Test T: Left-Side Air Bag Circuit Short To Ground (DTC B1993): Description
WARNING: This page is about a different car, the 2003 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.
