B0570Passenger Power Seat Forward/Back Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0570 is not found in any J2012 list open to the public, nor in published manufacturer material. Its title covers the fore/aft motor of the front passenger seat. The Saab 9-3 passenger seat module shows how such a circuit is policed: B1770 04 for an open output, 0B above 40 A, and 61 when a relay is stuck to ground, detected right after a soft start because the output exceeds 6 V. In the last case the seat no longer moves in the selected direction but still travels the other way; in all cases memory functions stop. As TI's note on memory seats explains, position is commonly tracked by Hall sensors on the motor whose revolutions are converted into seat travel. Driver side: B0560.
