New Holland ARMRE 59 – Armrest Controller: Aux 4th remote valve LEVER potentiometer is failed.
Issue description
The potentiometer (sensor) that reads the physical position of the 4th auxiliary hydraulic remote lever in the cab armrest has failed, has an open/short circuit, or is sending an out-of-range signal to the controller. This usually results in the disabling of that specific remote valve for safety.

Check the cause
Remove the armrest cover and inspect the wiring harness connecting to the 4th remote valve lever for pinched wires, chafing, or disconnected plugs.
Unplug the connector at the 4th remote lever potentiometer and check for bent pins, corrosion, or debris.
With the key ON, use a multimeter to verify that the potentiometer is receiving the standard 5V reference signal and has a good ground from the Armrest Controller.
If the wiring harness allows, temporarily swap the electrical connector from the 3rd remote lever to the 4th remote lever. If the fault code shifts to the 3rd remote, the potentiometer in the 4th lever is definitively internally failed.
Repair steps
Power Down
Turn off the tractor and disconnect the battery ground cable to prevent electrical shorts.
Access the Armrest
Remove the retaining screws holding the top cover/bezel of the armrest console to expose the remote lever modules.
Remove the Failed Lever
Disconnect the electrical harness from the 4th remote valve lever. Unbolt the retaining screws holding the specific lever assembly in place and pull it out of the armrest.
Install the New Part
Seat the new remote lever potentiometer assembly into the armrest slot, secure it with the retaining screws, and plug in the electrical connector.
Reassemble
Reinstall the armrest cover and reconnect the battery.
Calibration
Perform an Electro-Hydraulic Remote Valve Lever Calibration via the A-post instrument cluster display or IntelliView monitor. Cycle the lever fully forward to the float/extend position, and fully backward to the retract position so the Armrest Controller can learn the new minimum and maximum voltage values.

Specific part numbers vary heavily based on the exact tractor model and cab configuration. In many New Holland and Case IH armrests, the remote levers are modular and identical across the 1st, 2nd, 3rd, and 4th positions.
