Test W: Right Side Air Bag Circuit Resistance Low (DTC B1999): 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) monitors resistance of right side air bag module circuits at connector C2041B, terminals No. 5 (White/Yellow wire) and No. 6 (Brown/Yellow wire). If RCM detects resistance less than 1.4 ohms, it will store Diagnostic Trouble Code (DTC) B1999 in memory and flash Code 36 on AIR BAG warning light.
