СИСТЕМА ECD РЕГИСТРАЦИЯ

CAUTION / NOTICE / HINT

Tip:
  • 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.

PROCEDURE

  1. LEARNING VALUES CONFIRMATION

    Tip:

    This function is used for reading learning values that are input correctly.

    A012K3CE01
    Tip:

    This 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.

    Tip:

    This 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.

    A012N52
    Tip:

    If the saved data cannot be written into a new ECM for some reason, input the vehicle mileage to the ECM using the "Vehicle Mileage Write" function.

    A012JT3

  4. INJECTOR COMPENSATION

    A012J20C01
    *a Example
    *b Injector Compensation Code
    Note:

    Injector compensation codes are 12-digit, alphanumeric values printed on the head of each injector. If an incorrect 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.

    A012L6LE05
    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

      Tip:

      Confirm that the ignition switch is ON and the engine is stopped.

    3. Enter the following menus: Powertrain / Engine and ECT / Utility / Injector Compensation.

      Powertrain > Engine and ECT > Utility
      Tester Display
      Injector Compensation
    4. Press "Next".

      A012MKS
    5. Press "Next".

      A012KPW
    6. Press "Next".

      A012IDO
    7. Select the number of the cylinder corresponding to the injector compensation code that you want to input, and press "Next".

      A012IR9
    8. Register the compensation code.

      1. Press "Input".

        A012FJ1
      2. 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.

        A012LZK
        Tip:

        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. 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.

      A012MPV
      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.

      Tip:
      • 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.

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

      A012JRO
    12. Turn the ignition switch off and turn the GTS off.

    13. Wait for at least 30 seconds.

    14. Turn the ignition switch to ON and turn the GTS on.

    15. Clear the DTC P0603 stored in the ECM using the GTS.

      Powertrain > Engine and ECT > Clear DTCs
  5. VEHICLE MILEAGE WRITE

    Tip:

    If Pilot Quantity Learning Values and DPF Deterioration Record cannot be saved or written using the GTS, the ECM estimates the Pilot Quantity Learning Values and DPF Deterioration Record based on the traveled distance using this function.
