I ordered mine off eBay and they sat in my glove box for weeks. Had them installed today. When I hooked the truck up and setup the trailer profile it prompted me to program tpms. Said I could do it manually or with tpms tool. I decided to try manually. Pressed start and went in order letting air out of each tire for at least 10 sec. got back in the cab and it was done.

I got all mine on eBay. I got six for probably about the same price as two from the dealer. Only question I have and maybe somebody knows the answer is.... Are there batteries on them that I can change?

Yep

Never mind found it myself. Mine has the module so I should be good to go

does Anyone have a picture of said U1D module that’s behind the rear license plate. I have a module behind mine but not sure if it’s the correct one. When I do a trailer setup in my trailering app it has maintenance reminders and check list but see nothing about security or tire pressure sensors.

So this isn’t included with the Denali ultimate package? Was actually getting ready to set mine up. I purchased sensors online but not sure if I have the module. Anyone have a part number for the module. Is it just plug and play or does the dealership have something to do?
