Whatever that means.
All of my tire pressures within the limits I set on JScan and the dash is showing me correct pressures for all the tires and they match my pressure gauge. I manually checked all of them this morning before heading off to work.

So, why is my tire pressure warning light coming on, flashing for about a minute and staying on? Is this just an indication that one of the sensors has gone south? None of the four wheels is flashing on the dash as it does if an individual tire pressure is down.
I getting ready to spring for new tires in the next 30 days or so, so if it's a bad sensor, I'll just ignore it until we get new shoes.
 
What about your spare? If you check your pressures on a schedule why not just disable the TPMS?
 
I just bought a very low mileage (17,500 miles) 2017 Wrangler Unlimited Willys Wheeler. I don’t intend to do any muddying, climbing rocks, off roading with it, just road use and traveling with it. How likely is it that I will have similar problems that many are having with the TIPM, Death Wobble, electrical problems, etc.? Thanks

The TPMS isn't really a problem it can be deleted so that it doesn't work. Death wobble happens mostly when a Jeep is lifted incorrectly or when parts wear out. 4x4 vehicles with front coil spring suspensions are more likely to have death wobble then leaf spring vehicles. Just my opinion the reason the Jeeps have the electrical issues is because they have to much controlled by the TIPM and ECM.
 
Thanks BlackJKU. I’m new to Jeeps, but love mine. I hope that Chrysler/Jeep have been or are working on solutions for the TIPM problem. It seems to be a pretty common problem among Chrysler product owners.

Oh, the TIPM. Whoever came up with that idea should be strapped to a rock and crawled on!

Some mess up, some don't. My wife's Liberty is getting screwy. The locks quit working and now the rear wiper continues on and on and on and on, before it finally stops. Oh, the odometer changes on it's own too..... not the actual mileage your smart-asses! :LOL: I mean, it cycles through all of the options on it's own. I'm not sure it's TIPM related though.

All of that being said.... I LOVE my Wrangler!!!

I think the TIPM issues were mostly in the 2012 range. That said, my daughters 2012 hasn't had any issues, nor has my '16 or my daughter in law's '13. My son's 2008 has the same blasted TPMS issue @Anybodyhome mentioned. When the tires were replaced a couple of years ago, I had a full set of TPMS modules that he took in to have replaced. The replaced two. Problem still exists. Really ticked me off, but my son was intimidated to push it. C'est la vie.

I think the death wobble stock JK's experience are due mostly to inferior ball joints and slightly larger than stock tires - recipe for premature wear.

Same exact problem @Anybodyhome, about a month ago. Haven't carried a spare tire for over 8 months, no issues. I went through the motions though. Checked them all, all within 8 psi. Aired them up to 50 psi, bled them back down to 30-32 psi. Light still flashed for 75 seconds and then stayed steady. Bled them down to low 20s, aired them back up to 30-32. Still got the light.


Disabled TPMS, haven't seen the warning since!
Scheduled for a tire change in the next 6 months, may get all new sensors, may just get standard valves, haven't decided.
 
older post, so i am trying my luck... everytime i sart the Jeep JK 2015 message appears. "CHECK TPM SYSTEM"
similar to above except in my case i replaced all 5 tires, and had new mopar tpms sensors as recommended by the dealer. it should relearn these new sensor after 10 minutes of driving but it was a FAIL!!!! after spending unnecessary $$$ in trouble shooting with no solution. in summary; all 5 sensors have been relearned at my garage, from JSCAN i can tell that all sensors are reading correctly, with 32 psi desired pressure and triggers at 26 psi. however all this being said, every time a start my 2015 JK display showing "CHECK TPM SYSTEM" light stays off... anyone have details on the TPM module(s) or solution to this problem?

I have a 2017 JKU Rubicon with 80k. My son has a 2015 JK with 130k. Both are close to stock and do occasional light off-roading (trail riding). They have been very reliable and mostly trouble free. I think you’ll enjoy your Wrangler.

Do you have metal caps on the stems?

As the OP from back in 2021, I followed BLACKJKU's lead and disabled the system shortly after starting this thread. Got myself a decent quality tire pressure gauge and never looked back.

Same. My heap seems happiest in the 26 - 28 psi range, no lights and better ride.

just couriousity... the error code using my jscan is;
trouble codes reported by:
Front Control
U0127
lost communication with the pressure monitor module
active - Front Control
can this possible be caused by the WCM?
Click to expand...

https://www.obd-codes.com/u0127

This code means that the Tire Pressure Monitoring System (TPMS) module and other control modules on the vehicle are not communicating with each other. The circuit most often used to communicate with is known as Controller Area Network bus communications, or simply put, CAN bus.

Without this CAN bus, control modules cannot exchange information, and your scan tool may not be able to get information from the vehicle, depending on which circuit is affected.The TPMS system receives a radio frequency signal from the tire pressure sensors. These inputs are used to inform the driver when tire pressure is too low by a symbol on the dash and in some cases actual tire pressure readings on the overhead module. This input is also communicated to other modules over the bus communications system

Symptoms of a U0127 engine code may include: TPMS Light On

Causes
Typically the causes for this code to set are:
Open in the CAN bus + circuit
Open in the CAN bus - circuit
Short to power in either CAN bus circuit
Short to ground in either CAN bus circuit
Open power or ground to TPMS module – most common
Rarely - faulty control module

Diagnostic and Repair Procedures
A good starting point is always to check for technical service bulletins (TSB) for your particular vehicle. Your issue may be a known issue with a known fix put out by the manufacturer and can save you time and money during diagnosis.If your scan tool can access fault codes and the only one you retrieve from other modules is the U0127, try to access the TPMS module. If you can access codes from the TPMS module, then the U0127 code is either intermittent or a memory code. If unable to access codes for the TPMS module, then the U0127 code that the other modules are setting is active, and the problem is there now.
