Brake Switch Circuit Failure
This code indicates a problem with the brake switch 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)
The brake switch isn't functioning properly, which means the system can't tell if you're pressing the brake pedal or not, affecting functions like ABS or traction control.
What the computer is actually seeing
The powertrain control module (PCM) monitors voltage from the brake switch. With the brake released, the switch should show around 5V. When pressed, it should drop to close to 0V, indicating activation.
What a healthy reading looks like
Brake switch voltage should be 5V when released and close to 0V when pressed.
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 fluid level; it should be within the recommended range.
- 22. Inspect the brake switch and its wiring for damage or disconnections. Ensure connectors are tight and free of corrosion.
- 33. Measure the voltage at the brake switch: it should show approximately 5V when the pedal is not pressed. Press the pedal and check if it drops to near 0V. If it does not, the switch is likely faulty.
- 44. If the switch tests good, connect a scan tool and monitor the brake switch status while pressing the pedal. If the status does not change, repair the wiring to the PCM.
- 55. If wiring and switch are functional, check the PCM for faults or damage.
Common causes
- Faulty brake switch
- Wiring issues (frayed or shorted)
- Bad connectors at the brake switch or PCM
Typical repair cost
