Normal Operation

NOTE: Be sure to cycle the ignition switch and look for a 6 second indicator prove-out without LFCs.

During normal operation the air bag indicator will illuminate 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. 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 DTCs, GO to Pinpoint Test U to troubleshoot the system. Test U: No Communication With the Restraints Control Module

Possible Causes
An air bag indicator that is illuminated continuously can be caused by one of the following:
^ Wiring, terminals, or connectors.
^ The ignition circuit damaged.
^ The RCM disconnected from the vehicle harness.
^ A loss of RCM battery feed.
^ A loss of RCM signal ground.
^ Worn or damaged shorting bar or camming beam.
^ RCM is faulted.
