Power Seat Control Module Fault
Issue with power seat control module communication or performance.
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 control module isn’t sending or receiving signals properly, which can cause the seat to stop moving or adjust erratically.
What the computer is actually seeing
The power seat control module detects an abnormal condition within its operation or communication with other modules, triggering a fault code if parameters are out of range.
What a healthy reading looks like
The power supply voltage should be between 9V to 16V at the power seat module. Signal pulses from the switch should be at least 2.5V when active, expected to change according to the switch inputs.
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 the power and ground at the power seat control module. The voltage should be within 9V to 16V. If not, check the battery and fuse.
- 22. Inspect wiring and connectors for any visible damage or corrosion. Repair as needed.
- 33. With the key in the ON position, use a multimeter to test the input voltage at the seat switch. Look for at least 2.5V when the switch is activated.
- 44. If all wiring and switch signals are good, consider replacing the power seat control module.
Common causes
- Faulty power seat control module
- Wiring issues (shorts or open circuits)
- Poor connections or corroded connectors
- Faulty seat switch or controls
Typical repair cost
