ECD SYSTEM(w/ Glow Plug Controller) REGISTRATION

CAUTION / NOTICE / HINT

Note

The Vehicle Identification Number (VIN) or frame number must be written 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 No. 2 exhaust manifold, perform the "DPF Deterioration Record Clear" function using the GTS. If the No. 2 exhaust manifold 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, input manually 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 or Frame Number and Write VIN or Frame Number.


    1. Read VIN or Frame Number: This process allows the VIN or frame number stored in the ECM to be read in order to confirm that the VINs or frame numbers, provided on the vehicle body and stored in the vehicle ECM, are the same.

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

  2. READ VIN OR FRAME NUMBER


    1. Confirm the vehicle VIN or frame number.

    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.


      Powertrain > Engine and ECT > Utility
      Tester Display
      VIN

    6. According to the display on the GTS, read the frame number or VIN stored in the ECM.

  3. WRITE VIN OR FRAME NUMBER


    1. Confirm the vehicle VIN or frame number.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

  7. INJECTOR COMPENSATION

    A01M22TC02
    *a Example
    *b Injector Compensation Code

    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.

    A01LZ6AE05

    1. Connect the GTS to the DLC3.

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

      Tech Tips

      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. A01M389

      1. A01LYDW

        Press "Input".

      2. A01M31I

        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. A01LYGO

      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.

    11. A01LXVU

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

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