Check For Short To Ground

WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford F-Super Duty, 1995 Ford Cab & Chassis, and 1995 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.

Inspect circuits No. 623, 614, 615, 617, and 619 for short to ground. Inspect wiring harness areas where wires pass through or are located next to metal components. Repair as necessary. AFTER repair is completed, check AIR BAG warning light for codes. If Code 51 exists, deactivate air bag system. See COMPLETE SYSTEM DEACTIVATION  under DISABLING & ACTIVATING AIR BAG SYSTEM. Replace diagnostic monitor.

NOTE: Code 51 is displayed whenever diagnostic monitor thermal fuse is open and no other higher priority faults exist. Code 51 is normally seen after service of a Code 13 condition. If a Code 51 exists and a Code 13 condition has not been serviced, an intermittent short to ground exists in air bag deployment wiring. Intermittent short to ground must be located and serviced before servicing a Code 51 condition.
