New Holland 4180 – ARU / TMF: Rear Remote Control Valve No. 4 - Not Calibrated

The electronic rear remote hydraulic valve number 4 has lost its calibration settings. The control system does not know the precise position of the valve's spool, which affects its proper operation and functionality. The valve may still operate, but its response to controller inputs will be incorrect until a successful calibration is performed to re-synchronize the control lever with the valve spool.

1. 1

   Ensure the tractor's hydraulic oil is warmed to at least 49°C (120°F), as cold oil can affect the calibration process

2. 2

   Check the diagnostic menu for other active fault codes related to the armrest controller or CAN bus communication that could interfere with calibration

3. 3

   Verify that the main Armrest (ARM) and Instrumentation (INST) controllers are calibrated (required on some models before calibrating remote valves)

4. 4

   Inspect the wiring harness and connectors between the armrest controller, valve controller, and the No. 4 remote valve for visible damage, corrosion, or loose connections

5. 5

   Manually stroke the valve back and forth several times to clear any debris that may be obstructing the spool's movement

1. 1

   Prepare tractor for calibration

   Park the tractor on level ground, engage the park brake, and stop the engine. Ensure no implements are attached to the valve and any existing implements are in a safe position.

2. 2

   Enter calibration mode (Instrument Panel Method)

   Turn the ignition key to the 'ON' position without starting the engine. On the No. 4 remote valve, press and hold the timer switch until the timer light illuminates and the display shows a '1'.

3. 3

   Perform valve calibration sequence

   Wait for the timer light to go out and a '2' to appear on the display. Set the flow control knob for valve #4 to its maximum position. Move the remote valve control lever to the full 'raise' or 'extend' position. The timer light will illuminate again.

4. 4

   Finalize and save calibration

   Wait for the light to extinguish and a '3' to appear, indicating the step is complete. Follow any further display prompts (typically ending with 'END'). Turn the key to the 'OFF' position and wait at least 10 seconds to store the new settings.

5. 5

   Alternative calibration (Special Tool Method)

   If the instrument panel method is not applicable, connect diagnostic tool Part No. 295041 or 380001903 to the black diagnostic connector. Turn key 'ON', access the 'H' menu then the 'H1' calibration menu, select valve No. 4, press the program key, and move the lever to the maximum extend detent to initiate. On some models, operate the valve timer switch three times quickly to activate the procedure. Turn key 'OFF' when complete to store values.
