Test A: The Air Bag Warning Indicator Illuminated Continuously-RCM Disconnected/Inoperative-Loss of Battery Feed/signal ground

PINPOINT TEST A: THE AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLY - RCM DISCONNECTED OR INOPERATIVE, LOSS OF BATTERY FEED OR LOSS OF SIGNAL GROUND

Normal Operation
During normal operation, the air bag indicator will illuminate continuously for approximately 6 seconds and then go out after the ignition switch is placed in the ON or START position and no air bag faults exist. The air bag indicator will remain illuminated continuously after 3 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 AG to troubleshoot the system. Tests AG: No Communication With The Restraints Control Module (RCM)

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