Normal Operation
The Restraints Control Module (RCM) monitors the passenger side air bag circuits at RCM C1 pins 5 and 6 for a short to battery or ignition. If battery or ignition voltage is detected, the RCM will store Diagnostic Trouble Code (DTC) B1996 and flash Lamp Fault Code (LFC) 37.

Possible Causes
A passenger side air bag circuit short to battery or ignition can be caused by:
^ battery or ignition voltage on circuit 1259 (WH/YE).
^ battery or ignition voltage on circuit 1260 (BN/YE).
^ battery or ignition voltage short in the passenger side air bag module.
^ an RCM internal concern.
