1. 1

   Inspect Electrical Connections: Check for a connection problem on the hydraulic valve harness. Look for damaged pins, corrosion, or loose connectors at External Valve 2.

2. 2

   Check Spool Position Sensor: Verify the spool position sensor value, as sensor failures are a common trigger for external valve issues.

3. 3

   Verify Module Communication: Ensure there is proper communication between the Dash and the Mid Mount Valve Module (if equipped).

1. 1

   Locate valve

   Locate External Hydraulic Valve 2 on the tractor's rear hydraulic remote block.

2. 2

   Disconnect harness

   Disconnect the wiring harness to the valve and the spool position sensor.

3. 3

   Inspect wiring

   Clean the contacts and inspect the wiring for breaks or shorts to ground.

4. 4

   Replace faulty component

   If the wiring is intact, the spool position sensor or the valve solenoid itself is likely faulty and requires replacement.

5. 5

   Clear DTCs

   After replacing the faulty component, use a compatible Massey Ferguson diagnostic tool or interface device to clear the DTCs from the system.
