New Holland 4106 – Hydraulic or Armrest Control Module: Rear Remote Valve 1 Insufficient Spool Movement

The electronic control module has commanded the spool of the number 1 rear remote hydraulic valve to move, but the spool has not traveled the expected distance. The controller monitors the position of the valve spool, and triggers this code if the commanded movement does not correlate with the actual movement detected by the sensor. This insufficient movement may affect the proper operation of the connected hydraulic system and can be caused by a physically stuck spool, a faulty spool position sensor, or system calibration issues.

1. 1

   Check for manual override: Ensure that the manual override lever on the valve body has not been activated, as this will disable electronic control.

2. 2

   Inspect wiring and connections: Visually inspect the wiring harness and connectors leading to the number 1 rear remote valve for any signs of damage, corrosion, or loose connections.

3. 3

   Check hydraulic fluid: Ensure the hydraulic fluid level is adequate and the fluid is clean, as contaminated fluid can cause valve spools to stick.

4. 4

   Review other fault codes: Check for any other active fault codes that might indicate a broader electrical or communication issue on the CAN bus network.

1. 1

   Recalibrate the remote valve

   Perform a calibration of the electronic remote valves to resynchronize the control lever with the valve spool. Initiate this through the tractor's instrument panel display (may require special tool No. 295041 connected to the diagnostic port).

2. 2

   Test the control lever potentiometer

   Swap the electrical connectors between the faulty remote lever and a functioning one. If the fault follows the lever, the potentiometer is defective and sending incorrect position signals to the controller.

3. 3

   Inspect the valve spool

   If calibration and lever diagnostics do not resolve the issue, the valve spool itself may be sticking due to debris or mechanical wear. Remove, disassemble, clean, and inspect the valve for damage.

4. 4

   Check the spool position sensor

   Test the spool position sensor's output to ensure it is providing a correct and stable signal. Replace the sensor if it is determined to be faulty.

5. 5

   Inspect the hydraulic compensator valve

   On specific models like the T6 and T7, check the hydraulic compensator valve on the pump. A sticking compensator valve can lead to sluggish hydraulic performance related to this fault.
