Code B1C4A Description
The B1C4A diagnostic trouble code (DTC) indicates that there is a short circuit in the 1st row passenger retractor tensioner circuit. The retractor tensioner is a crucial component of the vehicle's seatbelt system, responsible for tightening the seatbelt in the event of a collision to restrain the occupant properly. When this circuit is shorted together, it can compromise the effectiveness of the seatbelt system, potentially leading to serious safety concerns for the passenger in the event of an accident.
Common Causes of B1C4A
- Damaged wiring harness.
- Faulty retractor tensioner.
- Loose or corroded electrical connections.
- Malfunctioning control module.
- Impact or collision that damaged the seatbelt system.
Symptoms of B1C4A
- Airbag warning light illuminated on the dashboard.
- Seatbelt not retracting properly.
- Inability to fasten the seatbelt securely.
- Audible warning chime when the seatbelt is not buckled.
- Loss of tension in the seatbelt during sudden stops or impacts.
How to Fix B1C4A
- Begin by conducting a thorough visual inspection of the seatbelt system, looking for any visible signs of damage or wear.
- Use a multimeter to test the continuity of the wiring harness and connections to identify any short circuits.
- Inspect the retractor tensioner for proper functionality and replace it if necessary.
- Reset the SRS system using a diagnostic tool to clear the DTC and ensure that the issue has been resolved.
- Conduct a test drive to verify that the seatbelt system is functioning correctly and that the airbag warning light has been extinguished.
Cost to Fix B1C4A

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.
