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

The restraints control module (RCM) checks the driver safety belt buckle switch circuits for faults. If the RCM detects a current out of range fault, it will store diagnostic trouble code (DTC) B2435 in memory and flash lamp fault code (LFC) 7-5 on the air bag indicator.

Possible Causes
A driver safety belt buckle switch current out of range fault can be caused by:
- a faulty driver safety belt buckle.
- a faulted RCM.
