Massey Ferguson A.32.13 – Main vehicle ECU or Autotronic control module: External Hydraulic Valve 3 Issue

Issue description

Indicates a fault, connection problem, or out-of-range signal within the circuit controlling the third external hydraulic remote valve.

Inspect the electrical connector at External Hydraulic Valve 3 for corrosion, loose pins, or moisture.
Inspect the wiring harness for rub points, frayed wires, or damage along the path to the valve.
Measure the resistance of the valve's solenoid coil to ensure it is not open or shorted to ground.
Ensure the valve circuit has a solid ground connection.
Use a compatible diagnostic tool to clear the code and operate the tractor to see if the fault is a hard-set failure or an intermittent voltage issue.
