B1B53 CHRYSLER Description

When powered, the Occupant Restraint Controller (ORC) sends a test current across the Driver Seat Belt Buckle Switch circuits every 100 ms to verify the integrity of the switch and wiring. The DTC will set if the circuits are shorted together for 2.5 seconds and the code will transitions from active to stored when the current returns to normal range for five seconds. The front seat belt switches cannot be adjusted or repaired and, if ineffective or damaged, the entire front seat belt buckle-half unit must be replaced. The airbag warning lamp will display in the instrument cluster for this fault. The ORC monitors the status of the seat belt switch circuits at power up and every 100 ms thereafter while the ignition is in on.
