I have this code and my research shows that the DSC module compares wheel speed sensor data to the steering angle using the logic that if the wheel speed sensors differ by a certain amount then the steering angle should vary by a certain amount becasue the vehicle is in a turn. That is how the 41 plausibility code is generated.

This is one of mine that has quite a few links about the DSC light:

This is my original thread:

EDIT: I thought I had linked to a TIS explanation of the steering angle operation in one of these threads but I can't find it now.

That explanation and function description that you posted was the one I remember reading last year. Very good information right there.
