Normal Operation
The restraints control module (RCM) checks the passenger safety belt buckle switch circuits for faults. If the RCM detects an open circuit or short to voltage fault, it will store diagnostic trouble code (DTC) B2692 in memory and flash lamp fault code (LFC) 54 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger safety belt buckle switch open circuit or short to voltage fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty passenger safety belt buckle switch.
- RCM is faulted.
