Test U: Right Side Air Bag Circuit Short To Ground (DTC B1997): Description
WARNING: This page is about a different car, the 2002 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) checks right side air bag module circuits for short to ground by monitoring resistance to ground at RCM harness connector C2041B, terminals No. 5 (White/Yellow wire) and No. 6 (Brown/Yellow wire). If RCM detects resistance less than 10 k/ohms at either terminal, it will store Diagnostic Trouble Code (DTC) B1997 in memory and flash Code 37 on AIR BAG warning light.
