Test A

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

Test A1-A3:

Test A3-A4:

Test A4-A6:

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 fault exist. The air bag indicator will remain illuminated continuously after five cycles of a lamp fault code (LFC), if a fault exist.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 scan tool through the data link connector (DLC). If the scan tool displays NO COMMUNICATION when retrieving continuous DTCs, GO to Pinpoint Test Y to troubleshoot the system. Test Y

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