ECD SYSTEM(w/ DPF) REGISTRATION

CAUTION / NOTICE / HINT

Note

The Vehicle Identification Number (VIN) must be input into a replacement ECM.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations 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/registrations 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/registrations as when replacing the ECM.

  • After replacing the exhaust manifold assembly, perform the "DPF Deterioration Record Clear" function using the GTS. If the exhaust manifold assembly and the ECM are replaced at the same time, perform the same initialization/registrations 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/registrations as when replacing the ECM.

  • If the "Learning Values Save" or "Learning Values Write" function has failed, manually input the injector 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. DESCRIPTION

    Tech Tips

    This registration section consists of 2 parts: Read VIN and Write VIN.


    1. Read VIN: This process allows the VIN stored in the ECM to be read in order to confirm that the 2 VINs, provided with the vehicle and stored in the vehicle ECM, are the same.

    2. Write VIN: This process allows the VIN to be input into the ECM. If the ECM is replaced, or the ECM VIN and vehicle VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.

  2. READ VIN


    1. Confirm the vehicle VIN.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the GTS on.

    5. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Read.

  3. WRITE VIN


    1. Confirm the vehicle VIN.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the GTS on.

  7. INJECTOR COMPENSATION

    A01VJ9EE01

    Note

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

      1. A01VIVX

        Press "Input".

      2. A01VKP9

        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. A01VEUJ

      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 injector assembly.

      Note

      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.

      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.
