I just ran into this issue and the above tips were helpful, but they were not 100% correct.
In the Tool32 program for
steuern_stromwerte_vorgeben the argument needs to be:
The reason for this is there are 2 arguments - The first one is the axle... 0 is front, 1 is rear. Not sure why rear is even an option, maybe for cars with some kind of rear wheel steering? Either way, this needs to be 0. The second argument is whatever value you want to set for the angle. Of course we want 0 here to solve the issue. Then, ";" is the separator for the two arguments. I figured this out because its documented in Tool32 if you click on the command it actually explains what each argument is expected to be.
This was the only way I was able to get the EDC fault to go away after hours of messing with it.
