I have a 2022 Sierra 1500 AT4 3.0 and it has the module installed behind the license plate from the factory, truck did not come with the extra sensors for a trailer though.
In my trailering app I don’t see anything at all for TPMS. For those of you that are able to see trailer TPMS do you always have something visible in your trailer app, or only when connected to a trailer that has TPMS installed?
Curious if I added TPMS sensors to my trailer if I would be good to go or not. I see many appear to need a new radio but it seems odd to me that I would need that if the module is already installed on the truck when it was built.
