New Holland NH 7024 – MFD/Diff Lock controller or MIU / Armrest controller: Steering angle sensor not calibrated

The machine's control system loses the stored calibration values for the steering angle sensor (which dictates the straight-ahead center position and the maximum left/right turning angles). This code is commonly triggered after the sensor has been replaced, disconnected, or if there has been a loss of memory in the controller.

• T6 Series (T6.120 to T6.175, T6010 to T6090)
• T7 Series (T7.170 to T7.270, T7.290, T7030 to T7070)
• T8 & T9 Series (T8.275 to T8.435, T8010 to T8050, T9.435 to T9.700)
• TM & TG Series (TM115 to TM190, TG210 to TG305)

1. 1

   Check for accompanying codes: Verify if codes NH 7031 or NH 7032 are also present. If 7024 is the only code, the sensor is likely functioning but needs recalibration.

2. 2

   Inspect the steering angle sensor (usually mounted on the front axle/steering cylinder area) for physical damage, loose mounting hardware, or a disconnected wiring harness.

3. 3

   Ensure the tractor is parked on a hard, level surface free of obstructions, and manually align the front wheels to the exact straight-ahead position for pre-calibration setup.

1. 1

   Position the Tractor

   Drive the tractor onto a hard, level surface and ensure the front wheels are perfectly straight.

2. 2

   Access Calibration Menu

   Using the tractor's in-cab display monitor (e.g., Intelliview) or an Electronic Service Tool (EST) / diagnostic laptop (like JPRO), navigate to the Steering Sensor Calibration or Auto Steer Setup menu.

3. 3

   Run the Calibration

   Follow the on-screen prompts. The procedure generally requires you to confirm the straight-ahead (center) position, and then turn the steering wheel fully to the left lock and fully to the right lock to register the maximum operating angles.

4. 4

   Clear the Fault

   Upon successful completion of the calibration, the steering angle sensor fault memory is usually cleared automatically. If it does not clear, manually clear the fault code via the display's FAULTS menu.

5. 5

   Test Drive

   Engage the Auto FWD/Diff Lock or auto-guidance system to ensure the tractor tracks straight and the code does not return.

6. 6

   Replace Sensor (if calibration fails)

   If the calibration fails repeatedly or the sensor voltage reads erratically during the process, the sensor itself is faulty and must be replaced, followed by this exact calibration procedure.
