  4. INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

    A01DVCUE01

    Note


    • 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.

    • 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.

    • When a fuel injector compensation code is input into the ECM, the pilot quantity learning values stored in the ECM are initialized. Also, DTC P062F is stored when the pilot quantity learning values are initialized.

    Text in Illustration
    *a Example
    *b 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:

      Tech Tips


      • 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.

      • 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.

      • When the ignition switch is turned to ON after replacing the ECM, DTC P062F 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.
