1. 1

   Use a compatible diagnostic tool or interface device to pull the active DTCs and confirm 0A.71.1F is present

2. 2

   Thoroughly inspect the wiring harness, electrical connectors, and pins leading to External Hydraulic Valve 7 for corrosion, damage, or loose fittings

3. 3

   Inspect the electric spool slice and the pilot pressure control for the electric spool valve for physical damage or electrical shorts

1. 1

   Connect a compatible diagnostic tool to the tractor to verify the fault code.

2. 2

   Locate the external hydraulic valve block at the rear of the tractor and identify Valve 7.

3. 3

   Disconnect the electrical connector to the valve and inspect for faults. Repair or replace any damaged wiring.

4. 4

   If the wiring is intact, the electric spool slice (valve) itself or its pilot pressure control is likely faulty and must be replaced.

5. 5

   Install the new electric spool slice.

   Note: Replacement electric spool slices must be programmed to the tractor's system to function correctly.

6. 6

   Use the diagnostic tool to clear the DTCs from the system.

7. 7

   Test the hydraulic remote to ensure optimal performance and verify the code does not return.
