Description:

This error code is triggered when the park brake pressure drops below 1305 kPa (13 bar) (190 psi) while the park brake is commanded off. This indicates a potential issue with the park brake system not maintaining adequate pressure.

Reaction:

The control unit limits functionality to prevent potential damage.

Recommendations:

• Inspect Pressure Sensor:
  Check the park brake pressure sensor for proper operation. Replace if it is faulty.
• Check Park Brake System:
  Inspect the park brake system for any components that might be causing inadequate pressure, such as valves or actuators. Repair or replace as necessary.
• Verify Calibration:
  Ensure the park brake system is properly calibrated to maintain the correct pressure levels.
• Check for Leaks:
  Inspect the hydraulic lines and components for any leaks that might be causing a drop in pressure. Repair as necessary.
• Consult Technical Support:
  If the issue persists, consult technical support or the manufacturer for further assistance.

Note:

Maintaining proper pressure in the park brake system is crucial for safe vehicle operation. Regular inspections and maintenance can help prevent related issues.
