Normal Operation
The Restraints Control Module (RCM) monitors the resistance to ground at RCM C2041b pins 5 and 6. If the resistance is less than 1000 ohms at either pin, the RCM will interpret that as a ground short, store Diagnostic Trouble Code (DTC) B1997 and flash Lamp Fault Code (LFC) 37.

Possible Causes
A passenger seat side air bag circuit short to ground can be caused by:
^ grounded wiring on circuit 1259 (WH/YE).
^ damaged wiring on circuit 1260 (BN/YE).
^ ground short in the passenger seat side air bag module.
^ a faulted RCM.
