New Holland NH 1024 – Electronic Draft Control (EDC) module / Hydraulic Controller (Microprocessor): Perform Hydraulic Lift Autocalibration

The system requires a calibration routine to be run to relearn the operational parameters of the hydraulic lift system. This code is most commonly triggered after a component replacement, system service, or a memory reset.

1. 1

   Verify there are no other active fault codes related to the EDC system (specifically codes 1025, 1026, 1027, 1028, or 1029).

2. 2

   Ensure the Height Limit potentiometer is not incorrectly set, which can trigger a 'Code HL' and prevent calibration.

3. 3

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

4. 4

   Verify that the ground speed display reads exactly zero.

5. 5

   Disconnect all implements from the rear remotes and the 3-point hitch to ensure no load is on the lift arms during calibration.

1. 1

   Ensure all implements are disconnected and the tractor is safely parked as outlined in the diagnostic checks.

2. 2

   Make sure all Electro-Hydraulic Remote (EHR) program switches are in the OFF position.

3. 3

   Install the OEM diagnostic connector tool into the tractor's diagnostic socket.

   Install the OEM diagnostic connector tool into the tractor's diagnostic socket.

4. 4

   Access the diagnostic/calibration menu (often referred to as the 'H' menu routines) using the instrument cluster keys (e.g., 'h', 'm', and 'dimming' keys).

5. 5

   Navigate the menu to the Electronic Draft Control (EDC) calibration section (often H1 or H2) for the Lift Lever/Arm Potentiometers and EDC Valve Solenoids.

   Navigate the menu to the Electronic Draft Control (EDC) calibration section (often H1 or H2) for the Lift Lever/Arm Potentiometers and EDC Valve Solenoids. The lower central display will typically show 'CAL'.

6. 6

   Initiate the calibration sequence (on some models, this involves depressing the program switch for lever No.1 three times).

   Initiate the calibration sequence (on some models, this involves depressing the program switch for lever No.1 three times).

7. 7

   Allow the system to automatically cycle the hydraulic lift through its full range of motion.

   Allow the system to automatically cycle the hydraulic lift through its full range of motion. The controller will learn the minimum and maximum potentiometer values and the valve thresholds.

8. 8

   Once the display indicates the calibration is successful, save the settings, exit the diagnostic menu, and remove the diagnostic connector.

   Once the display indicates the calibration is successful, save the settings, exit the diagnostic menu, and remove the diagnostic connector. The NH 1024 code will clear.
