Description:

This error code is triggered when the park brake system maintains a pressure above 50 kPa (0.5 bar) (7 psi), which can cause the park brake to engage only partially.

Reaction:

The control unit commands the equipment to enter Park mode, which is recoverable.

Recommendations:

• Inspect Park Brake Pressure:
  • Check the park brake pressure to ensure it is below the specified threshold when park is commanded.
  • Adjust the pressure if necessary to ensure complete engagement or disengagement of the park brake.
• Evaluate Hydraulic System:
  • Inspect the hydraulic system for any issues that may cause elevated pressure.
  • Repair or replace any faulty components or leaks.
• Test Pressure Sensors:
  • Verify that the pressure sensors are functioning correctly and providing accurate readings.
  • Replace faulty sensors if needed.

Note:

Ensuring proper pressure levels in the park brake system is crucial for full engagement and safe operation.
