Normal Operation
The restraints control module (RCM) checks the passenger safety belt buckle switch circuits for faults. If the RCM detects a short to ground fault, it will store diagnostic trouble code (DTC) B2438 in memory and flash lamp fault code (LFC) 52 (or higher priority code if 1 exists) on the air bag indicator.

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