About this code
Code B0001 indicates an electrical circuit fault in the driver steering wheel airbag. In most vehicles, a fractured clock spring ribbon wire inside the steering column is the cause. While the car drives normally, your life-saving airbag will NOT deploy in an accident. Fix it promptly.
