Check the cause
Check the hydraulic pump oil level and top up if necessary
Check the hydraulic oil for contamination
Listen to the system for clicking or loud noises; if heard, locate the source to determine if the pump, filter, or valve needs replacement
Check for spool position sensor value errors, which are common related faults in these systems

Refer to the specific tractor's service manual or consult with qualified technicians to interpret and address DTCs correctly.
Replace parts

Torque components
