CLAAS Id762Ah / 762Ah (411) – Transmission Module TR2 (A57-2): Steering System Calibration Procedural Error

Procedural error during the calibration of the tractor's steering system, indicating the 'wheel in line' (straight-ahead) position was not validated or saved by the operator/technician while configuring the steering angle sensor (B117).

• CLAAS Axion 850 - 810 series

1. 1

   Verify that the tractor is actively in the steering calibration mode.

2. 2

   Visually confirm that the front wheels are physically set to the exact straight-ahead position.

3. 3

   Ensure the differential lock button (which acts as the Enter/Validate key during this procedure) is functioning correctly and communicating with the module.

1. 1

   Set wheels straight

   Turn the steering wheel to set the front wheels perfectly straight (wheel in line position).

2. 2

   Validate position

   Validate this straight-ahead position by pressing the differential lock button.

3. 3

   Proceed to next calibration step

   Immediately proceed to the next step of the calibration to prevent subsequent faults (like Id762Bh): turn the wheels fully to the right and validate the right-hand mechanical stop position.

4. 4

   Return to normal mode

   Return to normal operating mode by pressing the differential lock button once the calibration sequence is complete.
