TPMS for trailers

My 2019 Sierra SLT came with a set of TPMS valves for my trailer, and I finally got them installed.  Local garage used their tool to "learn" the positions and everything worked fine.  Having TP and wheel temp from the trailer was nice!

 

Worked all the way home, but next time I turned on the truck and hooked up the trailer, the TPMS system was reset, and it needed to be configured again!  I set it up using a manual method, and everything seemed set up correctly, however same problem. Turned the truck off and on again, and all the settings were erased.

 

I won't be able to get to my dealer for a while to make them fix this, so I was wondering if anyone has run into this, and knows what I might be doing wrong, or what the fix is?

 

Like everything else these days, its probably a software glitch... *sigh*

Interesting.  I had mine installed a couple of months ago and have had zero problems.  I used a learn tool that I got off of Amazon for $15.  My next step would be to have the dealer reflash your truck's computer module.  I'm assuming you have created a trailer profile and followed all the programming steps in the owner's manual, otherwise it wouldn't have worked to begin with.  So, for whatever reason, your truck is dumping the retained memory every time.

That happened to me the first time when discount tire finished installing the sensors.  I came home and used the manual method, no issues since

Hooked up the trailer to go to the dealer and voila TPMS is working again.

Two days later on the road, numerous on/off cycles and still ok.

Seems gremlins in software are gone!

      I am sure that was quite the pass experience and not a great place to experience during the winter when the conditions are not good. I've seen video of that pass and also more detailed information and pictures about the wrecks at that one hair pin turn where tractor trailers have flown right off the cliff and I am sure from all the warning signs that you know the exact curve that was !. After all there is a reason why a song was made about Wolf Creek Pass !. By the way and I didn't realize this either when I bought my truck as its nothing I even thought of that would be programmed into the cruise control and this occurs in either the basic or the more advanced cruise that controls your distance behind a vehicle and that is the brakes going down a hill are being applied as soon as the vehicle goes a certain speed over the set cruise speed. While it certainly does force downshifts in the transmission as you found out with cruise on while going down hill, its also dragging the brakes as needed to keep the speed controlled to what the cruise was set to. For me, I find that unsettling simply because I have no concept then as to how MUCH brake input is being used a and just how hot are those brakes getting and the wear factor as well. I can see that system getting a person into trouble on long mountain grades while pulling a trailer as it would not only be standing on the brakes of the pickup without any driver input, it would also be automatically applying the trailer brakes and it could cause a run away unit by overheating the brakes. Its one thing on a shorter hill and if the driver allows it to do its thing but on a long mountain grade is where things could get so out of hand. As someone a while back on this forum said, they had someone following them at night I believe on a down grade and had the cruise set and the person behind them could see the brake lights being energized all the way down the hill. I figured when I saw your comment that you didn't know and would have no way of knowing that your truck was applying the brakes and that you would and rightfully so assume you only used the brakes when you pressed on the pedal to slow down more than the cruise set speed for the slower sharp curves. So its good knowledge to know this about the newer GM trucks, certainly when doing any descending on long mountain grades. In the future try kicking off the cruise and use the the manual mode on a pass to see what that is like as I know myself when I first experienced it I thought no way can this engine be holding me back this well and tried the same hill in manual mode and sure enough the engine was revving way up and still could not hold the trucks speed down like it could in cruise mode.    Fuel mileage, that is where a really low sleek type of car can do better at higher speeds, certainly it starts sucking fuel too but a tall pickup is pushing massive amounts of air and also allowing a lot more air under it and the tow mirrors as in elephant ears pushing through the wind  as well. Driving like grandpa is about as good as one can do when driving one of these if trying to get the best fuel economy they can. I bet these trucks would get the best mileage they can if driven on a freeway in Florida if not busy traffic at a sedate speed and that sea level elevation without hills, vastly different then Colorado !.
