I don't think you (we) have ACC, I'm sure I don't... Maybe the 17 Denali but I don't think so ??? looks like only the SUVs

I know on Etrailer the baseplate info for the twins designates with and w/o ACC.
The part numbers are the same
I use the Blue ox 1721 when installing there was nothing in the front facia indicating a ACC or other sensors except the ambient air temp which had to be r&r to the base plate
I believe all sensors for the lane departure, forward collision, etc are in the rear view mirror
Do a site search using "canyon Colorado" regarding toad info
I and many others have posted a ton of info regarding towing the 2015-2017 4wd twins
