Test A
PINPOINT TEST A: THE AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLY - RCM DISCONNECTED, INOPERATIVE, OR LOST/LOW IGNITION FEEDA1 - A2:
A3 - A4:
A5 - A7:
Normal Operation
NOTE: During normal operation the air bag indicator will be lit continuously for 6 seconds after the ignition switch is placed in the RUN position and after five 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.
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 P to troubleshoot the system. Test P
Possible Causes
An air bag indicator that is illuminated continuously can be caused by one of the following:
- worn or damaged shorting bar or camming beam.
- the ignition circuit damaged.
- the RCM disconnected from the vehicle harness.
- a loss of RCM ground circuits.
- the RCM inoperative.
- circuitry.
