Self-Diagnostic System: Notes

NOTE: Vehicles with analog instrument panel cluster are equipped with a Climate Control Panel (CCP). Vehicles with digital instrument panel cluster are equipped with a Climate Control Center (CCC). References to CCP also include CCC.

Body Control Module (BCM) is equipped with a self-diagnostic system, which detects system failures or abnormalities. When a malfunction occurs, BCM will store a 5-digit alphanumeric code.

After BCM trouble codes have been displayed, service mode can be used to clear codes and exit diagnostics or individually perform other tests on different systems. To continue with system diagnostics, see SERVICE MODE OPERATION. To exit diagnostic mode, press DEFOG or MODE button on CCP, or turn ignition off. Codes will not be cleared. System will return to normal vehicle operation.
