1. 1

   Use a compatible diagnostic tool or interface device to confirm 0A.73.11 is the active code

2. 2

   If equipped with a Datatronic 5 terminal, navigate to the hydraulics page (via the three bars in the top right corner) to check the status, flow settings, and naming of Valve 7

3. 3

   Physically inspect the wiring harness, pins, and connector plugging into External Hydraulic Valve 7 at the rear remote block for corrosion, backed-out pins, or wire chafing

1. 1

   Disconnect battery

   Disconnect the battery to ensure safety while working on the tractor's electrical and hydraulic systems.

2. 2

   Locate valve

   Locate External Hydraulic Valve 7 on the rear hydraulic remote stack.

3. 3

   Clean contacts

   Disconnect the electrical connector to the valve's solenoid. Clean the contacts with electrical contact cleaner and apply dielectric grease.

4. 4

   Repair wiring

   If the wiring is damaged, repair or replace the pigtail/harness section.

5. 5

   Replace valve assembly

   If the electrical connection is sound but the code persists, the electronic spool valve assembly or its solenoid has likely failed internally and must be replaced.

6. 6

   Clear DTCs and test

   Clear the DTCs using a compatible Massey Ferguson diagnostic tool and test the hydraulic remote for proper operation.
