As part of the SRS, the safety belt buckles are equipped with Hall-effect switches. The safety belt switches indicate to the restraints control module (RCM) whether the safety belts are connected or disconnected. Refer to AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS) .
The RCM checks the driver safety belt buckle switch circuits for faults. If the RCM detects a current out of range fault, it will store DTC B2435 in memory, flash LFC 7-5 on the air bag indicator and the secondary air bag warning chime will be activated.
