Brake Continuity Fault
The brake system has detected a continuity issue in the 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)
Your brake control module isn’t receiving the proper signals from the brake switch, which could be due to a broken wire or a faulty switch.
What the computer is actually seeing
The brake control module expects to see a closed circuit when the brake pedal is pressed, usually around 0.5 to 2 volts indicating the switch is engaged. If it reads open or no voltage (above 2 volts), it triggers a fault code.
What a healthy reading looks like
The brake switch should show a voltage drop to around 0.5 volts when the brake pedal is pressed, and return to around 12 volts when released.
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 the brake switch wiring and connector for damage, corrosion, or loose connections. Decision: If damaged, repair/replace. If okay, proceed to step 2.
- 22. Check the voltage at the brake switch connector with the pedal depressed. Expected: 0.5 volts. Decision: If correct, replace the brake control module. If wrong, proceed to step 3.
- 33. Test the brake switch by removing it and checking continuity with a multimeter. Decision: If no continuity when pressed, replace the switch. If there is continuity, check wiring integrity back to the module.
Common causes
- Damaged wiring harness
- Faulty brake pedal switch
- Corroded connector
- Faulty brake control module

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive if you cannot confirm proper brake function, as this could affect braking effectiveness.
Will this code come back after fixing?
If properly repaired, the code should clear and not return unless there's another underlying issue.
Why do I see this code paired with codes about the ABS?
The brake system is interconnected, so issues in the brake circuit can also affect ABS operation.
