Code B1C2B Description
The B1C2B diagnostic trouble code (DTC) relates to the Right Side Seat Thorax Squib 1 being detected as low. In simpler terms, this code indicates an issue with the right side seat airbag system in the vehicle. The seat thorax squib refers to the component responsible for deploying the side airbag in case of a collision or impact. When this squib is detected as low, it means that there is likely an electrical or mechanical problem with the airbag system on the right side of the vehicle.
Common Causes of B1C2B
- Faulty seat thorax squib
- Loose wiring or connections in the airbag system
- Corrosion or damage to the airbag sensor
- Electrical issues such as a blown fuse or relay in the airbag circuit
- Impact or collision that damaged the airbag system components
Symptoms of B1C2B
- Airbag warning light illuminated on the dashboard
- Inability to turn off the airbag warning light
- Malfunctioning or erratic behavior of the airbag system
- Vehicle failing airbag system tests during inspection
- Error codes related to the airbag system appearing on the diagnostics tool
How to Fix B1C2B
- Begin by disconnecting the vehicle's battery to prevent any accidental deployments of the airbag system.
- Locate the right side seat thorax squib and inspect it for any visible damage or loose connections.
- Check the wiring harness and connections for any signs of wear, corrosion, or damage.
- Test the electrical components in the airbag system, such as fuses, relays, and sensors, to identify any faulty parts.
- Replace the defective seat thorax squib or any other damaged components in the airbag system, ensuring proper installation and connection.
Cost to Fix B1C2B

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.
Frequently Asked Questions about B1C2B Code
1. What does the OBDII code B1C2B mean?
The code B1C2B indicates a low voltage or resistance issue in the right side seat thorax airbag circuit, specifically in squib 1.
2. What are the common symptoms of the B1C2B code?
The most common symptoms include an illuminated airbag warning light and the potential deactivation of the airbag system on the passenger side.
3. What causes the B1C2B code to appear?
This code can be caused by faulty wiring or connectors, a damaged right side seat thorax airbag, a defective clock spring, or a malfunctioning airbag control module.
4. Can I still drive my car with the B1C2B code?
While the car may still drive normally, the airbag system may not deploy in an accident, which poses a safety risk.
5. How can I diagnose the B1C2B code?
