1. 1

   Inspect the wiring harness and connectors at External Hydraulic Valve 2.

2. 2

   Verify the spool position sensor values using a compatible diagnostic tool.

3. 3

   Ensure there is proper CAN communication between the tractor's Dash and the Mid Mount Valve Module.

1. 1

   Retrieve and clear codes

   Use a Massey Ferguson-compatible diagnostic interface to retrieve and clear the codes to see if 0A.21.11 is an active or stored fault.

2. 2

   Clean and reseat connector

   Clean and reseat the electrical connector on External Hydraulic Valve 2.

3. 3

   Replace sensor

   If the spool position sensor is reading out of range, replace the sensor or the sensor cap assembly.

4. 4

   Replace spool valve

   If the valve itself is mechanically stuck or the internal solenoids have failed, the spool valve section (mounted on the hydraulic lift cover or valve bank) must be removed and replaced.
