Case IH 1068 – EDC (Electronic Draft Control) module: Draft control calibration aborted due to tractor moving

The tractor's control module detected movement (via the wheel speed sensors, transmission output speed sensors, or radar) while the operator was attempting to calibrate the 3-point hitch or Electronic Draft Control (EDC). Calibration requires the tractor to be completely stationary. If the tractor is parked but the code still triggers, it means the controller is receiving a false speed/movement signal, which can sometimes be caused by external electromagnetic interference (EMI).

1. 1

   Verify the tractor is parked on a completely level surface with the parking brake engaged

2. 2

   Check the immediate area for external electromagnetic interference (EMI) such as high-voltage transformers, welding machines, or radio broadcast towers

3. 3

   Ensure there is absolutely no load or implement attached to the 3-point hitch, and that the linkage can move freely through its entire operating range without binding

4. 4

   Monitor the wheel speed and radar sensor inputs using the Pro700/A-post display or a diagnostic tool while the tractor is parked (a speed value greater than zero indicates a sensor or harness fault)

5. 5

   Inspect the wiring harnesses and connectors for the wheel speed sensors and radar for damage, corrosion, or loose connections

1. 1

   Relocate the Tractor

   Move the vehicle away from any potential sources of electromagnetic interference (EMI) to rule out environmental factors.

2. 2

   Prepare for Calibration

   Park the tractor on a level surface, engage the parking brake, and ensure the tractor is completely stationary. Remove any implements from the 3-point hitch.

3. 3

   Set Engine Speed

   Set the tractor engine to the specified speed (usually low idle, unless the display prompts otherwise).

4. 4

   Attempt Calibration

   Restart the EDC / Hitch calibration procedure via the Pro700/A-post display or the calibration switch.

5. 5

   Address Sensor Faults

   If fault code 1068 persists and the tractor is definitely not moving, locate the wheel speed sensor(s) and/or radar sensor. Disconnect the sensor harness and inspect the pins for corrosion or moisture.

6. 6

   Replace Faulty Sensors

   If the wiring is intact but the sensor continues to send a false movement signal to the ARM/EDC module, replace the faulty wheel speed sensor or radar unit.

7. 7

   Finalize

   Clear the inactive fault codes and perform the hitch calibration procedure again to verify the repair.
