1. 1

   Use a compatible diagnostic tool or interface device to confirm the 0A.32.25 code is active

2. 2

   Locate External Hydraulic Valve 3 on the rear remote valve block for visual inspection

3. 3

   Thoroughly inspect the electrical connector and wiring harness leading to Valve 3 for corrosion, backed-out pins, or physical damage

1. 1

   Power Down

   Turn off the tractor and disconnect the battery to ensure safety while working on the electrical/hydraulic systems.

2. 2

   Inspect and Clean

   Disconnect the electrical harness from External Hydraulic Valve 3. Clean the contacts using electrical contact cleaner and check for any broken wires in the pigtail.

3. 3

   Re-seat Connection

   Firmly reconnect the harness, ensuring the locking tab clicks into place.

4. 4

   Test Solenoid

   If the wiring is intact, test the valve's solenoid for proper resistance (ohms) according to the specific model's service manual.

5. 5

   Replace Component

   If the solenoid is shorted/open, or if the valve spool is mechanically seized and unresponsive to electrical commands, replace the solenoid or the entire valve section.

6. 6

   Clear Codes

   Reconnect the battery, power on the tractor, and use a compatible diagnostic tool to clear the DTC. Cycle the hydraulic valve to ensure the code does not return.
