Case IH 7024 – Instrumentation Controller (INST) or Auto Guidance / NAV Controller: Steering angle sensor not calibrated

The steering angle sensor monitors the rotational position of the front steering axle and transmits real-time position data to the auto-guidance system. When this code is active, the controller has lost the zero-point or end-stop calibration values for the front axle, which disables Auto Guidance / Auto Steer and can affect electronic stability systems.

1. 1

   Verify that the steering angle sensor (located on the front steering axle/kingpin) is physically intact.

2. 2

   Inspect the sensor's mechanical linkage and rods for bending, damage, or excessive play.

3. 3

   Check the wiring harness and connector at the sensor for corrosion, moisture, or broken wires.

4. 4

   Look for associated out-of-range fault codes (such as 7031 'Steering angle sensor out of Maximum range' or 7032 'Steering angle sensor out of Minimum range'). If these codes are present, the sensor is likely defective rather than just uncalibrated.

1. 1

   Ensure the tractor is parked on a flat, level surface with the engine running.

   Ensure the tractor is parked on a flat, level surface with the engine running.

2. 2

   Access the calibration menu through the tractor's display (e.g., AFS Pro 700 monitor) or the instrument cluster.

3. 3

   Navigate to the Auto Guidance / Wheel Angle Sensor calibration section.

   Navigate to the Auto Guidance / Wheel Angle Sensor calibration section.

4. 4

   Follow the on-screen prompts.

   The standard procedure generally requires turning the steering wheel fully to the left steering lock, acknowledging the position, then turning fully to the right steering lock, acknowledging, and finally returning the wheels to the exact straight-ahead center position.

5. 5

   Save the calibration.

   Save the calibration.

6. 6

   Test the Auto Guidance system.

   If the calibration repeatedly fails, the code returns immediately, or the steering position feedback remains erratic, the sensor itself has failed and must be replaced.

7. 7

   If replacing the sensor, install the new unit, ensure the mechanical linkage is set to the correct length, and repeat the calibration procedure.
