whats happening to you is totally different than what is happening to me and a few of us others. I have my tpms disabled through my bully dog GT tuner, so thats not my issue.
Okay, to clarify...
Ok here's my info, 2008 JKU bought new in 2008. Mine is a soft top full door version with manual everything, no alarm or key fob or nothing. I drove it stock till the 36,000 was reached. Swapped wheels and tires but not the tpms sensors, that's when my tpms light came on and every so often while driving I get a chime followed by the tpms light and that red light alternating blinking for a few minutes with multiple chimes and then it goes off for a while. Shutting the rig down does stop the sequence but it will always come back eventually. No codes, and I only get the red light with the tpms system reminding me it's not reading any sensors so I know the red light is solely related to the tpms system on my rig.
Well I suspect I know a whole lot less than many here but I do know this, I swapped the stock 16's for the 17's on my 09 JK, after a while the "tire" light came on and stayed on, no big deal, pressures are at 32 or 33...annoying but not a deal killer.
this week all of a sudden the dash dinging takes over, then I get this LOW TIRE warning AND the RED security light starts flashing. SO, I do what every typical man does, jump out and check the tires. nahh..each hard as a rock. Then I drive away and the alarm goes off as well as the RED light....then it comes back on. Then off, then on, then off , then on...I feel like I'm on Candid Camera...
I put all the pressures up to about 40..the TIRE light stays on even after 10 minutes or miles, but I have not seen the LOW TIRE alarm or RED security light which in my mind are connected at the hip.
So, being the man I am , I ordered the Superchips 3570 FlashCal and will deal with this crazy TPMS system in very short order.
Somehow there is just something fundamentally wrong with driving down the road with 4 good, no, make that GREAT tires ( less than 5k miles) and your vehicle is telling you that you have a flat !
Hello, I am new to this forum. I bought a 2008 2 door Rubicon about 6 months ago, and it is starting to have similar issues.
While driving at 65 to 75 MPH, night time, heater on, the red LED above the temp gauge comes on, and the low tire lamp comes on, and the transmission indicator (PRND below tachometer) gets very bright, for just a few seconds, then all goes back to normal. This happened about 4 times in 15 miles, after the Jeep warmed up.
My Jeep is all stock as far as I can tell. It does have just about all options except leather and heated seats. Has power windows / locks / remote start / alarm / factory 730N radio, automatic trans. and around 63K miles.
I'll try to do some more testing and get more information, but I have to think Jeep / Chrysler / Fiat must know about this by now since so many people are having similar issues.
I tried to video it tonight after it did it 4 times, but of course it did not do it again before I got to my exit.
These experiences echo mine.
If the TPMS is disabled via a tuner, does it truly take it out of the equation? I don't know the canbus interfacing between the modules or the programming, but I'm guessing it just prevents the low pressure light from illuminating by injecting a value in the stream. I doubt it would remove it from the system as that would require the code to be recompiled. Since no one knows WHAT the source of the problem is, I'm not ready to rule out the TPMS.
I just thought I'd add my experiences. If I didn't have the low warning light, the red light would indeed mimic what I've seen posted about the "flicker" and steady on states. Just my .02.
