1. 1

   Use a compatible Massey Ferguson diagnostic tool to pull active codes and confirm 0A.61.27 is present

2. 2

   Inspect the wiring harness, connectors, and pins going to External Hydraulic Valve 6 for corrosion, damage, or loose connections

3. 3

   Consult the OEM service manual to pinpoint the exact physical location of Valve 6 on the rear hydraulic block

4. 4

   Perform multimeter tests on the valve's solenoid to check for electrical faults

1. 1

   Locate valve

   Locate External Hydraulic Valve 6 on the tractor's rear remote valve stack.

2. 2

   Clean electrical contacts

   Disconnect the electrical harness to the valve and clean the contacts. Reconnect and test to see if the code clears.

3. 3

   Remove valve assembly

   If the electrical connection is sound but the valve is leaking or failing to actuate, remove the spool valve assembly.

4. 4

   Rebuild or replace valve

   Depending on the severity of the failure, either rebuild the valve using an OEM spool valve repair kit or replace the entire spool valve assembly.

5. 5

   Reinstall and clear codes

   Reinstall the valve, bleed the hydraulic system if necessary, and use a diagnostic tool to clear the DTCs from the system.
