Seat Control Module
Controls a powered seat's adjustment, and on many vehicles stores memory positions tied to a key or driver profile.
It is easy to dismiss as a comfort device, and on many vehicles that is a mistake — because the same module frequently carries the occupant classification system. A front passenger seat contains sensing whose job is to decide whether the airbag should deploy and how hard: an empty seat, a child seat and an adult each call for different behaviour. Where that reports through the seat module, losing the module means the restraint system has lost the information behind that decision, and the correct response is to disable the passenger airbag and light the airbag lamp. So the question that sets the severity is whether the airbag warning light is on.
Physically the causes are mundane and consistent: the harness runs under the seat, flexes every time the seat slides, and sits exactly where feet, luggage and spilt drinks arrive. Seats also come out for a great many unrelated jobs — carpet, trim, floor repairs, retrofits — and a connector left unmated or a loom pinched under a rail during refitting is an ordinary cause. Where memory profiles are stored, a replacement usually needs coding to the vehicle and loses every stored position.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
