1. 1

   Inspect the wiring harness and connectors leading to External Hydraulic Valve 1 for connection problems

2. 2

   Check the spool position sensor circuit for damage, corrosion, or shorting

3. 3

   Verify proper communication between the Dash Control Center and the Valve Module

4. 4

   Clear the error code on the Dash Control Center and attempt to unlock the valves to see if the fault is hard-set

1. 1

   Retrieve and verify the active code (0A.13.18)

   Use a compatible diagnostic tool or the tractor's Dash Control Center.

2. 2

   Locate External Hydraulic Valve 1

   Find it on the tractor's hydraulic valve block.

3. 3

   Disconnect the battery

   Ensure safety while working on the electrical connections.

4. 4

   Disconnect the wiring harness

   Disconnect from the valve's spool position sensor and solenoids. Clean the contacts and check for continuity.

5. 5

   Remove the faulty spool valve assembly or spool position sensor

   Perform this step if the wiring is intact but the sensor/valve is failing.

6. 6

   Install the replacement valve/sensor

   Install the new component and reconnect the wiring harness.

7. 7

   Reconnect the battery

   Restore power to the tractor.

8. 8

   Clear the error code

   Turn on the tractor, navigate to the Dash Control Center, and clear the error code.

9. 9

   Manually unlock the valves and test

   Unlock the valves through the control interface and test the hydraulic function to ensure the issue is resolved.
