Power Seat Switch Circuit Failure
This code indicates a problem with the power seat switch circuit.
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 power seat switch isn't sending the right signal to make the seat move. This could be due to a broken switch, bad wiring, or a blown fuse.
What the computer is actually seeing
The body control module (BCM) doesn't detect the expected voltage changes from the power seat switch when operated. Normally, pressing the switch sends around 12V to the seat motor; if it sees no change, it throws this code.
What a healthy reading looks like
When the switch is pressed, the voltage should drop from 12V to near 0V as the circuit closes and activates the motor.
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.
- 1Check the fuse for the power seat circuit. If blown, replace and retest.
- 2Inspect the wiring for any visible damage or loose connections between the switch and the motor.
- 3Test the power seat switch with a multimeter. When pressed, it should show continuity.
- 4Check the voltage at the power seat motor. If no voltage is present while operating the switch, further investigate the wiring and connectors.
- 5If everything checks out but the seat still doesn't move, consider replacing the power seat motor.
Common causes
- Faulty power seat switch
- Frayed or damaged wiring
- Blown fuse
- Faulty body control module (BCM)
- Bad seat motor
