HIACE (EWD622E)


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

1. Input Signals

(1) Water temp. signal circuit

The water temp. sensor (Engine coolant) detects the engine coolant temp. and has a built–in thermistor with aresistance varies according to the engine coolant temp. Thus the engine coolant temp. is input in the form of a controlsignal to TERMINAL THW of the engine ECU.

(2) Intake air temp. signal circuit

The intake air temp. sensor is detects the intake air temp., which is input as a control signal to TERMINAL THA of theengine ECU.

(3) RPM signal circuit

Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.Camshaft position is input as a control signal to TERMINAL G1 of the engine ECU, and engine RPM is input intoTERMINAL NE+.

(4) Throttle signal circuit

The accelerator position sensor detects the accelerator pedal opening angle, which is input as a control signal toTERMINALS VPA and VPA2 of the engine ECU.

(5) Vehicle speed signal circuit

The speed sensor detects the vehicle speed and inputs a control signal to TERMINAL SPD of the engine ECU via thecombination meter.

(6) Battery signal circuit

Voltage is constantly applied to TERMINAL BATT of the engine ECU. When the ignition SW is turned to on, voltage forengine ECU operation is applied via the MAIN relay to TERMINAL +B of the engine ECU.

(7) Started signal circuit

To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input asa control signal to TERMINAL STA of the engine ECU.

(8) Fuel temp. signal circuit

The fuel temp. sensor is detects the fuel temp., which is input as a control signal to TERMINAL THF of the engine ECU.

(9) Intake air vacuum pressure signal system

Intake air vacuum pressure is detected by the turbo pressure sensor and is input as a control signal to TERMINAL PIMof the engine ECU.

2. Control System

∗ EGR controlThe EGR control system detects the signals from each sensor, then the current is output to the TERMINAL EGR to controlthe VRV (EGR).

∗ Common rail pressure controlThe target rail pressure is calculated according to the engine status (Accelerator opening, engine speed) andenvironmental change detected by sensors. The fuel amount to be pressure–fed from the supply pump is calculated so asto match the indicated value of rail pressure sensor with the target value and the signal is sent to the intake amountadjusting valve of the supply pump in order to control the rail pressure.

∗ Fuel injection timing controlThe fuel injection timing is controlled by calculating the basic fuel injection timing based on the engine status (Acceleratoropening, engine speed), making corrections according to environmental change detected by sensors, then sending asignal to the solenoid control valve of the injector via the injector driver (EDU).

∗ Fuel injection volume controlThe fuel injection volume is controlled by calculating the basic fuel injection volume based on the engine status(Accelerator opening, engine speed), making corrections according to environmental change detected by sensors and theinside pressure conditions in the rail, then sending a signal to the solenoid control valve of the injector via the injectordriver (EDU).

∗ Pilot injection controlThe fuel injection volume and timing are controlled by calculating the pilot injection volume/timing based on the engine

status (Accelerator opening, engine speed), making corrections according to environmental change detected by sensors,then sending a signal to the solenoid control valve of the injector via the injector driver (EDU).

3. Diagnosis System

With the diagnosis system, when there is a malfunctioning in the engine ECU signal system, the malfunction system isrecorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warninglight.

4. Fail–Safe System

When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control basedon the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded inthe engine ECU memory or else stops the engine.
