1. 1

   Retrieve active codes using a compatible Massey Ferguson diagnostic tool to confirm if 0A.21.2A is active or stored, and check for accompanying spool position sensor codes (e.g., M17, M18, M19).

2. 2

   Inspect the electrical harness and connectors leading to External Hydraulic Valve 2 for connection problems or damage.

3. 3

   Verify the sensor values for the spool position sensor to ensure it is reading the physical position of the valve correctly.
