Transfer case coding on E70

[Launch]

This issue might not be transfer case related at all. I suggest you let someone more experienced diagnose the real cause before starting part swapping.

i think your right. Replaced the transfer case and its still the same. Thinking its the ICM INTEGRATED CHASSIS MANAGEMENT CONTROL MODULE since it starts breaking when i try to accelerate and then the DTC kicks in and starts breaking and theres a issues with PDC as well and its all connected to it.

I would first check your tires. Correct sizes, all the same brand and model. When can't find an issue there, log wheel speeds when driving and when DTC activates. Check that the wheel speeds on front and rear axle are the same.

Tires are the same size but all 4 are different make I did the wheel speeds diagram and when driving the speed is same on all wheels, maybe just 1-3km/h variation and it only drops when DTC kicks in but it's showing that the wheels are spinning in reverse.
