Monitor DTC Status

  1. Plug GDS to Data Link Connector (DLC).
  2. Turn "ON" the ignition switch and start the engine.
  3. Warm up the engine to the normal operating temperature.
  4. Read the "DTC State" parameter.

    Clear the DTC and see if the same DTC returns.

  5. Is the DTC State "Present"?

    YES 

    • Replace the AWD ECM with an usable one and check for proper operation. If the problem is corrected, replace the AWD ECM.
    • Repair or replace the relevant component(s) as necessary, and go to "VERIFICATION OF VEHICLE REPAIR ".

      * After replacing the AWD ECU, perform the "Back-up and enter the 4WD learnt value_ECU replacement" on the optional menu.

    NO 

    • The fault can be intermittent. Or, the AWD system's memory was not cleared after repair. Clear the DTC and go to "VERIFICATION OF VEHICLE REPAIR ".
