B00F0 Driver Inflatable Seat Belt Deployment Control

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Airbag module variant expects a driver inflatable belt that is not fitted
Plug of the belt gas generator at the lower anchor or seat loose or corroded
Lead to the inflator chafed by seat adjustment
Igniter of the belt inflator faulty

Symptoms

  • Airbag warning lamp on
  • Driver belt would not inflate in a crash
  • Safety note: the belt contains a pyrotechnic gas generator; work only de-energised (battery off, wait time) and at a specialist workshop
