1. 1

   Cycle the in-cab hitch rocker switch off and on to 'wake up' the hitch system from safe/sleep mode

2. 2

   Inspect the external front hitch buttons for physical damage, sticking contacts, or water/mud ingress

3. 3

   Inspect the wiring harness and connector from the front hitch buttons to the HITCH controller for rub points, pinched wires, or corrosion

4. 4

   Use a multimeter to check the switch for continuity when pressed, and test the harness for an open circuit, short to ground, or short to power

1. 1

   Power Down

   Turn off the tractor, remove the key, and disconnect the battery to prevent electrical shorts during the repair.

2. 2

   Access the Switch

   Locate the external control buttons on the front hitch assembly.

3. 3

   Disconnect Wiring

   Reach behind the mounting bracket and carefully unplug the wiring harness connector from the faulty switch. Check the harness plug for corrosion and clean with contact cleaner if necessary.

4. 4

   Remove the Switch

   Depending on the exact switch style, depress the retaining tabs or remove the locking nut holding the switch in the bracket, and push the switch out through the front.

5. 5

   Install the New Part

   Push the new switch into the mounting bracket until it clicks securely into place.

6. 6

   Reconnect

   Plug the wiring harness back into the switch, ensuring the weather-tight seal is seated properly.

7. 7

   Test

   Reconnect the battery and start the tractor. Cycle the in-cab hitch rocker switch to activate the hitch system, then test the new external buttons to confirm the front hitch raises and lowers smoothly and the 09.03.02 code is cleared.
