B0580Driver Seat Memory Module Malfunction
- Generic OBD-II code · Body
- How the car detects it
- B0580 is absent from publicly available J2012 lists and lacks a public manufacturer definition. The title describes an internal fault of the driver seat memory module. GM's 2011 Saab 9-5 shows what such a module checks in itself: B3920 42 when its calibration was never programmed, B3920 00 when the current leaving a motor rail differs from the returning current, plus voltage faults on the rail; the module then refuses those motors, and a stored code disappears once 40 ignition cycles pass without the fault. In the Saab 9-3, B3920 01 (output above 12 V while inactive) cancels all memory functions, while a stuck memory button (B2755 01) is merely ignored. Chrysler's US4682088A keeps stored positions in non-volatile memory.
