1. 1

   Inspect the wiring harness connecting to External Hydraulic Valve 3 for any signs of damage, chafing, or a short circuit to earth.

2. 2

   Verify the signal voltage at the spool valve connector.

3. 3

   Check the external hydraulic valve control buttons (such as the mudguard switches or the multifunction armrest module) to ensure they are not stuck or internally shorted.

1. 1

   Connect a compatible diagnostic tool or interface device to the tractor to retrieve and confirm the active 0A.32.24 code.

   Confirm the active code before proceeding with repairs.

2. 2

   Perform the electrical diagnostic checks listed above on the #3 remote valve circuit.

   Check wiring, harnesses, signal voltage, and control switches.

3. 3

   If the wiring harness and control switches test good, the fault likely lies within the electro-hydraulic spool valve solenoid itself.

   Isolate the issue to the solenoid if electrical inputs are functioning correctly.

4. 4

   Replace the faulty External Hydraulic Valve 3 (or its solenoid, depending on the specific valve block design on your model).

   Refer to the specific tractor's OEM service manual for the exact torque specs and hydraulic pressure relief procedures before removing the valve.

5. 5

   Use the diagnostic tool to clear the DTCs and cycle the hydraulic remote to verify the repair.

   Ensure the code does not return and the remote operates normally.
