1. 1

   Use a diagnostic tool or interface device compatible with Massey Ferguson tractors to confirm the active DTC.

2. 2

   Inspect the wiring harness and the electrical connector at External Hydraulic Valve 4 for corrosion, backed-out pins, or wire chafing.

3. 3

   Consult the tractor's specific service manual to interpret the exact electrical values expected at the valve solenoid.

1. 1

   Locate valve

   Locate the rear hydraulic valve stack and identify External Valve 4.

2. 2

   Disconnect connector

   Disconnect the electrical connector to the valve's solenoid.

3. 3

   Clean and repair wiring

   Clean the contacts and repair any damaged wiring in the pigtail harness.

4. 4

   Replace valve

   If the wiring is intact but the code persists, the electric spool slice/solenoid has likely failed internally and must be replaced.

5. 5

   Clear DTCs

   After replacing the valve slice, use a diagnostic tool to clear the DTCs from the system. Note: Some replacement electric spool slices require programming/calibration to the tractor after installation.
