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

A1-A3:

A4-A7:

NOTE: During normal operation, the air bag indicator will illuminate continuously for 6 seconds after the ignition switch is placed to the RUN or ON position. Be sure to cycle the ignition switch and look for a 6-second indicator prove-out without DTCs.

Normal Operation
The restraints control module (RCM) will communicate diagnostic trouble codes (DTCs) to the scan tool through the data link connector (DLC). If the scan tool displays NO COMMUNICATION when retrieving continuous DTCs, refer to Information Bus (Module Communications Network) to diagnose the no communication concern.

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