    Tech Tips

    When the exhaust manifold converter sub-assembly is replaced, the catalyst record of DPF thermal deterioration stored in the ECM must be cleared.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the menu options in this order: Powertrain / Engine and ECT / Utility / Catalyst Record Clear.

    9. Press "Exit".

  3. CRANK TIME COMPENSATION RESET FUNCTION


    • This procedure uses the GTS to perform "Crank Time Compensation Reset".

    • When replacing the crankshaft, perform "Crank Time Compensation Reset".

    Tech Tips


    • A003F6E

      If an error occurs during compensation reset, check the vehicle condition, and then perform compensation reset again.

    • A communication malfunction may occur 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.


    1. Connect the GTS to the DLC3.
