The tire pressure sensors are 315 Mhz. I would assume this means both the truck and trailer sensors. I don't know if the interface box that mounts on the trailer is just an amplifier or is it a receiver that receives the pressures and then sends the data up the 12 pin cable to the truck's computer. If that box is a receiver then the trailer may use a different frequency all together

I'm curious what you learned? My wheels (bought last Spring for my 2013) with the previous sensors worked for about 1/2 a day then havent worked since.

According to ETIS on my truck:

That's what I figured, otherwise why would they need a 12 pin cable?

Did you retrain your sensors after install? I was able to get the part #'s for the sensors after I went to the website on the computer. The site doesn't work well on my IPhone

Maybe this is better asked in Forescan page but can you bypass the sensors and not have a persistent warning come up on every start?
I hated having to hit reset every time I started my 08 f350 as it read my tires as low.

And then the debate. The TPMS is most important when hauling at or even close to capacity. A 15 lb tire pressure drop (off 80 lbs) can quickly cause a blowout when loaded and in my pea brain the fully loaded situation is the most important to monitor the tire pressure. So by reprogramming with forscan to run around at 55 lbs when mty would mean reprogramming when filling the tires back up to 80 lbs and hooking up the load. Don't know about you guys but everytime we put the camper on and get ready to head out the checklist seems to get longer and longer. Re-programming is another step which could easily be bypassed for the sake of making the launch time. I guess the programming would be that much better if just the phone or the center stack had options to set the alarms. JMHO
