Tire Size Calibration, Shift Points and Tire Pressure Adjust(warnings/setpoints)

The owners manual states that it's standard on the small 5" screen and "if equipped" for the 8" and 12" screens. Makes total sense :rolleyes:

yes that is odd. I have the 8.4 but mine lists selectable fill alert as standard equipment.

Yes, not listed on my window sticker. I wonder if anyone with the 12" screen has it. Thank you Jadmt for the assist!!

There is a TSB for this feature not working properly on our trucks. I also found another TSB on the Jeep forum since many of them were complaining about it missing. I will drop by the dealer when I have time to see if they can flash the feature in.

You have to delete the old presets. Try that. There is a button to access the presets

Have done this multiple times. Will go out of app and back in and it’s saved as my new thresholds but still shows low pressure indicator on gauge. Then if I turn truck off and back on it randomly resets back to 65psi all around in the ATF. It makes no sense. I swear it worked fine for like a week straight as well then suddenly this.

There must have been an over the air update. My tire fill assist was de-selected and Greyed out. I re-enabled it and it was set to 65.

I hate to say it, but hallelujah! At least I know I’m not going crazy. All I’ve heard on the forum is how this works and I can’t wrap my head around why it isn’t. I too think something changed. Let’s you adjust thresholds still but not lower than the 65psi minimum.

I was able to put mine back down to 45 and save it

I think mine may have had the same issue. I didn't really give it much of a chance though, as I updated mine through AlfaOBD a day or two later.
 
I need to permanently fix mine with my procal snap but I haven’t had a tpms warning yet so I haven’t bothered

Got a procal snap as well. Waiting for it to arrive.

I don't even have the TFA as an option on my truck. Not listed in any of my Uconnect settings. According to the manual it's an "if equipped" option. What option on the truck gives you TFA? My truck is fully loaded. Maybe power wagons don't get it?? @RamCares

Hi Anthony, we would be happy to confirm whether your truck is equipped with this option - feel free to send over a private message with your VIN. Thank you!

When you guys find TSB, particularly those that are otherwise difficult to find, please also make a brief post in the Problems/TSB forum. There is a sticky thread there to post JUST the TSB info. Several members requested this section so it would be nice to see it utilized more. TIA.

I found this at the AEV website. "Please note: A visit to your local Ram Dealership and use of the WiTech diagnostic tool is required to complete this procedure. Although your TPMS screen will show the new values, it will not “take” and stop blinking until your dealership completes the process." Is this true?

That is for 2013-2017 Rams, because the rf hub needs to be reset for the new pressures to take. This is not the case for 2019+ HDs.
