1. 1

   Inspect the rocker switch on the side console/armrest for physical wear, sticking, or debris preventing full contact.

2. 2

   Use a multimeter to verify voltage at the switch terminals and check for continuity when the switch is toggled up and down.

3. 3

   Trace the wiring harness from the switch to the HITCH module under the seat. Look for pinched wires, shorts, or corrosion at the connector pins.

4. 4

   Manually push the override buttons on the rear hydraulic valve block solenoids to rule out a mechanical or hydraulic failure. If the hitch raises and lowers manually, the issue is isolated to the switch, wiring, or the HITCH module itself.

1. 1

   Turn off the tractor ignition and disconnect the battery

   to prevent electrical shorts.

2. 2

   Carefully pry up or unscrew the side console/armrest panel

   to access the underside of the hitch control switches.

3. 3

   Mark and disconnect the electrical wiring harness connector

   from the faulty raise/lower rocker switch.

4. 4

   Squeeze the retaining clips on the sides of the old switch

   and push it up and out of the console panel.

5. 5

   Snap the new OEM rocker switch

   into the panel.

6. 6

   Reconnect the electrical connector

   ensuring it is fully seated and secure.

7. 7

   Reinstall the console panel

8. 8

   Reconnect the battery and turn on the ignition

   Clear the stored error codes from the diagnostic display.

9. 9

   Cycle the rear hitch up and down several times

   to verify proper operation and ensure the system is communicating correctly.
