I'll have to look this up

EXACTLY what im saying. once my tow dolly lights started working as normal. i could see on my infotainment screen that it was recognizing the trailer, etc. I tried tow haul mode and normal touring mode. But that didnt change anything, it was literally like the tow dolly was setting off the BLIS sensors...Shit was annoying, especially on a brand new truck that wasnt cheap

i've pulled this tow dolly with my previous truck and a buddies truck with zero issues... the lights have always worked completely fine. And no ice or snow, like you said...TX, lol

So, just bought a new 19' AT4. About a week old, few hundred miles already. Pulled my tow dolly to work thus morning( empty/unloaded) so that a buddy could come to borrow it. Firstly, hooking the 7 pin connection, the lights were on and off on the trailer...ended up not being on by the time i decided to not mess with it anymore(connector fully seated). So about 3 min driving down the road i notice the driver side blind spot warning light was staying on. Almost as though a car was in my DR side blind spot, which there wasnt. that lasted for about 2 min or so, then i get a warning pop up in the cluster saying the BLIS AND Lane keep assist features were being deactivated. The BLIS light goes away... then a couple min later... the passenger side BLIS light comes on and stays on... My tow dolly lights ended up coming on to and acting as normal. But the rest of the trip to work, no BLIS or LKA... they stayed off... very odd and very annoying. Haven't contacted the dealer yet, idk if somehow my trailer was in the BLIS field of view, which makes no sense... or somehow maybe some trash in the trailer connection making things go outta whack? any ideas? Gonna give it another go a different day and see what it does...

Traded in my 16' SLT and just got a new AT4. Love it so much more already, such a nicer truck
