NOTE:
After making any repairs, perform BODY VERIFICATION TEST under VERIFICATION TESTS.
- Turn ignition on. Using scan tool, attempt to communicate with Sentry Key Immobilizer Module (SKIM). If scan tool communicates with SKIM, go to next step. If scan tool does not communicate with SKIM, go to BUS +/- SIGNALS OPEN FROM SENTRY KEY IMMOBILIZER MODULE .
- Using scan tool, erase DTCs. Turn ignition off and on. Wait a minimum of one minute. Using scan tool, check for DTCs. If DTC resets, replace Body Control Module (BCM). See BODY CONTROL MODULE under REMOVAL & INSTALLATION. If DTC does not reset, testing is complete.
