Test A: Air Bag Warning Light On Continuously-RCM Disconnected, Inoperative Or Lost/Low Ignition Feed: Description
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
During normal operation, the AIR BAG warning light will be continuously illuminated for 6 seconds after the ignition switch is placed in RUN position and after 5 cycles of Light Flash Code (LFC) if a fault exists. Be sure to cycle ignition switch and look for a continuous AIR BAG warning light without LFC.
Restraints Control Module (RCM) will communicate Diagnostic Trouble Codes (DTCs) through scan tool using Data Link Connector (DLC). If scan tool displays NO COMMUNICATION when retrieving continuous codes, go to TEST Y: NO COMMUNICATION WITH RCM .
