Power Seat Switch Circuit Failure
There’s a problem with the power seat switch wiring or the switch itself.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The seat won't move because the wires or the switch that control it are broken or shorted out.
What the computer is actually seeing
The seat control module detects an open circuit or excessive resistance in the power seat switch circuit when the switch is activated.
What a healthy reading looks like
When the switch is pressed, the voltage should change from 0V (off) to around 12V (on), depending on the direction.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Inspect the power seat switch for physical damage or wear.
- 2Check the wiring and connectors for any signs of fraying, corrosion, or disconnection.
- 3Using a multimeter, measure voltage at the switch connector while pressing the seat switch; expect 12V when pressed.
- 4Check the ground connection for the seat control module; it should have continuity to ground.
Common causes
- Faulty power seat switch
- Damaged wiring or connectors
- Poor ground connection for the seat control module
Typical repair cost
$100-$300

Frequently asked questions
Can I still drive the vehicle with this code?

Is this code likely to come back after I fix it?
If properly repaired, it should not come back unless there's a new issue with the wiring or switch.
Can this problem affect other electrical systems in the car?
Not directly, but if the wiring is compromised, it can cause intermittent electrical issues.
