There are several threads on this and they are either outdated and/or require very special and VERY expensive equipment. I run my rear tires on my 2500 at 60 psi because I like keeping my teeth in my head and my kidneys unbruised. But I have to deal with the bright yellow light on the dash and having to clear the EVIC every time I start up. Until now......
As mentioned in some other threads, there is simple software you can put on an Android phone/tablet (sorry iPhone!) or a Windows PC for $49. It's called AlfaOBD. And with a $79 OBD connector from Amazon (cheaper ones may work), you can get at just about ANY setting in your truck (or Jeep or any FCA vehicle). To the point that it's practically dangerous how many things you can enable/disable although I haven't seen one person who posted yet that they bricked their CPU. If you pay attention, it's pretty easy to use.
I have a 2018 2500. All I had to do was go to my local dealer's parts counter and ask for my PIN number. You need that to reset the RF hub to make the TPMS reset. Otherwise you can do just about everything else without it. All I had to do is show my registration and license to prove I owned it.
And the other thing I needed is was a firewall bypass harness. Starting with ANY FCA 2018+ year vehicle, you WILL need this to write to the computers. This is because someone figured out it is real easy to hack the 4 G or WiFi in your FCA vehicle and possibly take over your vehicle's computer. So starting in 2018, FCA put in a firewall between the brains and the rest of the vechicle electronics. This cable allows you to talk to everything at once to reprogram things. If your vehicle is 2017 or older, you do NOT need a firewall bypass wire harness. There's a guy in another Ram forum that makes this cable (and others) for $50. I got that and it was a 90 second installation. Link is below on how to order one.
So with my phone, the cable, and the PIN; I reset my TPMS to 60 psi in about 30 seconds. It was a glorious day!!!!
I also enabled daytime running lights by use of my driving lights.
I also made the radio come up with the SRT logo when I start the truck. Why? Because I can!
And I in no way have any affiliation with AlfaOBD, the harness guy, or anything else with this stuff. I'm just a technology nerd searching for a way to reprogram my TPMS light and finally found a way to do it without borrowing somebody's $1000 diagnostic tool.
Your mileage may vary. I just wanted to pass along my success for anyone that is looking to do this. I see TPMS mentioned a lot but no easy solutions, until now. If anyone is interested in a step by step, I provided links below of what you need to purchase and read up on for general instructions. There is a LOT it can do, but my focus was really only on the TPMS stuff.
Many many many thanks to Ghost_RAM and Deereguy in the Ram Forum for planting the seed and sharing the harvest. I apologize and I am not trying to pimp out another forum. I just want to give credit where it is due. The How-To is not mine. I am only graciously paying it forward with the help of trailblazers that plunged into this jungle before me
An Android phone/tablet OR Windows PC to run the AlfaOBD software

or WINDOWS --> AlfaOBD
If you have a 2018+ Ram, you need a security bypass harness: Contact Deereguy in this AlfaOBD thread https://www.ramforum.com/threads/alfaobd.123982/

Your PIN number from the Parts Department at a dealer. You need to have ID when you go. That is FCA's police on giving it out. You own it, so they have to give it to you.
Disclaimer: I am NOT responsible in anyway for what you do with this. It worked for me and one can only assume it will work for you. You are messing with a CPU that costs a LOT of money, so pay attention to what you are doing!!
