1. 1

   Inspect the wiring harness, electrical connector, and pins at External Hydraulic Valve 3 for corrosion, damage, or loose connections

2. 2

   Connect a compatible diagnostic interface device to the tractor's diagnostic port to read the active/inactive status of the code and perform component tests on the valve

3. 3

   Consult the tractor's operator or service manual for guidance on clearing error codes, as some simpler codes may have manual reset instructions

1. 1

   Relieve pressure

   Relieve all hydraulic system pressure before starting work.

2. 2

   Locate valve

   Locate External Hydraulic Valve 3 (typically mounted on the rear remote valve stack).

3. 3

   Inspect harness

   Disconnect the electrical harness to the valve solenoid and inspect for faults.

4. 4

   Diagnose internal fault

   If the wiring is intact and receiving proper voltage, the valve solenoid or the valve block itself may be internally faulty.

5. 5

   Replace component

   Remove the retaining hardware and replace the faulty hydraulic valve or solenoid.

6. 6

   Reconnect harness

   Reconnect the wiring harness.

7. 7

   Bleed and clear code

   Bleed the hydraulic system if necessary and use a diagnostic tool to clear the 0A.31.13 code.
