Description:

This error code is triggered when the park brake pressure drops below 750 kPa (7.5 bar) (108 psi) in come home mode with the engine off or while towing the vehicle. The code is generated to alert the operator when park brake pressure falls to a level where the park brake could engage.

Reaction:

The control unit limits the functionality of the equipment to prevent potential damage.

Recommendations:

• Inspect Brake Pressure:
  • Check the park brake pressure to ensure it is above the specified threshold, especially in come home mode.
  • Inspect for any leaks or blockages in the brake lines.
• Verify Operational Procedures:
  • Ensure that the correct operational procedures are being followed, especially when towing or in come home mode.
• Test Pressure Sensor:
  • Verify that the pressure sensor for the park brake is operating correctly.
  • Replace the sensor if it is found to be defective.

Note:

This code can be operator-induced. Regularly checking the park brake pressure and following correct operational procedures are essential to prevent unintended brake engagement and ensure safe operation.
