Test A: The Air Bag Warning Indicator Is Illuminated Continuously

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:

A3-A6:

A7:

NOTE: During normal operation, the air bag indicator will illuminate continuously for 6 seconds after the ignition switch is placed in the RUN or ON position and after 3 cycles of a lamp fault code (LFC) if a fault exists. Be sure to cycle the ignition switch and look for a 6-second indicator prove-out without LFCs.

Normal Operation
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 AO to troubleshoot the system. Tests AO: No Communication With the Restraints Control Module (RCM)

Possible Causes
An air bag indicator that is illuminated continuously can be caused by:
- 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.
- RCM is faulted.
