B00B6Driver Seat Recline Position Restraints Sensor
- Generic OBD-II code · Body
- How the car detects it
- B00B6 concerns a sensor that tells the restraint system how far the backrest of the driver seat is reclined. No carmaker documents this code publicly, and the NHTSA bulletin index has no entry for it. Patents show why the angle matters: an ATI patent lets the controller suppress or depower the airbag from seat position, back angle and belt spool-out alone, without looking at the occupant, and a Bosch application derives the tilt from a three-axis accelerometer in the seat back, uses a 45 degree limit to decide which airbags fire and feeds the angle into occupant classification. Autoliv even calibrated its classification mat at several back angles. If B00B6 is stored the module loses that input; the airbag lamp stays on until the sensor or its circuit is repaired.
