DESCRIPTION

The D-4S (Direct injection 4-stroke gasoline engine superior) has two fuel injection systems. One is the port fuel injection. The other is the direct fuel injection.

In the direct fuel injection system, the injector driver operates the fuel injector (for Direct Injection) using DC 50 V. This voltage is built up by the internal DC-DC converter of the injector driver. The engine control module (ECM) controls the injector driver according to the engine conditions.

The two injector drivers are used to control this engine. The No. 1 injector driver operates the direct fuel injectors #1, #4, #6, #7. The No. 2 injector driver operates the direct fuel injectors #2, #3, #5, #8.

MONITOR DESCRIPTION

The injector driver sends the injection confirmation signal (INJ) to the engine control module (ECM). Using this signal, the ECM monitors the direct fuel injector operation. If the ECM receives no INJ signal in 20 consecutive engine rotations, illuminates the MIL and sets the DTC immediately. Then, the ECM aborts the direct fuel injection of the appropriate cylinder, or turns off the EDU relay to shut the injector driver power source.

CAUTION / NOTICE / HINT

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. INSPECT INJECTOR DRIVER (POWER SOURCE OF ECU)


    1. Disconnect the E16 or E28 injector driver (EDU) connector.

      Note

      Do not disconnect the connectors while the engine is running.

    2. Turn the Power switch on (IG).

      Note


      • If DTC P062D or P062E is detected, the inspection cannot be performed. Therefore, clear the DTCs, and then turn the power switch on (IG).

      • Do not turn the power switch on (READY) after clearing the DTCs.
