This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that the sensor that tells it where the brake pedal is pushed too hard or is not working right.
This code indicates that the voltage signal from the brake pedal position sensor is higher than expected, suggesting a malfunction.
The Brake Pedal Position Sensor 'A' is responsible for sending a voltage signal to the vehicle's ECU to indicate the position of the brake pedal. A voltage out of range high code means that the signal is above the expected range, which could be due to a sensor fault, wiring issue, or ECU problem.
• Brake warning light on the dashboard
• Unresponsive brake lights
• Inconsistent braking performance
• Faulty brake pedal position sensor
• Wiring issues such as shorts or open circuits
• Malfunctioning ECU

• Check for any visible damage to the brake pedal position sensor and its wiring.
• Use a multimeter to measure the voltage output from the sensor.
• Inspect the ECU for any signs of damage or faults.
• Replace the brake pedal position sensor if faulty.
• Repair or replace damaged wiring or connectors.

Sensor Issue
• Do not ignore the brake warning light on the dashboard.
• Have the vehicle inspected by a professional if unsure.
Check with the vehicle manufacturer for warranty coverage on sensors and related components.
This code has been commonly reported in vehicles with high mileage or those exposed to harsh conditions.
High – Brake system issues can affect vehicle safety and should be addressed promptly.
Driving with a malfunctioning brake system can be dangerous and is not recommended. Always ensure your vehicle's brakes are in good working condition.
• Vehicle must be stationary.
• Ensure the ignition is in the 'On' position without starting the engine.
The brake pedal position sensor is typically located near the brake pedal assembly inside the cabin.
Q: Can I drive with a C10BC code?
A: It's not recommended to drive with this code as it may affect the braking system's performance.
Q: How do I reset the C10BC code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, it should not return.
