C0200: ABS/TCS Brake Switch Circuit Malfunction
Can you still drive? Use caution. If brake lights are not working, other drivers cannot see you braking, which is very dangerous. Check brake lights first and repair immediately if they are out.
What Does C0200 Mean?
Code C0200 indicates that the ABS and traction control system has detected a problem with the brake switch circuit. The brake switch tells the ABS module when the driver is pressing the brake pedal. Without this input, the ABS and traction control systems cannot determine driver intent and may be disabled.

Frequently Asked Questions
Can a missing pedal bumper cause C0200?
Yes, the small rubber bumper on the brake pedal arm positions the switch correctly. When it falls off, the switch can become misadjusted, triggering C0200 and causing brake light issues.
Why does C0200 affect cruise control?
The cruise control system uses the brake switch signal to disengage when you tap the brakes. If the switch is faulty, cruise control may not work or may not cancel properly.
