Normal Operation
As part of the SRS, the safety belt buckles are equipped with Hall-effect switches. The safety belt buckle switch indicates to the RCM whether the safety belt is buckled or unbuckled.

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) 7-1 on the air bag indicator.

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