Normal Operation
The restraints control module (RCM) monitors 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 send a message to the instrument cluster module to illuminate the air bag warning 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.
