Normal Operation
The restraints control module (RCM) checks the passenger safety belt buckle switch circuits for faults. If the RCM detects a short to voltage fault, it will store diagnostic trouble code (DTC) B2437 in memory and send a message to the instrument cluster module to illuminate the air bag warning indicator.

Possible Causes
A passenger safety belt buckle switch short to voltage fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty passenger safety belt buckle switch.
- RCM is faulted.
