Test J: Restraint System-Impact Sensor Status (DTC B2296): 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 front and side impact sensor circuits for faults. If RCM detects low resistance, open circuit, short to battery or short to ground, it will store DTC B2296 in memory and flash Code 42, 43 or 44 on AIR BAG warning light.
