  1. INITIALIZATION AND REGISTRATION

    Note:

    When replacing the ECM and/or any other components in the following chart, perform the corresponding utility items.

    Tip:

    When the ECM and other component(s) are replaced at the same time, perform the following utility items by following the instructions shown on the GTS display, starting with the ECM.

  2. INJECTOR COMPENSATION CODE

    Tip:

    • Each injector has different fuel injection characteristics. In order to optimize fuel injection performance, the ECM compensates for these differences by adjusting the fuel injection duration of each injector according to its compensation code. 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.
