Jeep App Tire Pressure Monitor System Failure ? ( False Flag ? )

[Ayrilik]

So, I just got my 2020 Gladiator Not long ago from my local dealership, But i finally had gotten around to getting the jeep app connected to the jeep its self after a few days after buying the vehicle. I was slapped with a Tire pressure Monitor System failure " Please see your local dealership " Notification on the app. Some things that I do want to note:

* I am under the suspicion that the previous owner, Did indeed kit out the Jeep. Due to some previous Finds " Cheap Made in China Knockoff Dampener was installed ( Replaced it immediately ) " - Due to the slightest Signs of DW
Drag bar was not torqued to spec and a few other things that where immediately fixed.

* The app does read out that PSI is in the vehicle. and reads it out daily accurately: ( I cannot find TPMS Within the jeep dash or on the radio Uconnect console )

I want to assume that it is possible that the previous owner maybe used a tool or bypass to disable these systems before trade in and the TPMS is actually not damaged or failing in anyway then other than disabled ?


I am planning to pick up a ECRI tool very soon to check these settings, And also re-calibrate my Speedometer, Due to the jeep previously owned and the speedo being off about 5-6 MPH under of what im actually going. maybe this tool can help reenable any disabled systems ? Insight would be greatly appreciated.

If your 2020 is like 2021, you can cycle through the dash display using the steering wheel controls on the left. you can use the up/down button to cycle through categories, right/left buttons to cycle through the screens for each category. One of the categories will have information from the TPMS. The TPMS info is not real time, rather it updates periodically as you drive..

I have been through this menu for a while now, Looked through and through for it, And still have not seen anything TPMS related on my dash display, It literally does not exist I looked through all of its sub menus too, I will go through it again in a few moments and see if i might have overlooked a sub menu. And update in a few.

Previous owner may have changed the TPMS thresholds or disabled TPMS using a Tazer, ECRI or other device. I use ECRI, and it's not a "live" setting, which means that the setting will remain when the device is removed.

Thank you, I will look into this I am currently waiting on my Ecri to get in the mail right now, To my understanding how it functions is it basically reprograms. the Dash. I had noticed a few things off a few days after i had bought my Gladiator. Ill check once i jack it in and see if any settings had been disabled or tampered with that are not by default. You would think the dealership would have reverted these settings to stock.

Also following up on the TPMS on the controls, for the steering wheel menu. Not even the slightest indication that TPMS is even on the Gladiator. So i want to speculate Previous owner indeed did Disable it out right entirely. hence why im getting TPMS System failure on my jeep app as a alert.

Ill follow up once my Ecri comes in the mail hopefully its just as simple as that.

Dealership wanted to charge me a 299 Diagnosis fee just to see whats wrong......

Even if the previous owner disabled the TPMS, you will still see the dash display. It won't show any psi rating for the four tires, that information will be blank.

It will be in the settings where your oil pressure, transmission temp, voltage display is. There is a left right arrow giving your 8 different screens. You need to toggle left or right, not up/down

There is a selectable PID to remove the TPMS menu from the Cluster. I did it on my 2020 using Jscan

So Went back to my Gladiator to get my Rotation and tire balancing done today. I came to realize that their is no TPMS Light All other lights came on but TPMS Via push start (ACC / RUN) Does this further indicate that the previous owner might have out right disabled the Feature out right ?

Not a single display of lights came to show at all. I should probably make a video clip of this. And post it here next time i go out. It might help a bit more diagnosing this. I also have went through every single possible menu i spent a full on hour browsing it. And still could not find it. I'm with @Hootbro On this, here im gonna check with ECRI and check to see if this setting was reprogrammed to out right fully disable. TPMS entirely, I was also thinking to check to see if their is some fuse ? Maybe that fuse is bad ? Just trying to rule out all possibilities here.

All I know is for sure, is seeing from the previous owner, They had kitted the jeep out, Replaced the dampener for a cheap Made in china one before trade in, Most likely had bigger wheels on it causing the speedometer being uncalibrated, I am hopefully banking that they used some tool re-calibrate the speedometer, And most likely disabled TPMS due to them getting TPMS Errors due to the tire size change. We will find out hopefully tomorrow once my package is delivered not much else i can do now since browsing the menus is not giving me results. I will post updates once it comes in.

So posting a update on this, Since i said i would do a follow up !

* The previous owner did indeed toggle the TPMS settings off along with various other things*
I also did re-calibrate my tire size as well. It seems they had much larger tires on then what i had on as stock.

I do have one question though.... TPMS Threshhold should be at 25% of what my max fill is so it would be around 29? or I could just leave it at 36 ? Id think dropping it down within legal range of 25% of max fill would trigger it right ?

Also with that being said thank you everyone for your input and help on this topic ! Have a great new years !
