B0327 code meaning
Passenger Seat Position Memory
What B0327 means
No known public list or manufacturer document defines B0327. The title is vague: it suggests a fault in storing or restoring positions of a power passenger seat. For that a module needs working position feedback; in Saab's 9-3 passenger seat module a lost slide sensor signal (B2375) switches off all memory functions and erases the end-stop calibration. US4264849A shows stored positions recalled by push buttons for any vehicle seat, and US6320341B1 restores several cushion and backrest positions from pulse counts. Without a manufacturer definition the exact trigger is unknown; it likely corresponds to lost stored data or failed recall.

What each part of B0327 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). |
| 27 | The exact fault in that area. |
What to do next
- Note B0327 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.
