1. 1

   Check the CAN bus wiring on the transmission bus wiring harness for breaks, corrosion, or short circuits (refer to Wiring Diagram Sheet 39)

1. 1

   Prepare tractor for calibration

   Ensure the tractor is parked safely, the handbrake is applied, and the front wheels are perfectly straight.

2. 2

   Enter calibration code

   Access the tractor's terminal and enter Calibration Code 2403 (Autoguide steering valve calibration).

3. 3

   Start calibration

   Press the button to start the calibration process.

4. 4

   Observe safety precautions

   The calibration runs automatically. Do not touch or move the steering wheel, and do not leave the driver's seat (the seat contact switch must remain engaged). Warning: The front wheels may move slightly to the left and right on their own during this process.

5. 5

   Verify calibration success

   If the calibration is successful, the terminal will display 'OK'. If conditions are not met or a mechanical fault exists, it will display 'ERROR'.

6. 6

   Save calibration values

   To save the new calibration values, turn the ignition key to the '0' (Off) position and wait for at least 15 seconds before turning the tractor back on.
