B0322Driver Seat Tilt Position Sensor
- Generic OBD-II code · Body
- How the car detects it
- B0322 lacks any public definition, either in J2012 lists or from a manufacturer. The title describes the sensor reporting the cushion tilt of the power driver seat, normally made by raising or lowering the front edge. Saab's 9-3 driver seat module calls it the tilt position sensor and stores B3923: 01 above 7 ± 0.2 V, 02 when shorted to ground, 04 for an open line and 29 when no pulses arrive while the engine runs. Memory recall then stops and the end-stop calibration of the tilt motor is lost. US4682088A measures front and rear cushion height with potentiometers, while US6320341B1 restores the front cushion portion by pulse counting. Fore-aft feedback is B0310.
