• Clogged Hydraulic Lines: Obstructions in the hydraulic lines or excessive pressure drop in the system can prevent the proper flow of fluid, resulting in failure of the auxiliary hydraulics.
  

• Check Hydraulic Fluid: Start by checking the hydraulic fluid level and condition. Ensure the fluid is clean and at the proper level. If the fluid is low or contaminated, replace or top it up with the recommended hydraulic fluid.
  
• Inspect the Hydraulic Control Valve: Inspect the hydraulic control valve for any issues. Ensure the valve is functioning correctly and able to switch to auxiliary hydraulic mode. If the valve is sticking or malfunctioning, it may need to be repaired or replaced.
  
• Examine the Electrical System: Check the electrical components, including fuses, relays, and wiring, for any faults. Use a multimeter to test the electrical components and ensure the system is sending the correct signals to the hydraulic control valve.
  
• Test the Hydraulic Pump: Measure the hydraulic pump’s output pressure with a pressure gauge. If the pressure is lower than the required level, the pump may be faulty and need to be repaired or replaced.
  
• Check Sensors: Inspect the sensors within the hydraulic system for any malfunctions. If any sensors are faulty, they may need to be recalibrated or replaced.
  
• Inspect Hydraulic Lines: Check the hydraulic lines for blockages, leaks, or restrictions. Ensure that the fluid can flow freely through the lines. If there are any blockages, clean the lines or replace the affected sections.
  

• Replace or Top Up Hydraulic Fluid: If the hydraulic fluid is low or contaminated, replace or top up with the correct type of hydraulic fluid. Ensure that the fluid is clean and meets the equipment's specifications.
  
• Repair or Replace the Hydraulic Control Valve: If the hydraulic control valve is malfunctioning, it should be repaired or replaced. This ensures that the fluid can be directed correctly to the auxiliary system.
  
• Repair Electrical System Issues: If there are issues with the electrical system, such as faulty fuses, relays, or wiring, these components should be repaired or replaced to ensure proper signal transmission to the hydraulic control system.
  
• Replace or Repair the Hydraulic Pump: If the hydraulic pump is not generating sufficient pressure, it should be replaced or repaired. Ensure the pump is in good condition to provide the necessary pressure for auxiliary hydraulics.
  
• Replace or Calibrate Sensors: Faulty sensors should be replaced, or if possible, recalibrated to ensure that the system is properly monitoring hydraulic pressure and flow.
  
• Clear or Replace Clogged Hydraulic Lines: If the hydraulic lines are clogged or restricted, they should be cleaned or replaced to restore proper fluid flow and system operation.
  

• Regularly Check Hydraulic Fluid: Periodically check the hydraulic fluid level and condition. Replace the fluid if it becomes contaminated or drops below the required level.
  
• Inspect Hydraulic Control Valve and Pump: Regularly inspect the hydraulic control valve and pump for signs of wear or malfunction. Ensure they are functioning correctly and replace any damaged components as needed.
  
• Inspect Electrical System: Perform routine checks on the electrical system, including fuses, relays, and wiring, to ensure proper operation of the auxiliary hydraulics.
  
• Check Hydraulic Lines: Regularly check hydraulic lines for leaks, blockages, or damage. Clean or replace lines as necessary to maintain proper fluid flow.
  
• Test Sensors: Periodically test the pressure and flow sensors to ensure they are functioning accurately and reliably.
