Test H: Restraint System-Air Bag Status (DTC B2293): Description
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) checks all front air bag circuits for faults. If RCM detects low resistance, open circuit, short to battery or short to ground, it will store DTC B2293 in memory and flash Code 19 or 21 on AIR BAG warning light.
