up motor relay to the pop-up motor andground, causing the pop-up motor to rotate,which brings the headlights to the UP position.The pop-up motor rotates until the automatic UPstop position is reached, then the contacts ofthe interlocked U/D (UP/DOWN) switch changefrom the U to D contacts. As a result, thecontacts of the pop-up motor relay open to cutoff the current supplied to the pop-up motor.Then the pop-up motor ceases to rotate, holdingthe headlights in the UP position.

l When the lighting switch is placed in the TAIL orOFF position, current flows through the multi-purpose fuse @ to the lighting switch, the diodeand the ETACS control unit. Then the DOWNtimer circuit in the ETACS control unit is oper-ated and current flows from the ETACS controlunit to the DOWN contacts of the pop-up motorU/D (UP/DOWN) switch, the coil of the pop-upmotor relay and ground, causing the contacts ofthe pop-up motor relay to close.When the contacts of the pop-up motor relayclose, current flows through the contacts of thepop-up motor relay to the pop-up motor andground, causing the pop-up motor to rotate,which brings the headlights to the DOWNposition.The pop-up motor rotates until the automaticDOWN stop position is reached, then thecontacts of the interlocked U/D (UP/DOWN)switch change from the D to U contacts. As aresult, the contacts of the pop-up motor relayopen to cut off current supply to the pop-upmotor. Then the pop-up motor ceases to rotate,holding the headlights in the DOWN position.

<Pop-up operation - Operation by pop-upswitch>l When the pop-up switch is placed in the UP

position, current flows through multi-purposefuse @to the lighting switch, the pop-up switchand the ETACS control unit, which brings theheadlights to the UP position and holds them inthe UP position just like when they are operatedby the lighting switch.

l When the pop-up switch is placed in the DOWNposition, current flows through the multi-purpose fuse @ to the lighting switch, thepop-up switch and the ETACS control unit,which brings the headlights to the DOWNposition and holds them in the DOWN positionjust like when they are operated by the lightingswitch.

<High-beam indicator light>l When the headlights are ON and in the high-beam position, or when the passing switch is placed in the

I

ON position, current flows through the contacts of the headlight relay to the dedicated fuse 0, ;i~thehigh-beam indicator light and ground, causing the high-beam indicator light to go ON, indicating that theheacllight high-beam are ON.

OPERATIONI’\J 1. Fhen operation .~s normal

When the rgnrtron switch is switched to theON position, battery voltage is applied (viathe multi-purpose fuse @and hazard switch)to the turn-signal and hazard flasher unit.

l When the turn-signal switch is switched tothe LH position, Trl (within the flasher unit)is switched ON and OFF repeatedly.Then the contacts of the relay 1 (also withinthe flasher unit) repeatedly switch from ONto OFF, causing the turn-signal lights andturn-signal indicator light LH to flash.

l When the turn-signal switch is switched tothe RH position, Tr2 (within the flasher unit)is switched ON and OFF repeatedly.Then the contacts of relay 2 (also within theflasher unit) repeatedly switch from ON toOFF, causing the turn-signal lights and turn-signal indicator light RH to flash.

2. If one of the bulbs is burned outl If the LH (or RH) turn-signal light bulb is

burned-out, the resistance of the turn-signalcircuit as a whole increases, resulting inshorter ON and OFF intervals of the LH Trl(or RH Tr2) and a higher flashing rate of theLH lights (or RH lights).

L

COMPONENTS LOCATION

<Hazard-warning lights>l When the hazard-warning switch is switched to

the “ON” position, the relay contact of the turnsignal and hazard flasher unit is switched ONand OFF repeatedly, in the same manner as forthe operation of the turn-signal lights, and theleft and right turn-signal lights and turn-signalindicator lights simultaneously flash repeatedly.

NOTEThe number of flashes of the hazard-warninglights does not change if there is damaged ordisconnected wiring of one light.

