Post Failure
NOTE:
After making any repairs, perform BODY VERIFICATION TEST
under VERIFICATION TESTS.
- Connect scan tool to Data Link Connector (DLC), under lower left side of instrument panel. Turn ignition on. Using scan tool, erase Central Timer Module (CTM) DTCs. Cycle ignition off, and then on and wait approximately one minute. Using scan tool, read CTM DTCs. If POST FAILURE DTC resets, go to next step. If POST FAILURE DTC does not reset, problem is intermittent. Visually inspect and wiggle test related wiring.
- Replace CTM. CTM is located behind left side kick panel. See CENTRAL TIMER MODULE under REMOVAL & INSTALLATION.
