B0322 code meaning
Driver Seat Tilt Position Sensor
What B0322 means
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.

What to do next
- Note B0322 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
