ECD SYSTEM REGISTRATION

Note


  • When an injector assembly is replaced, the injector's compensation code must be input into the ECM (Proceed to step 1).

  • When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM (Proceed to step 2).


  1. INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

    Note


    • Injector compensation codes are printed on the head portion of each injector assembly. If an incorrect injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough. In addition, an engine failure may occur and the life of the engine may be shortened.

    • Although some injectors are marked with a 32-digit alphanumeric value, only the first 30 digits must be input.


    1. Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.

      Note

      Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.
