What B0001 means
The supplemental restraint system (SRS) module has detected a fault in the deployment control circuit for the first stage of the driver frontal airbag.
How the engine computer detects it
The SRS warning lamp illuminates and airbag deployment may be impaired in a crash event.
Written from public technical sources and not yet checked by a mechanic. How we write these pages
Symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
Common causes
- Clock spring (spiral cable) damaged in steering column Most likely
- Loose or corroded airbag connector under steering wheel Possible
- SRS control module internal fault Less likely
How to diagnose B0001
- Read every stored code with an OBD-II scanner. If misfire or fuel trim codes are there too, fix those first: they often cause this one.
- Inspect the parts involved: driver airbag module, srs control module, srs wiring, clock spring.
- Work through the causes above from most to least likely, cheapest checks first.
- Clear the code and drive a full drive cycle to confirm the repair held.

Questions drivers ask
Can I drive with code B0001?
The car drives normally, but with the airbag light on some airbags or seatbelt pretensioners may not work in a crash. Get the system checked soon, and leave airbag parts to a shop: they can deploy and injure you.
Often reported together
Codes that owners mention in the same NHTSA complaints as B0001. They can point to a shared cause, so it's worth checking them together.
