B0580 code meaning
Driver Seat Memory Module Malfunction
What B0580 means
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.
B0580 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B0580
- Memory buttons do not recall seat or mirror positions
- Power seat partly or completely inoperative
- Stored positions lost after power interruption
Common causes of B0580
- PossibleReplacement module installed without calibration or setup
- PossibleInternal electronic fault of the memory module
- PossibleLiquid under the seat reaching the module
- Less likelyLow battery voltage or poor module ground
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0580 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 80 | The exact fault in that area. |
What to do next
- Note B0580 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.
Questions about B0580
What does B0580 mean?
B0580 means "Driver Seat Memory Module Malfunction". B0580 is absent from publicly available J2012 lists and lacks a public manufacturer definition. It is a generic code, so it means the same on every make.
Is it safe to drive with B0580?
B0580 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B0580 fail an emissions test?
B0580 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B0580 to fix?
Difficulty: hard. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will B0580 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
