B00F0Driver Inflatable Seat Belt Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- 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.
