Normal Operation
The Restraints Control Module (RCM) monitors the driver seat side air bag circuits at RCM C310b pins 2 and 3 for a short to battery or ignition. If battery or ignition voltage is detected, the RCM will store Diagnostic Trouble Code (DTC) B1992 and Flash Lamp Fault Code (LFC) 36.

Possible Causes
A driver seat side air bag circuit short to battery or ignition can be caused by:
^ battery or ignition voltage on circuit 30S-JA38 (RD/BK).
^ battery or ignition voltage on circuit 31S-JA38 (BK/RD).
^ battery or ignition voltage short in the driver seat side air bag module.
^ RCM is faulted.
