1. 1

   Inspect the wiring harness, pins, and connectors leading to External Hydraulic Valve 6 for corrosion, loose fittings, or breaks.

2. 2

   Retrieve and verify the active codes using a diagnostic tool or interface device compatible with Massey Ferguson tractors to ensure no other supplementary codes are present.

3. 3

   Consult the specific tractor's service manual to interpret the exact voltage or resistance values expected at the valve harness.

1. 1

   Locate External Hydraulic Valve 6

   Locate External Hydraulic Valve 6 (often part of the electric spool slice assembly at the rear remotes).

2. 2

   Test and repair wiring

   Test and repair any damaged wiring or connection issues at the valve.

3. 3

   Replace the electric spool slice/valve

   If the electrical connections are sound, the electric spool slice/valve itself has likely failed internally and must be replaced.

4. 4

   Program the new unit

   If replacing an electric spool slice (such as part 3797234M6), the new unit will need to be programmed to the tractor's onboard computer.
