Lamp Fault Codes (LFCs)
The lamp fault code (LFC) indicates the specific fault associated with diagnostic trouble code (DTC) B2432.
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 restraints control module (RCM) whether the safety belts are buckled or unbuckled.
The RCM checks the driver safety belt buckle switch circuits for faults. If the RCM detects an open circuit, it will store DTC B2432 in memory, flash LFC 5-1 on the air bag indicator and the secondary air bag warning chime will be activated.
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.
