1. 1

   Inspect the wiring harness and electrical connector at External Hydraulic Valve 5 for corrosion, bent pins, or wire chafing

2. 2

   Check the mechanical and electrical spool valve control cables for binding or damage

3. 3

   Use a diagnostic tool to monitor the live voltage and status of Valve 5, and attempt to clear the code to determine if it is a hard fault or an intermittent issue

1. 1

   Locate valve

   Locate External Hydraulic Valve 5 in the rear hydraulic remote stack.

2. 2

   Disconnect battery

   Disconnect the battery to prevent electrical shorts.

3. 3

   Disconnect harness

   Disconnect the electrical harness from the valve solenoid/actuator.

4. 4

   Remove valve

   If the valve is leaking or internally bypassing, remove the mounting bolts securing the valve to the hydraulic block.

5. 5

   Replace seals

   Replace the spool valve O-rings/gaskets (using a spool valve gasket kit) if the issue is a pressure leak.

6. 6

   Replace valve assembly

   If the electronic actuator or the valve itself has failed, replace the entire External Hydraulic Valve 5 assembly.

7. 7

   Reinstall valve

   Reinstall the valve, torque the mounting bolts to OEM spec, and reconnect the electrical harness and spool valve cable.

8. 8

   Finalize repair

   Reconnect the battery, top off hydraulic fluid if any was lost, and use a diagnostic tool to clear the 0A.51.13 code. Test the remote for proper operation.
