СИСТЕМА ECD (для моделей без контроллера свечей накаливания) РЕГИСТРАЦИЯ

CAUTION / NOTICE / HINT

Tech Tips


  • Before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • After replacing any of the injector assemblies, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the GTS. If any of the injector assemblies and the ECM are replaced at the same time, perform the same initialization and registration procedures as when replacing the ECM.

  • After replacing the air fuel ratio sensor, perform the "A/F Sensor Compensation Reset" function using the GTS. If the air fuel ratio sensor and the ECM are replaced at the same time, perform the same initialization and registration procedures as when replacing the ECM.

  • After replacing the DPF catalytic converter, perform the "DPF Deterioration Record Clear" function using the GTS. If the DPF catalytic converter and the ECM are replaced at the same time, perform the same initialization and registration procedures as when replacing the ECM.

  • After replacing the engine assembly, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the GTS. If the engine assembly and the ECM are replaced at the same time, perform the same initialization and registration procedures as when replacing the ECM.

  • If the "Learning Values Save" or "Learning Values Write" function has failed, manually input the injection compensation codes and the vehicle mileage using the "Injector Compensation" and "Vehicle Mileage Write" functions by following the instructions shown on the GTS display.

      1. A00YAM4

        Press "Input".

      2. A00Y7TW

        Manually input the cylinder compensation code using the keyboard on the GTS screen. The code is a 12-digit, alphanumeric value printed on the injector head.

        Tech Tips

        The compensation code for each selected cylinder must be input into the GTS correctly.

      3. Confirm that the compensation code for the selected cylinder is correct, and then press OK.

    9. A00Y5MS

      Check that the compensation code displayed on the screen is correct by comparing it with the 12-digit alphanumeric value on the head of the fuel injector.

      Note

      If an incorrect fuel injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

      Tech Tips


      • If a wrong compensation code is input or read, return to the Input Value screen by pressing Input.

      • The saving process may fail due to a problem with the wire harness or a bad connection with the DLC3. Check the wire harness and DLC3 connection. If no problem is found with either, the ECM may be malfunctioning.

    10. Press Next to register the compensation code in the ECM.

      Tech Tips


      • If the registration process fails, the compensation code may be incorrect. Check the compensation code again.

      • If the input compensation code fails to register even though it is input correctly, there may be a problem with the wire harness or a bad connection with the DLC3. Check the wire harness and DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and restart this operation.

    11. A00Y7N3

      If you want to continue with other compensation code registrations, press "Next". To finish the registration, press "Exit".
