Test T: Left Side Air Bag Circuit Short To Ground (DTC B1993): Description
WARNING: This page is about a different car, the 2002 Mazda Tribute. 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 circuit for shorts to ground by monitoring voltage at RCM harness connector C2041B, terminals No. 2 (White/Light Blue wire) and No. 3 (Brown/Light Blue wire). If RCM detects resistance less than 10 k/ohms at either terminal, it will store Diagnostic Trouble Code (DTC) B1993 in memory and flash Code 36 on AIR BAG warning light.
