1. 1

   Retrieve and verify the active codes using a diagnostic tool or interface device compatible with Massey Ferguson tractors

2. 2

   Consult the specific tractor's OEM service manual or a qualified technician to interpret the exact nature of the fault (e.g., whether it is a mechanical bind, a failed solenoid, or a wiring harness issue)

1. 1

   Inspect wiring harness

   Inspect the wiring harness to the valve.

2. 2

   Check sensor
