ECD SYSTEM(w/o DPF) PRECAUTION


  1. INITIALIZATION AND REGISTRATION

    Note

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

    Tech Tips

    When the ECM and one or more other components 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. FUEL INJECTOR COMPENSATION CODE


    1. Each fuel 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 fuel injector according to its compensation code. Fuel injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion of each fuel injector.

    2. A01X5Z4E09
      Example
      *1 Fuel Injector Compensation Code

      When a fuel injector is replaced, the new fuel injector compensation code must be input into the ECM.

    3. When the ECM is changed, all of the existing fuel injector compensation codes must be input into the new ECM.

    4. 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. FOR USING GTS

    CAUTION:


    • Observe the following items for safety reasons:


      • Before using the GTS, read its instruction manual.

      • Prevent the EGR cable from being caught on the pedals, shift lever or steering wheel when driving with the EGR connected to the vehicle.

      • When driving the vehicle for testing purposes using the EGR, two persons are required. One person drives the vehicle, and the other operates the EGR.

  4. IGNITION SWITCH EXPRESSION

    Tech Tips

    The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this section.

    Expression Ignition Switch (position) Engine Switch (condition)
    Ignition Switch off Off Off
    Ignition Switch ON ON On (IG)
    Ignition Switch ACC ACC On (ACC)
    Engine Start START Start
