B00B5Driver Seat Track Position Restraints Sensor
- Generic OBD-II code · Body
- How the car detects it
- B00B5 reports a fault of the driver seat track position sensor, which tells the airbag module whether the seat is pushed far forward toward the steering wheel. FCA uses it with exactly this meaning: GPOP tech tips for the Dodge Dart (PF), Jeep Cherokee (KL) and Chrysler 200 (UF) name B00B5-13, an open circuit, among codes to clear with engineering before replacing the restraint controller, and a 2024 tip for the Pacifica and Voyager (RU) asks for wiring, plug and low voltage checks first. Allegro describes the usual hardware, a two-wire Hall switch that the steel track shields from a magnet as it passes, giving zones. Honda lowers driver airbag force in the forward zone. Saab 9-3/9-5 file this sensor as B0084 and then disable the second airbag stage. The airbag lamp lights.
