New Holland 4111 – ARU: Remote No.1 potentiometer faulty

The control module has detected an issue with the electrical signals from the potentiometer connected to the first remote hydraulic valve lever. The potentiometer translates the physical position of the control lever into a voltage signal. A fault indicates that this signal is out of the expected range, erratic, or absent, which can lead to the remote valve being unresponsive or behaving unpredictably.

1. 1

   Check the wiring and connectors between the remote lever in the armrest and the control module for any visible damage, corrosion, or loose connections

2. 2

   Identify the faulty lever by neutralizing the levers on startup; moving the lever for remote #1 may affect or clear the warning light, confirming it as the source

3. 3

   Check the diagnostic display for other active fault codes to rule out systemic issues like low battery voltage or a bad ground connection

1. 1

   Initiate calibration mode

   With the tractor engine off, turn the ignition key to the 'ON' position. Press and hold the timer switch located on the remote #1 valve until the timer light illuminates and the instrument panel displays a '1'.

2. 2

   Perform lever calibration

   Set the flow control knob for remote #1 to its maximum position. Move the control lever to its full 'raise' or 'extend' position and hold it until the display changes (e.g., to a '3'). Then move the lever to the full 'lower' or 'retract' position and hold it. If the fault was due to a loss of synchronization, the code should clear.

3. 3

   Access the armrest internals

   If calibration fails to resolve the fault, the potentiometer is likely faulty. Remove the armrest covers and panels to access the remote lever assemblies.

4. 4

   Remove the faulty potentiometer

   Locate the potentiometer attached to the base of the control lever for remote #1. Disconnect its electrical connector and unfasten any screws or clips holding it in place.

5. 5

   Install the new potentiometer

   Mount the new potentiometer, ensuring it is correctly oriented and mechanically engaged with the lever mechanism. Reconnect the electrical connector.

6. 6

   Reassemble and recalibrate

   Reassemble the armrest console. Perform the re-calibration procedure again to synchronize the new component with the control system.
