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. The air bag indicator will also illuminate 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 continuous DTCs, use Pinpoint Test AL to troubleshoot the system.
Possible Causes
An air bag indicator that is illuminated continuously can be caused by:
^ a damaged shorting bar or other electrical connector component.
^ the ignition circuit damaged.
^ the RCM disconnected from the vehicle harness.
^ a loss of RCM ground circuit.
^ the RCM is faulted.
^ air bag indicator circuit shorted to ground.
