This is an update to How to set TPMS to ANY pressure. Special thanks goes to @Indytruckchampion for creating the original thread with the process and to @articsilber323 for figuring out that another device (Autel Maxisys) can do this since FCA removed the ability from the dealers. PLEASE read the common questions below before asking additional questions.

General info:
To fully adjust the TPMS you need the change the psi thresholds and update the RFH (Radio frequency hub).

Factory pressure settings are 65 front & 80 rear with a 20% threshold which means that the warnings (light, sounds & nag screen) will come on at 52 front & 64 rear. If that happens then you will have to air the tires to 65 front and/or 80 rear to make the warnings go away.

The PIN – You must have your PIN to fully adjust the TPMS system and you get it from the Parts dept. The Service dept. will be of absolutely no help, trust me. There are 2 PIN numbers associated with your key and truck. Technically, there's a 3rd one too that's a rolling code (unknown digits) that expires. It is only used if you lose all your keys and it requires a call to Lord FCA to get. I believe this is where some dealers get confused and try to tell you that the 4-digit PIN will expire. I've not heard of anyone saying that theirs expired when they tried to use it. A few members have been charged a fee to get the code. Personally, I find this ridiculous and I’d find another dealer, but I realize some don't have that choice.
PIN #1: 4-digit code (all numbers) that is used to program the key (fobik) to the truck. This is the one you need for this process.
PIN #2: 5-digit code with a letter in front (ex. M0000) that is used to cut a new metal key.

IMO, it’s a good idea to get both codes as soon as you possibly can. Recently, some dealers have refused to give them out. It’s yours and you paid for it when you bought the truck so go get it.

Devices:
Autel MaxiSys -- will adjust the psi settings and update the RFH (Radio frequency hub)
Matco Maxgo & Maxme -- use to adjust the psi settings and update the RFH but now questionable
Launch X431 V+ -- will adjust the psi settings and update the RFH
AutoEnginuity software -- will only adjust the psi settings (also tire sizes & enable fogs w/highs)
Witech (dealer) -- will only update the RFH, IF you can find a dealer that's willing do it
AEV ProCal -- will only adjust the psi settings (tire sizes & other settings)
Snap-on – no one has found that any of their devices can do this

Common questions:
Q: Can the dealer do this?
A: They cannot change the psi thresholds but they have the ability to update the RFH. Whether they or not is questionable.

Q: Is there someone near me that can do this?
A: HERE is a map that shows all known members that have an Autel.

Q: Will this ‘change’ get removed if I get a flash update from the dealer or if I install a delete tune.
A: a BCM flash from the dealer could reset some settings but a tune install will not.

Q: Will this ‘change’ void my warranty.
A: First they have to prove that it caused a problem and how they gonna 'see' it since the Witech can't get to the settings but anything's possible.

Q: What model of Autel MaxiSys can do this?
A: The common model is MS906 but any MaxiSys model should have this ability excluding Dodge software version 7.51 & 7.53. The MaxiDAS $ MaxiTPMS cannot complete this process.

Q: Can the Autel MaxiSys make other adjustments like larger tires or enable fogs w/highs?
A: It’s a very powerful diagnostic device but it cannot make those adjustments.

Q: Where can I find the instructions do make the adjustments?
A: articsilber323 provided these in post #912 in the original thread. Some of the screens have changed with the newer software versions but the process is generally the same.

Please read the last Q&A.

Also, I updated the map to include a phone number and notes. I have home and work addresses for some members on the map. If others would like that or would like to add phone # and/or notes, please send me a PM with that info and I'll gladly add it.

I ran through the revised procedure with 4x4x4door's Autel a few days ago. Worked like a charm! Thanks 4x4x4door

Looking for anyone in Virginia. I am in Richmond.

Thanks!
There's a map in the original post. Send me a PM if no one is close enough and I'll let you know how you can make the change from the comfort of your house.

If you're wanting to do this and don't have anybody with an Autel in your area, send a PM to BPMPVET. He's super easy to work with and after a deposit he will send you his Autel via USPS. I used his Autel and it worked flawlessly on my 15 Cummins. No more low pressure light/screen!!!!!

Just a quick question. Is the 4 digit PIN the same pin you use to unlock the commercial settings in the EVIC? I bought my truck used, so I have to go get it reset anyways, and I want to make sure I get the correct code.

Thanks!
