Possible Causes

WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

A driver-side air bag status fault could be caused by faulty wiring, terminals or connectors, faulty clockspring, faulty driver-side air bag module or faulty RCM. A passenger-side air bag status fault could be caused by faulty wiring, terminals or connectors, faulty passenger-side air bag module or faulty RCM.
