TPMS low on 2 tires

[alarmin]

I've been stalking you guys for a while and now it's time for me to jump in. I've got a '15 Ram 2500 6.4 4x4 and while towing home from a long trip my low tire light came on (front right tire). Fearing a flat I pulled off the freeway and checked my tire pressures. They were fine and even a couple of pounds over. Here's where it gets weird. A few minutes later the front left shows low but the EVIC shows my tires psi are a couple pounds over. I'm probably going to disconnect the truck battery and see if it clears (it worked to reset my outside air temp when it got stuck @ 30 degrees). Has anyone else have this problem?

Might be completely wrong, but don't the newer gen Rams have multiple recalls for issues with the onboard computer?

It's more than likely the RF hub. Changed quite a few of them

Now, I feel like big brother knows my truck is modded - in a way I feel violated!

Thanks to all for the replies. I was hoping to avoid going to the dealer since they are scheduling 5 weeks out (WTF). One more question. The TSB stated it's for vehicles built on or before 110514. How do I find out what the build date is on my truck?

The sticker on the driver's side door shows "Date of MFR(Built): 4-15" but it also shows "MDH: 043014". Why would the 2 dates be different???

87 psi?!?!? I didn't know you could do that.

3/4 ton truck calls for 60 front and 80 rear. I was towing and had my tires inflated to that. Add the heat from driving / towing and they register a little higher than cold psi. Now I'm not a tire-ologist but i did sleep at a Holiday Inn Express last night (if you remember the old commercials)

I did some research and my understanding is the "Date of MFR(Built) is the Month and Year, and the "MDH" is the Month Day and Hour. So my truck was built on April 30th 2015 @ 2pm.

The TSB was issued on March 28, 2015? Well that seals it, my dealer sucks. I had a problem like this, took it in, dealer said basically yeah whatever. Inflated my rears to 80psi and deflated my fronts to 55psi (I run them all at 72), drove it around for a bit to let the system reset and called it a day. They sure as hell didn't replace all my TPM sensors though. Guess I'll add this to the list of things I need to mention next time I take it in, right along side the UConnect 5.0 randomly crashing.

I'm sorry to hear about this frustrating dealership experience. Please keep us posted on how it goes the next time you're there, and let me know if there's anything i can do to be of assistance to you!
