1. 1

   Inspect the wiring harness, pins, and connectors leading to External Hydraulic Valve 2 for corrosion, moisture, or breaks

2. 2

   Check the spool position sensor on Valve 2 to ensure it is reading correctly and is not physically jammed or electrically shorted

3. 3

   Verify CANBUS communication between the dash/main controller and the valve module

1. 1

   Disconnect battery power

   Disconnect battery power before servicing the hydraulic electrical connections.

2. 2

   Locate External Hydraulic Valve 2

   Locate External Hydraulic Valve 2 at the rear remote stack (or mid-mount block, depending on tractor configuration).

3. 3

   Clean and reseat electrical connector

   Clean and reseat the electrical connector to the valve's solenoid and spool position sensor.

4. 4

   Replace sensor or valve slice

   If the wiring is intact but the spool position sensor value remains out of range, the sensor or the entire valve slice may need to be replaced.

5. 5

   Clear DTCs and verify

   Clear the DTCs using a compatible Massey Ferguson diagnostic tool and cycle the hydraulics to verify the fix.
