B1B53 DODGE 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.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
