My trailer doesn't have TPMS. Its just a landscape trailer.
Basically the light would come on and the instrument panel said something about "low pressure". It did it non-stop from Friday morning until Sunday afternoon. Once the truck was started, it was on right away and stayed on the whole time. It originally started right after locking in the hubs that Friday morning and went out about an hour after unlocking them Sunday afternoon.
When I get the chance, I plan to do the process all over again: lock the hubs in and drive it to work or something. I work only 6 miles away so that should be ample distance to see if it does it again. Just no snow on the ground this time.
