B00F1Passenger Inflatable Seat Belt Deployment Control
- Generic OBD-II code · Body
- How the car detects it
- B00F1 is the front passenger counterpart of B00F0, reserved for an inflatable belt at that seat. No manufacturer documents it, and no series vehicle is publicly known to have a passenger inflatable belt; Mercedes' S-Class manual offers the beltbag only for the outer rear belts. A passenger version would still face the same engineering choices as the patents show: Allied Chemical patented as early as 1972 a buckle that routes gas from a floor-mounted inflator through tongue and buckle into lap and shoulder belt, so the belt itself needs no wires, while Autoliv's 2002 design mounts separate inflators on the seat back. The airbag module would watch the igniter loop and set B00F1 for an open, a short or bad resistance.
