New Holland EHR 4216 – EHR (Electronic Hitch/Hydraulic Remote) Controller: Rear Remote No.1 - Valve Spool Not Calibrated

This fault code indicates that the spool valve for the #1 rear electro-hydraulic remote has lost its calibration values or has never been calibrated. This commonly occurs after a software update, an ECU replacement, or if the physical remote valve has been replaced.

1. 1

   Check for Accompanying Codes: Look for other EHR codes (such as 4106 'Spool movement too low', 4118 'Under voltage', or 4111 'Potentiometer Faulty'). Fix hardware or voltage faults first.

2. 2

   Warm the Hydraulic Oil: Ensure the hydraulic oil is at operating temperature. Cold oil (below 5°C) can cause the spool to stick or move too slowly, causing calibration to fail.

3. 3

   Clear Debris: Stroke the #1 remote valve back and forth several times to clear any debris from the spool and purge air before attempting calibration.

4. 4

   Disconnect Implements: Never attempt to calibrate a remote valve with an implement attached.

1. 1

   Park the tractor on level ground away from obstacles, firmly apply the parking brake, and block the wheels.

   Ensure the ground speed display reads zero.

2. 2

   Disconnect all hydraulic hoses and implements from the rear remotes.

3. 3

   Ensure all EHR program switches/levers in the cab are in the OFF/Neutral position.

4. 4

   Install the diagnostic connector/special tool into the tractor's diagnostic socket.

   Use OEM tool #380001903 or #380000843.

5. 5

   Navigate the HH menu to H1 and select the rear EHR symbol on the controller.

   Use the instrument cluster keys (typically the 'h', 'm', and 'dimming' keys).

6. 6

   Verify the lower central display shows 'CAL'.

7. 7

   Depress the program switch for lever No.1 three times to initiate the calibration sequence.

   The tractor will automatically stroke the valve to learn the extend, retract, and neutral deadbands.

8. 8

   If the calibration fails the first time, stroke the valve manually back and forth for a few minutes to warm the oil further, then reattempt the calibration.
