This summary uses the existing diagnostic information shown in full below.
This means there's too much pressure in the brakes at the back wheels of the car. It's like squeezing a balloon too hard.
The vehicle's onboard computer has detected that the pressure in the rear brake circuit is higher than normal, which could affect braking performance.
The C10A6 code indicates that the pressure sensor in the rear axle brake circuit has detected a pressure reading that exceeds the manufacturer's specified limits. This could be due to a malfunctioning pressure sensor, a blocked brake line, or a fault in the brake system's control module.
• Increased stopping distance
• Brake warning light on
• Unusual brake pedal feel
• Faulty brake pressure sensor
• Blocked or kinked brake line
• Malfunctioning brake control module
OBD-II: On-Board Diagnostics, a standardized system for vehicle self-diagnosis and reporting.
Brake Pressure Sensor: A device that measures the pressure within the brake lines.
• Check for any brake fluid leaks or blockages in the brake lines.
• Test the brake pressure sensor for correct operation.
• Inspect the brake control module for faults.
• Replace faulty brake pressure sensor.
• Clear any blockages in the brake lines.
• Reprogram or replace the brake control module if necessary.
• OBD-II scanner
• Brake pressure gauge
• Multimeter

Brake System Issue
• Do not drive the vehicle until the issue is resolved.
• Consult with a professional mechanic for a thorough inspection.
Check with your vehicle manufacturer for specific warranty coverage related to brake system components.
This code has been associated with vehicles experiencing brake performance issues due to sensor malfunctions or hydraulic problems.
High – Brake issues can compromise vehicle safety and should be addressed immediately.
Driving with a malfunctioning brake system can be dangerous and may violate vehicle safety regulations.
• Vehicle in a safe, stationary position
• Brake system at normal operating temperature
The rear axle brake pressure sensor is typically located near the rear brake assembly or along the brake lines leading to the rear wheels.
Q: Can I drive with the C10A6 code?
A: It is not recommended to drive with this code active as it may affect braking performance.
Q: How do I reset the C10A6 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