TROUBLESHOOTING H INTS1. The turn-signal lights and hazard-warning lights

do not operate at all.l Check the hazard switch contact (power

supply side).l Check the turn-signal and hazard flasher unit.

2. All turn-signal lights at the left (or right) side donot function.(1) The hazard-warning lights function normally.

l Check the hazard switch contact (turn-signal side).

l Check the turn-signal switch.

3. The number of flashes of the turn-signal lights isexcessive.l Check the bulbs.

Description of operationl Raising of Headlight

IWhen the pop-up switch is placed in the “UP” position or the lighting switch is placed in the “HEAD”position, transistor Tr of ECU is turned ON for 5 seconds to let current flow from the pop-up motor (coilside) to the ground through the U contacts of the U/D (UP/DOWN) switch for the pop-up motor, closingthe contacts of the pop-up motor relay to raise the headlights. When the crank arm attached to the pop-upmotor comes to the automatic up stop position, the contacts of the U/D (UP/DOWN) switch change fromthe U contacts to the D contacts. Therefore, the current flowing to the pop-up motor is interrupted,stopping the pop-up motor and leaving the headlight at the UP position.

l Lowering of Headlight

When the pop-up switch is placed in the “DOWN” position or the lighting switch is placed in the “OFF” or“TAIL” position, transistor Tr of ECU is turned ON for 5 seconds to let current flow from the pop-up motorrelay (coil side) to the ground through the D contacts of the U/D (UP/DOWN) switch for the pop-up motor.The pop-up motor relay (contact side) will be closed, lowering the headlight. When the crank arm attachedto the pop-up motor comes to the automatic down stop position, the contacts of the U/D (UP/DOWN)switch change from the U contacts to the D contacts. Therefore, the current flowing to the pop-up motoris interrupted, stopping the pop-up motor and leaving the headlight at the DOWN position.

NCjTEAbout FM waves:FM waves have the same properties as light, andcan be deflected and blocked. Wave reception is notpossible in the shadow of obstructions such asbuildings or mountains.1. The signal becomes weak as the distance from

the station’s transmission antenna increases.Although this may vary according to the signal

strength of the transmitting station and interven-ing geographical formations or buildings, thearea of good reception is approx, 20 - 25 km (12- 16 miles) for stereo reception, and 30 - 40 km(19 - 25 miles) for monaural reception.

2. The signal becomes weak when an area ofshadow from the transmitting antenna (placeswhere there are obstructions such as mountainsor buildings between the antenna and the car),

and noise will appear. <This is called first fading,and gives a steady buzzing noise.>

3. If a direct signal hits the antenna at the sametime as a signal reflected by obstructions suchas mountains or buildings, interference of thetwo signals will generate noise.During traveling,noise will appear each time the vehicle’s anten-na passes through this kind of obstructed area.The strength and interval of the noise variesaccording to the signal strength and the condi-tions of deflection. <This is called multipathnoise, and is a repetitious buzzing.>

4. Since FM stereo transmission and reception hasa weaker field than monaural, it is often accom-panied by a hissing noise.

This suppresses noiseby grounding the noise component (A.C. orpulse signal) to the body of the vehicle.CoilThe coil passes D.C. current, but impedancerises as the number of waves increases relativeto the A.C. current. A noise suppressing coilwhich takes advantage of this property is in-serted into the power line for the noise source,and works by preventing the noise componentfrom flowing or radiating out of the line.

* About multipath noise and fading noiseBecause the frequency of FM waves is extreme-ly high, it is highly susceptible to effects fromgeological formations and bui1ding.s. Theseeffects disrupt the broadcast signal and obstructreception in several ways.

l Multipath noiseThis ‘describes the echo that occurs when thebroadcast signal is reflected by a large obstruc-

tion and enters the receiver with a slight timedelay relative to the direct signal (repetitiousbuzzing).

l Fading noiseThis is a buzzing noise that occurs when thebroadcast beam is disrupted by obstructingobjects and the signal strength fluctuates intri-cately within a narrow range.
