Normal Operation

WARNING: Do not disconnect the wire connector at the side air bag module. This is a permanent connection. Doing so may result in air bag accidental deployment, which may result in personal injury.

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 side air bag circuit short to battery or ignition can be caused by:
- battery or ignition voltage on circuit 30S-JA37 (RD/GN).
- battery or ignition voltage on circuit 31S-JA37 (BK/GN).
- a faulted RCM.
