B00F0 code meaning
Driver Inflatable Seat Belt Deployment Control
What B00F0 means
B00F0 is the firing circuit for an inflatable belt at the driver's seat: a section of webbing that a gas source fills in a crash so the load spreads over a wider area of the chest. The production inflatable belts known from Ford and Mercedes-Benz sit only at rear outer seats; no carmaker documents B00F0. The idea for front seats is old and well described in patents, for example a Daimler design of 2010 with the gas generator at the lower anchor beside the B-pillar and folded webbing held by tear threads, and an Autoliv design with inflators mounted on the seat back. Joyson also lists a belt-attached restraint supplement among its airbag innovations. If the code is set, the airbag lamp comes on.

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00F0 means

| 0 | Generic code: it means the same on every make (SAE standard). |
| F0 | The exact fault in that area. |
What to do next
- Note B00F0 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
