Code B1B05 Description
The B1B05 diagnostic trouble code (DTC) indicates an issue with the Driver Airbag Squib 2 Circuit being too high. The Driver Airbag Squib is a component of the vehicle's airbag system that is responsible for deploying the driver's airbag in the event of a collision. The circuit high fault suggests that there is an abnormally high voltage in the circuit, which can prevent the airbag from deploying properly in an accident.
Common Causes of B1B05
- Faulty driver airbag squib.
- Wiring or connection issues in the airbag circuit.
- Corrosion or damage to the airbag system components.
- Issues with the airbag control module.
- Electrical problems within the vehicle's system.
Symptoms of B1B05
- Airbag warning light illuminated on the dashboard.
- Inability to deploy the driver's airbag in a collision.
- Faulty horn operation.
- Issues with the vehicle's cruise control system.
- Loss of communication with the airbag control module.
How to Fix B1B05
- Begin by diagnosing the specific cause of the high circuit voltage using a diagnostic scanner.
- Inspect the wiring and connections in the airbag circuit for any damage or corrosion.
- Test the driver airbag squib for proper functionality and replace if necessary.
- Clear the DTC from the vehicle's system using the diagnostic scanner.
- Perform a thorough test of the airbag system to ensure proper operation.
Cost to Fix B1B05

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.
