Normal Operation

NOTE: Be sure to cycle the ignition switch and look for a 6 second indicator prove-out without LFCs.

During normal operation, the air bag indicator will illuminate continuously for approximately six seconds and then go out after the ignition switch is placed in the ON or START position and no air bag fault exists. The air bag indicator will remain illuminated continuously after five cycles of a lamp fault code (LFC), if a fault exists. Be sure to cycle the ignition switch and look for an approximate 6 second indicator prove-out without LFCs.

The restraints control module (RCM) will communicate diagnostic trouble codes (DTCs) to the diagnostic tool through the data link connector (DLC). If the diagnostic tool displays NO COMMUNICATION when retrieving continuous DTCs, GO to Pinpoint Test Y to troubleshoot the system. Test Y: No Communication With The Restraints Control Module (RCM)

Possible Causes
An air bag indicator that is illuminated continuously can be caused by one of the following:
- damaged ignition circuit
- RCM disconnected from the vehicle harness
- a loss of RCM signal ground
- a faulted RCM
- damaged wiring, terminals, or connectors
- a loss of RCM ignition feed
- a faulted instrument cluster module
