Toyota Fortuner. Ggn50, 60 Kun51, 61 Tgn51 Lan50.2Kd-Ftv Engine Control System.Ecd System.Ecd System Registration
NOTICE:
  1. When a fuel injector is replaced, the new fuel injector compensation code must be input into the ECM. When the ECM is replaced, all of the existing fuel injector compensation codes must be input into the new ECM.
  2. Fuel injector compensation codes are unique, 30-digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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.
  3. When a fuel injector compensation code is input into the ECM, the pilot quantity learning values stored in the ECM are initialized. Also, DTC P1601 is stored when the pilot quantity learning values are initialized.

Injector Compensation Code

  1. After replacing fuel injector(s) with new one(s), input compensation code(s) of the fuel injector(s) into the ECM as follows:

    HINT:
    1. Each fuel injector has different fuel injection characteristics. In order to optimize the fuel injections, the ECM uses the compensation codes to balance the different fuel injections between each fuel injector.
    2. When only one or more fuel injectors are replaced, input the fuel injector compensation code(s), perform pilot quantity learning, and then clear the DTCs.
    3. When the ignition switch is turned to ON after replacing the ECM, DTC P1601 is stored. This indicates that the fuel injector compensation code(s) need to be registered. Manually clear the DTC upon completion of pilot quantity learning.

    1. Input the compensation code(s), which is/are imprinted on the head portion(s) of the new fuel injector(s), into the intelligent tester.

    2. Input the new compensation code(s) into the ECM using the tester.

    3. Turn the tester off and turn the ignition switch off.

    4. Wait for at least 30 seconds.

    5. Turn the ignition switch to ON and turn the tester on.

    6. Perform pilot quantity learning.

    7. Clear the DTC P1601 stored in the ECM using the tester (Toyota Fortuner RM000000PDK0TWX.html).

      NOTICE:
      If the DTCs are cleared without performing pilot quantity learning, DTC P1601 is stored the next time the ignition switch is turned to ON.

      HINT:
      1. If the registration process fails, the compensation code may be incorrect. Check the compensation code again.
      2. 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.
