How to resolve the 4X4 malfunction in BMW X6?

[GrahamLynn]

Attempting to input hierarchical data was successful, but debugging remains impossible, indicating that a certain system in the vehicle is still affecting the VTG. The failure to input the classification value for 5225VTG category resulted in the issue; the "5F3ADSC transfer case malfunction" is due to the missing 5225VTG category. The 6428ICMVTG interface malfunction caused the ICM to lack VTG information, hence the ICM cannot calibrate the central dynamic driving adjustment. The 6428ICMVTG interface issue can be resolved through trial operation of QMVH, where QMVH represents rear axle lateral torque distribution.
