DESCRIPTION

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 in the engine room operate the fuel injectors (for direct injection) at high speeds.

Each injector driver 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 direct 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 injector driver at all times. If drivers or injectors are malfunctioning, the injector driver 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

Tech Tips

If the current from the INJ relay is cut because DTC P062D is stored, DTC P1235 will be stored even if the fuel pump for high pressure (Bank 1) is normal.
If the current from the INJ2 relay is cut because DTC P062E is stored, DTC P1236 will be stored even if the fuel pump fir high pressure (Bank 2) is normal.
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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

CLEAR DTC
1. Connect the intelligent tester to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the tester on.
4. Clear the DTCs Click here.
  Tech Tips
  - If DTC P062D is stored, current to the INJ relay will be shut off.
  - If DTC P062E is stored, current to the INJ2 relay will be shut off.
