Normal Operation

NOTE: During normal operation, the air bag indicator will illuminate continuously for 6 seconds after the ignition switch is placed to the ON or START 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 U to troubleshoot the system. Test U
