Brake Control Module Fault
The brake control module detected a fault due to internal issues or communication errors.
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)
Inside the brake control module, a fault has been detected. This could be due to a bad connection, internal failure, or communication loss with other modules.
What the computer is actually seeing
The brake control module sees inconsistent or malformed data from the sensors or internal checks, triggering a fault state.
What a healthy reading looks like
Look for the module to respond to commands within 10 ms and voltages should be between 9V and 14V when the vehicle is on.
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 brake control module wiring harness for any visible damage or corrosion.
- 22. Ensure all connectors are securely attached and free of dirt or moisture.
- 33. Use a multimeter to check the power supply to the module—voltage should be between 9V and 14V.
- 44. Check for communication with other modules. Use a scan tool to verify data exchange; look for any other codes present.
- 55. If wiring and connections are good, consider replacing the brake control module.
Common causes
- Corroded connectors at the brake control module
- Faulty brake control module
- Wiring issues leading to poor communication

Frequently asked questions
Is it safe to drive with this code?
Moderate severity suggests it's best to fix it soon as it may impact braking performance.
Will this code come back after clearing it?
Yes, if the underlying issue isn't resolved, the code will likely return.
Why does this code appear with other codes?
Complex systems like brakes often have interdependencies; faults in one can reflect issues in others.
