NOTE:
After making any repairs, perform BODY CONTROL MODULES SYSTEM VERIFICATION TEST
under VERIFICATION TESTS.
Turn ignition off. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, clear DTCs. Turn ignition off, then on. Using scan tool, retrieve DTCs. If POST FAILURE DTC resets, replace BCM. If POST FAILURE DTC does not reset, fault may be intermittent. Check related wiring and connectors for poor connections or damage to wiring harness. See WIRING DIAGRAMS . Repair any problems found as necessary. If no problems are found, check if any Technical Service Bulletins (TSBs) apply to vehicle. If no TSBs apply, test is complete.
