Normal Operation
The restraints control module (RCM) checks the passenger safety belt buckle switch circuits for faults. If the RCM detects a current out of range fault, it will store diagnostic trouble code (DTC) B2439 in memory and flash lamp fault code (LFC) 52 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger safety belt buckle switch current out of range fault can be caused by:
- wiring, terminals, or connectors.
- a faulty passenger safety belt buckle switch.
- a faulted RCM.
