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

The restraints control module (RCM) checks the driver safety belt buckle switch circuits for faults. If the RCM detects an open circuit, it will store diagnostic trouble code (DTC) B2432 in memory and flash lamp fault code (LFC 5-1) on the air bag indicator.

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