Ac activated my tss for the first time

My tss has never worked (have 2018) I tried many times to see if it would but finally said screw it ill mention it during the 5k mile oil change. Anyway the other night driving home on a completely empty freeway with clear weather I turned off my ac and the moment I did my dash screen turned red and make a noise and it said to brake, it scared the shit out of me because the first thing that popped into mind was did I do something with the 4wd (I think it's a very stupid design flaw to have it right next to ac knob)

Anyway I'm thinking when I bring it in they'll be like oh we can't find anything wrong with it or tell me to pound sand since I have the pro grille (OEM with OEM dealer garnish) tss never worked with the OR grille either

 

what did I just read?

How do you know TSS isnt working? Does your adaptive cruise control work? Does your lane warning assist not work? These are both really easy to test. Just because the truck hasnt been telling you to brake doesnt mean TSS is not working.

 

Mine told me to break when there was an officer on the side of the road, no one in front of me, but there he was and my dash lit up. First instance I knew the break assist tech was really working. Next time it did it I though my son was going to pass out, but it does work, just can't tell all the time. I know that it's two different trucks, but don't jump to the conclusion that it isn't working.
