Repair Procedure Summary

The root cause of this issue is identified as a software problem. The repair involves updating the steering column control module, J866, and performing a physical adjustment procedure. This process is outlined in TSB 2062288/5 and requires following instructions from TSB 2011732: 00 Software Version Management (SVM), operating instructions.

1. Software Update: Update the steering column control module, J866, using SVM action code 649S001. This update applies to models with Old Software Part Numbers 80A907705A (version 0100/0200) or 80A907705 (version 0080/0100), updating them to New Software Part Number 80A907705A (version 0210).
2. Restore Steering Column Function: To restore the electric steering column adjustment, an occupant must get into the vehicle and use their knees to push the steering wheel upward with approximately 40 kg (88 lbs) of force. Simultaneously, the steering column adjustment switch must be pressed upwards in the vertical adjustment direction.
3. Clear Adjustment Unit: The electric steering column adjustment must then be cleared by performing up to 50 adjustment cycles in the vertical direction. This step requires the use of a special tool kit.

Required Tools or Parts

To perform the adjustment cycles and clear the steering column unit, technicians will need:

• Tool Kit T10230: This assembly tool weighs approximately 9 kg (20 lbs) and is necessary to simulate the required weight for the adjustment process. If the tool kit T10230 is not available in the workshop, technicians are advised to look for a similar weight toolbox.

Important Warnings

• Tool Kit T10230 Alternative: If the tool kit T10230 is not available in the workshop, look for a similar weight toolbox to ensure the procedure can be completed correctly.
