1. 1

   Visually inspect the Hitch Transport Dampening Button on the side console for physical damage or sticking.

2. 2

   Remove the console trim to access the back of the switch and check the electrical connector for loose pins, moisture, or corrosion.

3. 3

   Trace the wiring harness from the switch back to the HITCH module, testing for open circuits, high resistance, or a short-to-ground/short-to-power.

4. 4

   Use a multimeter to test the continuity of the switch itself; it should show a clear open/closed state when toggled. If resistance is erratic or infinite when closed, the switch has failed internally.

1. 1

   Power Down

   Turn off the tractor and disconnect the negative battery terminal to prevent electrical shorts.

2. 2

   Access the Switch

   Carefully pry up or unscrew the side console trim panel where the Transport Active Damping button is mounted.

3. 3

   Disconnect

   Unplug the wiring harness connector from the back of the faulty switch.

4. 4

   Remove

   Depress the retaining tabs on the sides of the switch body and push it upward out of the console bezel.

5. 5

   Install

   Snap the new Hitch Transport Dampening Button into the console bezel until it clicks securely into place.

6. 6

   Reconnect

   Plug the wiring harness connector into the new switch.

7. 7

   Reassemble

   Reinstall the console trim panel.

8. 8

   Clear Codes & Test

   Reconnect the battery. Use a compatible Massey Ferguson diagnostic tool to clear the 08.X.2B DTC. Start the tractor, raise the linkage, and press the Transport Active Damping button to verify the system engages without throwing a code.
