ECD SYSTEM REGISTRATION


  1. LEARNING VALUES CONFIRMATION

    This procedure uses the GTS to display the learned values (injector compensation code, pilot quantity initial learning value, pilot quantity deterioration learning value, pilot quantity current learning value, pilot quantity learning value, crank time compensation learning value, A/F sensor learning value and catalyst deterioration learning value) stored in the ECM.

    Tech Tips


    • When replacing the engine assembly, injector assembly together with the ECM, this function automatically determines the data which can be transferred (old data) and saves the data in the GTS.

    • A003AL0

      When there is no data to read from the ECM, manually perform the procedure to register each compensation code and learning value in the ECM.

    • A003ESV

      A malfunction may occur when reading the values if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

  4. AFTER REPLACING INJECTOR(S) WITH NEW ONE(S), INPUT COMPENSATION CODE(S) OF INJECTOR(S) INTO ECM AS FOLLOWS:

    Note


    • 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.

    • 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.

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

    12. A003CKG

      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.

      Note

      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.

      Tech Tips

      If a wrong compensation code was input or read, return to the input Value screen by pressing input. 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.
