Diagnostic Procedures

  1. If QUICK TEST was not performed, go to QUICK TEST  under SELF-DIAGNOSTIC SYSTEM. If QUICK TEST was performed, go to next step.
    NOTE: DTC P1000 indicates that all OBD II monitors have not yet been successfully tested to clear DTC P1000.

  2. DTC P1000: Check For Other DTCs

    Test should be used only if DTC P1000 was received in Continuous Memory. Ignore any DTC P1000s in KOEO or KOER. If no other DTCs were received with P1000, go to next step. If any other DTCs were received with P1000, repair those DTCs first. Refer to DIAGNOSTIC TROUBLE CODE DEFINITIONS .

  3. Request To Clear DTC P1000

    If customer has requested DTC P1000 be cleared from PCM memory, go to next step. If customer has not requested DTC P1000 be cleared from PCM memory, inform customer that if the law in this state requires additional driving in order to clear DTC P1000 from PCM memory, it must be performed before an inspection/maintenance test.

  4. Verify Trouble Shooting Of DTCs Completed

    Reconnect all disconnected connectors. Clear DTCs from PCM memory using scan tool. Perform QUICK TEST  under SELF-DIAGNOSTIC SYSTEM. If same DTC is present, replace faulty PCM. Repeat QUICK TEST  under SELF-DIAGNOSTIC SYSTEM. If same DTC is not present, go to applicable procedure for other DTCs. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no DTCs are present, trouble shooting is complete.
