1. 1

   Inspect the hydraulic oil and transmission filters for dirt or blockages that can restrict oil flow and cause weak hydraulics

2. 2

   Inspect the solenoid connector, harness rub points, coil resistance, and ground integrity for connection problems

3. 3

   Check the spool position sensor value to ensure it is not reading out of range

4. 4

   Verify that there is communication between the Dash and the Mid Mount Valve Module

1. 1

   Locate valve

   Locate the External Hydraulic Valve 1 section on the tractor.

2. 2

   Remove module

   Remove the faulty valve module (the electronic unit located on top of the valve section).

3. 3

   Install module

   Install the replacement spool valve module.

4. 4

   Program module

   The new module must be programmed by a dealer or qualified technician so it is designated to the specific valve it is controlling.

5. 5

   Update software

   Ensure the software to the valves is updated during the programming process to ensure proper communication with the tractor's ECU.
