TPMS for trailers

[DiverRick]

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!
