Motor Relay Circuits Malfunction
Issues with the motor relay circuits in the vehicle's stability control system.
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 stability control system uses motor relays to send power to various components. If there's a problem, it might affect how well the car keeps traction, especially on slippery roads.
What the computer is actually seeing
The vehicle is detecting an abnormal voltage or resistance level in the motor relay circuit, indicating a malfunction that could affect stability control.
What a healthy reading looks like
Motor relay voltage should be between 12-14 volts when activated. Resistance in the wiring should be below 5 ohms.
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. Inspect wiring and connectors for physical damage or corrosion. If any issues found, repair and retest.
- 22. Check the voltage at the motor relay. With the engine running, you should see 12-14 volts. If not, diagnose power supply.
- 33. Test the resistance of the relay circuit. Should be below 5 ohms, if above, inspect wiring for shorts or opens.
- 44. If the circuit checks out, swap the motor relay with a known good relay. If code returns, further diagnose the stability control module.
Common causes
- Faulty motor relay
- Damaged wiring or connectors
- Software glitch in the stability control module

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; you may experience reduced traction control, so avoid slippery conditions until repaired.
Will this code come back after a reset?
If the underlying issue isn't fixed, the code will likely return after a short while.
Why does it pair with other codes?
Issues in the motor relay circuit can trigger related codes, as they all interact with the stability control system.
