New Holland 4112 – ACM: Rear Remote Control Valve No. 1 - Impossible to Reach Neutral Position

The control system has detected that the spool for the rear electro-hydraulic remote (EHR) valve number 1 is not in the neutral position when commanded. This indicates the valve spool is stuck partially or fully open, causing continuous hydraulic flow. This condition prevents an attached implement from holding its position and keeps the hydraulic pump under continuous load.

1. 1

   Verify the joystick or lever for remote #1 is physically in the neutral position and not stuck or obstructed

2. 2

   Attempt to recalibrate the electronic remote valves, as an error in stored calibration values is a common cause

3. 3

   Inspect the wiring harness, CAN bus connections, and solenoid connectors at the #1 remote valve block and armrest controller for damage, corrosion, or loose connections

4. 4

   Check hydraulic fluid for clarity and ensure filters are not clogged, as contamination can cause valve spools to stick

1. 1

   Recalibrate the remote valve

   Stop the engine, turn the key to the 'on' position, and navigate to the H1 menu or calibration setting (or depress the timer switch on the valve while turning the key on). Follow on-screen prompts to move the control lever to full extend and retract positions to teach the controller the range of motion.

2. 2

   Test valve solenoids

   If calibration fails, swap the electrical solenoid from valve #1 with a known working one from another remote (e.g., remote #2). If the fault code moves to the other remote (e.g., 4114), replace the faulty solenoid.

3. 3

   Rebuild the valve section

   If the fault remains on remote #1 after swapping solenoids, the spool is likely sticking due to internal seal failure. Disassemble the valve stack in a clean environment and replace all seals and O-rings using a hydraulic valve seal kit.

4. 4

   Replace the remote valve

   If the valve body or spool is scored or damaged, or if a rebuild is not feasible, replace the entire rear remote hydraulic valve section.
