B0570 code meaning
Passenger Power Seat Forward/Back Circuit
What B0570 means
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.

- Note B0570 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.
