B0561Driver Power Seat Up/Down Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0561 has no entry in the accessible J2012 lists and no public manufacturer definition. The title refers to the motor that raises and lowers the driver seat; Chrysler's US4682088A splits this into front and rear cushion motors with about 1.5 in of travel. In the Saab 9-3 the height motor circuit is B1765 in the driver seat module: 04 for an open output, 0B for more than 40 A; the output is shut off and retried once per ignition cycle. GM's 2011 Saab 9-5 instead tests a shared 2.5 V bias point before any seat motor runs and sets B3920 if it stays above 2.78 V or under 1.47 V for a tenth of a second, blocking every motor on that power rail. A failed height axis therefore often stops other axes too.
