Normal Operation
The Restraints Control Module (RCM) Monitors The Resistance To Ground At RCM C1 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 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 side air bag module.
^ an RCM internal concern.
