New Holland 4117 – MIU: Rear Remote No. 2 Not Neutral on Power-Up

The Electronic Hydraulic Remote (EHR) control module has placed the number 2 rear remote hydraulic valve into a 'safe mode'. This protective measure occurs when the system fails to detect a command for the valve to be in the neutral position during the tractor's power-on sequence. Because the controller expects a neutral state signal at startup, a missing or incorrect signal flags this fault and disables the valve to prevent unexpected or dangerous operation of connected hydraulic equipment.

1. 1

   Check for operator error: Ensure the operator is moving the control lever for remote #2 to its center/neutral position at startup to clear any 'neutral the lever' messages.

2. 2

   Check the hydraulic fluid level and condition, as low or contaminated fluid can cause hydraulic issues.

3. 3

   Inspect for any visible hydraulic fluid leaks around the remote valve stack and hoses.

4. 4

   Inspect the wiring and connectors leading to the #2 remote valve solenoid and the control lever/potentiometer in the armrest for looseness or corrosion.

5. 5

   Swap components (like solenoids) with another identical remote to see if the problem moves, helping isolate the faulty part.

6. 6

   Attempt to recalibrate the remote levers through the tractor's display (A-post monitor) to resolve issues where the sensor's neutral position has drifted.

1. 1

   Recalibrate remote levers

   Attempt to recalibrate the remote levers through the tractor's corner post display (A-post monitor). Access the calibration menu, select the remote valve calibration, and follow the on-screen instructions. This may require a special tool for some models.

2. 2

   Inspect or replace control lever/potentiometer

   If calibration fails, disassemble the armrest to access the remote levers. Test the potentiometer with a multimeter for incorrect resistance readings. Replace the entire lever assembly if worn or faulty.

3. 3

   Inspect remote valve spool and solenoid

   If the lever is functioning, check the hydraulic valve itself. Verify the spool is not physically stuck due to debris or internal wear. Check the solenoid for proper voltage and operation.

4. 4

   Check valve detent mechanism

   Inspect the detent mechanism of the valve. Repair or replace if rusted or damaged, as this can prevent the spool from returning to neutral.

5. 5

   Update software

   Check with a dealer to see if any software updates are available for the hydraulic control module.
