Normal Operation
The restraints control module (RCM) checks the driver safety belt buckle switch circuits for faults. If the RCM detects a short to ground fault, it will store diagnostic trouble code (DTC) B2434 in memory and flash lamp fault code (LFC) 53 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver safety belt buckle switch circuit fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty driver safety belt buckle switch.
- a faulted RCM.
