Normal Operation
The Restraints Control Module (RCM) monitors the resistance to ground at RCM C310b Pins 5 and 6. If the resistance is less than 10,000 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 30S-JA38 (RD/BK).
^ damaged wiring on circuit 31S-JA38 (BK/RD).
^ ground short in the passenger seat side air bag module.
^ RCM is faulted.
