Test A3-A5:

Test 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 using 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 could be caused by:
- circuitry.
- the ignition circuit damaged.
- the RCM disconnected from the vehicle harness.
- a loss of RCM ground circuit.
- the RCM inoperative.
- a faulted shorting bar or camming beam in connector.
