Power Seat Switch Circuit Failure
The power seat switch has a malfunction or is not communicating.
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 controls the movement of the seat. If there's an issue here, the seat won’t move as it should, which might be due to a faulty switch or a wiring issue.
What the computer is actually seeing
The vehicle computer detects an unexpected voltage level or open circuit in the power seat switch circuit when the switch is activated.
What a healthy reading looks like
Expected voltage should be around 12V when the switch is activated. If you see 0V or fluctuating voltages, there's a problem.
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.
- 11. Check power and ground at the power seat switch connector. You should see around 12V when the switch is activated. If not, check for power going to the connector.
- 22. Inspect the wiring and connectors for damage or corrosion. Ensure that there are no frayed wires or loose connections.
- 33. Test the power seat switch itself using a multimeter. In a functional switch, you should get continuity when the switch is pressed. No continuity indicates a bad switch.
- 44. If the switch is good, check the connections at the seat motor. Test the motor for continuity as well. If the motor does not show continuity, it may be faulty.
Common causes
- Failed power seat switch
- Wiring damage or corrosion
- Connector issues at the switch or motor
- Faulty seat positioning motor
