Test Q: Left Side Air Bag Circuit Short To Battery Or Ignition (DTC B1992): Description
WARNING: This page is about a different car, the 2002 Lincoln Blackwood. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) checks left side air bag module circuits for short to battery by monitoring connector C2041B, terminals No. 2 (White/Light Blue wire) and No. 3 (Brown/Light Blue wire). If RCM detects a short to battery, it will store Diagnostic Trouble Code (DTC) B1992 in memory and flash Code 36 on AIR BAG warning light.
