I happened to check my techstream today and noticed the same thing. I believe it the damper is set to stiff for safety ( in case of being rear ended).
I noticed on my car that the damper never goes below 5. Do you see damper settings of 1 during cruising?
In sports setting, the the dampers are set to 11 with some 9's from time to time.
whenever you have DTC's, you will have 17 as default.
thank you.
