TPMS Reset with no dealer visit

[J VanSteenwyk]

Today I was able to reset my TPMS minus a trip to the dealer for the illusive PIN. The breakdown is as follows;
Purchased an OBDLink MX+ for $80. It was the most expensive component but I have also used it to get CEL codes and reset the CEL on other vehicles so it is well worth it to me.
The second component was AlfaODB for $49 on my Android phone. In the drop down menus it says it is only applicable for vehicles through 2017 but it will connect and work on a 2018 Ram as I have just verified.
Third was an AEV Security Module Bypass cable for $25.
The fourth was the Chrysler PIN Puller app on my phone. For $14 this app will display the Radio Frequency Hub PIN that is required to finalize the TPMS reset. After the dealer gave me the run around about the PIN I decided that $14 was easy.

I now have my 2500 set to 55psi front and 50psi rear with no TPMS light or dings accompanied with the corresponding display every time a I start my truck.

That's strange, my dealer gave me my pin no problem....he just asked why I wanted it.

I called the only Ram dealer in my area and was told that whatever computer program they use was down and they couldn't give me the code.

Update... This morning the dealer called me and gave it to me over the phone. I am just impatient when it comes to accessing information that I am paying for already. YMMV.

J Vansteenwyk,, I recently obtained a OBD Link MX and the alfa obd program. I obtained the PC version and still trying to figure it out. Why did you need the Security module bypass cable? So far I have not discovered the method to alter the low tire pressure warning or turn it off. I do know that my low pressure warning for my 2018 2500 4x is about 45 as that is about where it shut off when I lowered my tire pressure for unloaded driving. From what I have read I have everything needed to effect the change, but so far have not found the area in the program to make that change. I even went to Discount tire where the used there tool to read the serial numbers of each of my tire sensors as I was told that would be needed also. Any tips to make the change would be greatly appreciated.

Apologies for the delay in response. I work overseas and this COVID garbage extended my stay. You need the bypass cable to work around the security built into the computer. In the AlfaOBD app you need to access the menu for a configuration change under the body computer section. There you can change the TPMS threshold. You then need to use your RFH PIN to make the computer accept the change. I hope this helped. If you need more guidance I will gladly assist further.

There are several other forums that have step by step instructions. One thing for sure, especially if you are not familiar is to perform the configuration backup FIRST. FCA no longer keeps the backup configuration on the mainframe. If you screw it up it requires an FCA technical advisor with the engineering software. And they are not going to do it for free.
