  • Inspect Hydraulic System:
    • Thoroughly check the hydraulic system for leaks, especially in system 1.
    • Repair or replace any leaking components.
  • Evaluate Hydraulic Pressure:
    • Ensure the hydraulic pump is operating correctly and providing adequate pressure.
    • Check fluid levels and refill if necessary.
  • Test Pressure Sensors:
    • Verify that the pressure sensors for both park and enable pressures are functioning correctly.
    • Replace any faulty sensors.


Identifying and fixing hydraulic leaks promptly is critical to maintain proper system pressure and ensure reliable operation. Regular inspections and maintenance can help prevent such issues.
