DESCRIPTION

DTC Detection Condition:

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

The D-4S system has two fuel injection methods. One is the in-cylinder direct injection method that directly injects pressurized fuel into the combustion chamber. The other is the intake port injection method. The ECM determines which fuel injection method to use in accordance with the engine conditions. For the in-cylinder direction injection method, the 2 injector drivers (EDU) in the engine room operate the fuel injectors (for direction injection) at high speeds.

Each EDU receives fuel injection request signals from the ECM and converts the signals to high voltage / high current injector operation signals to operate the fuel injectors (for direction injection). The fuel injection sequence occurs in the following order: No.1, No. 8, No. 7, No. 3, No. 6, No. 5, No. 4, No.2.

The ECM monitors each EDU at all times. If drivers or injectors are malfunctioning, the EDU sends fuel injector operation condition fail signals (INJ1 to INJ4) to the ECM. When the ECM receives the signals, the ECM stops the fuel injection control of the appropriate cylinders, cuts voltage to the appropriate INJ relay, and illuminates the MIL.

INSPECTION PROCEDURE

HINT: Read freeze frame data using the intelligent tester or Techstream. 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.
