Diagnostic Test

1. Testing should only be performed with the battery fully charged to avoid false diagnosis.
2. With the scan tool, read Engine (PCM) DTCs. If Engine DTCs are present, refer to the Engine Category and perform the appropriate diagnostic procedure(s) before proceeding.
3. With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information. Diagnose any Pending DTC as a matured DTC.
4. Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving under specific conditions, or after controller diagnostic monitors have run.
5. Refer to applicable Technical Service Bulletins (TSBs) for controller software update information. Some conditions can be corrected by upgrading the Engine (PCM) or Transmission (TCM) controller software.
6. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
