1. 1

   Inspect the wiring harness, pins, and connectors leading to External Hydraulic Valve 6 for corrosion, looseness, or damage

2. 2

   Retrieve the active codes using a compatible Massey Ferguson diagnostic tool or interface device to confirm if the fault is intermittent or hard-set

3. 3

   Refer to the tractor's specific service manual to interpret the exact nature and physical location of Valve 6 on the specific chassis before tearing down the hydraulic block

1. 1

   Verify code

   Connect a compatible diagnostic tool to the tractor to verify code 0A.62.18 is active.

2. 2

   Locate valve

   Locate External Hydraulic Valve 6 on the rear remote block.

3. 3

   Inspect and clean connector

   Disconnect the electrical connector to the valve's solenoid and inspect for a connection problem. Clean the contacts and re-seat the connector.

4. 4

   Replace faulty component

   If the wiring is intact but the code persists, the hydraulic valve solenoid or the external hydraulic valve control assembly itself is likely faulty and requires replacement.

5. 5

   Depressurize system

   Consult with a qualified technician or the specific model's service manual to safely depressurize the hydraulic system before unbolting the valve or solenoid.

6. 6

   Install and clear codes

   Install the replacement solenoid/valve, reconnect the harness, and clear the DTCs using the diagnostic interface.
