Code B1B05 Dodge Description
The B1B05 diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Driver Airbag Squib 2 Circuit being too high. The driver airbag squib is a component responsible for deploying the airbag in case of a collision or impact. When the circuit is detected to have a high resistance or voltage, it means that there is a problem with the electrical connection or the squib itself, which could prevent the airbag from deploying in an accident.
Common Causes of B1B05 Dodge
- Damaged wiring harnesses leading to high resistance in the circuit.
- Faulty driver airbag squib causing high voltage output.
- Poor electrical connections between components.
- Issues with the airbag control module not communicating properly with the squib.
- Manufacturing defects in the airbag system components.
Symptoms of B1B05 Dodge
- Illuminated airbag warning light on the dashboard.
- Non-deployment of the driver airbag in a crash.
- Intermittent or sporadic functioning of the driver airbag.
- Fault codes related to the airbag system stored in the vehicle's computer.
How to Fix B1B05 Dodge
- Start by conducting a thorough inspection of the wiring harnesses, connectors, and the driver airbag squib for any visible damage or corrosion.
- Test the resistance and voltage levels in the circuit using a multimeter to identify any abnormalities.
- Replace any damaged wiring harnesses, connectors, or the driver airbag squib if necessary.
- Clear the DTCs from the vehicle's computer using a diagnostic scan tool and perform a test to ensure the airbag system functions correctly.
- If the issue persists, further diagnostic testing may be required to pinpoint the exact cause of the problem.
Cost to Fix B1B05 Dodge

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.
