Description:

Error code BRC 523837.00 indicates an issue where the rear brake pressure remains high even though the right rear brake pedal command is off. This discrepancy suggests a potential malfunction within the hydraulic braking system or control unit, possibly due to a stuck valve, improper system calibration, or a sensor fault.

Reaction:

The control unit has detected this conflict and has degraded the function of the braking system to prevent potential over-braking or unintended braking actions, which could lead to safety hazards.

Recommendations:

• Inspect Brake Valves and Actuators: Check for any stuck valves or malfunctioning actuators that could be causing high pressure in the rear brakes despite the pedal command being off. Replace or repair as necessary.
• Calibrate Brake System: Ensure that the brake system calibration is up-to-date and accurately reflects the actual mechanical setup. Re-calibrate if discrepancies are found.
• Test Brake Pressure Sensors: Evaluate the functionality and accuracy of brake pressure sensors. Faulty sensors could incorrectly report high pressure.
• Review Control Unit Settings: Examine the settings and programming of the brake control unit to ensure they are correct and that there is no programming error causing the issue.
• Perform System Diagnostics: Run a full diagnostic check on the braking system to identify any hidden faults or anomalies that might contribute to the issue.

Note:

Regular maintenance and systematic checks of the braking system’s hydraulic components, sensors, and control logic are crucial for ensuring reliable operation and preventing issues like high brake pressure when not commanded. Addressing such conflicts promptly enhances vehicle safety and performance.
