This is the range for the most common fix, airbag clockspring replacement. Which repair your car needs depends on a proper diagnosis.
The airbag computer sees a problem in the driver airbag circuit, such as an open wire or a short. On many cars the clockspring in the steering column is the cause, since it carries power between the car and the wheel. It can vary by make, so check the scan tool or manual.
- Safe to drive?
- No, get it looked at first
- Most common cause
- Worn clockspring
The airbag system may be turned off, so the airbags may not deploy in a crash. Get it checked soon and avoid putting children in the front seat.

What you may notice

- Light comes and goes when turning
Common causes, most likely first
- Worn clockspring

- Damaged wire
- Faulty airbag module
- Bad driver airbag (less common)
Check this first
Note whether the horn and wheel buttons also fail, which strongly points to the clockspring. Do not poke at the airbag connector yourself.

B0001 questions
Why does the horn fail too?
The clockspring carries power for both the horn and the airbag. When it wears out, the horn and wheel buttons may stop at the same time the light comes on, which makes it a strong clue.
Is airbag work dangerous to DIY?
Yes. Disconnect the battery and follow the manual's wait time before touching anything, or use a shop. Working on an airbag circuit without proper steps can set off the bag by accident.
Does the airbag itself need replacing?
Usually not. The clockspring or a connector is far more likely than the airbag itself, and it costs much less. A shop should check the circuit before anyone suggests a new bag.
