New Holland 4109 – Rear Electronic Hydraulic Remote Valves (AUX): Rear Remote No. 1 – Manually Operated

The manual override for the number 1 rear electronic hydraulic remote (EHR) valve has been activated. This action disables the electronic control of the valve, preventing it from being operated by the in-cab controls such as the joystick or paddle. The code is generated because the control module detects that the valve has been placed in manual mode via a lever located directly on the valve body itself.

1. 1

   Check for other, more specific fault codes (e.g., 4110, 4111, 4112, 4113) to help pinpoint the root cause

2. 2

   Power cycle the tractor by shutting it down, waiting a few moments, and restarting, or toggle the master switch to clear potential intermittent electronic issues

3. 3

   Check the hydraulic fluid level to ensure it is correct, as low fluid can affect hydraulic component performance

4. 4

   Inspect the wiring harness and connectors leading to the number one rear remote valve for damage, corrosion, or loose connections

5. 5

   Attempt a valve calibration, as the electro-hydraulic remote valves can lose synchronization with the in-cab controls

1. 1

   Perform a valve calibration

   Access the tractor's diagnostic menu (often the 'H Menu') and initiate the calibration process for the electro-hydraulic remote (EHR) valves via the instrument cluster display.

2. 2

   Test in-cab controls

   Test the functionality of the control lever for remote #1. Swap connections with an adjacent remote to determine if the fault follows the lever (indicating a faulty control lever) or stays with the valve.

3. 3

   Inspect the remote valve assembly

   If in-cab controls are functioning correctly, inspect the valve assembly itself, including the control solenoid (driver) and internal potentiometer for position feedback.

4. 4

   Replace the remote valve section

   If the solenoid, driver, or internal sensor is faulty, replace the entire hydraulic rear remote control valve section for remote #1, as the electronic portion is often not sold separately from the mechanical valve body.
