NOTICE:
  1. When an injector is replaced, the injector's compensation code must be input into the ECM. When the ECM is replaced, all of the existing injector compensation codes must be input into the new ECM.
  2. Injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion of each injector. If an incorrect injector compensation code is input into the ECM, the engine assembly may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch ON.

  1. Turn the tester ON.

    NOTICE:
    Do not start the engine.
    HINT:
    The injector compensation code is printed on the head portion of each injector.

    2. Manually input the cylinder's compensation code using the keyboard on the tester screen. The code is a 30 digit, alphanumeric value printed on the injector's head portion.

      HINT:
      Each injector compensation code is unique. The correct compensation code must be input into each cylinder selected on the tester.

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



    Toyota Fortuner. Ggn50, 60 Kun51, 61 Tgn51 Lan50.1Kd-Ftv Engine Control System.Ecd System.Ecd System Registration

  1. Check that the compensation code displayed on the screen is correct by comparing it with the 30 digit alphanumeric value on the head portion of the injector.

    NOTICE:
    If an incorrect injector compensation code was 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.
    HINT:
    1. If a wrong compensation code was input or read, return to the Input Value screen by pressing Input.
    2. 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 the DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and repeat this operation.

  1. Press Next to set the compensation code to the ECM.

    HINT:
    1. If the setting process fails, the compensation code may be incorrect. Check the compensation code again.
    2. If the input compensation code is correct, a problem with the wire harness or a bad connection with the DLC3 may cause the failure. Check the wire harness and the DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and restart this operation.

2. WHEN REPLACING ECM WITH A NEW ONE, INPUT ALL INJECTOR COMPENSATION CODES INTO NEW ECM AS FOLLOWS:
NOTICE:
  1. When an injector is replaced, the injector's compensation code must be input into the ECM. When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM.
  2. Injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion 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.
