B0580 Driver Seat Memory Module Malfunction

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.

Likely causes

Replacement module installed without calibration or setup
Internal electronic fault of the memory module
Liquid under the seat reaching the module
Low battery voltage or poor module ground

Symptoms

  • Memory buttons do not recall seat or mirror positions
  • Power seat partly or completely inoperative
  • Stored positions lost after power interruption

Repair estimate

DifficultyHardWorkshop job
Parts and labour€150–800
Time0.5–3 h

Typical range across vehicles; the real cost depends on what the testing finds.
