1. 1

   Inspect the LED indicators on the electronic valves (solid red indicates power, green indicates an input command, and flashing confirms a localized fault on Valve 2)

2. 2

   Verify the physical position of the external linkage and ensure the valves are returning to the center/neutral position

3. 3

   Access Autotronic diagnostics via the tractor screens to check DC and TC error codes for specific spool position sensor values or communication drops

4. 4

   Check the hydraulic valve harness for connection problems or communication drops between the dash and the mid-mount valve module

1. 1

   Modify detents

   Source detents for the 7600 series and modify them to fit as a cost-saving alternative to replacing the entire valve assembly if the mechanical detents are worn.

2. 2

   Replace valve

   Replace the entire Electric Spool Slice if the electronic slice or internal spool has completely failed.

3. 3

   Program valve

   Program the new electric spool slice to the tractor using dealer diagnostic software so it functions correctly.
