Lamp Fault Codes (LFCs)
The lamp fault code (LFC) indicates the specific fault associated with diagnostic trouble code (DTC) B2433:
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 a short to battery fault, it will store DTC B2433 in memory and flash LFC 7-9 on the air bag indicator.
Possible Causes
A driver safety belt buckle switch short to battery circuit fault can be caused by:
- wiring, terminals or connectors.
- a faulted RCM.
