I've got that message on the dashboard just a week ago after car was parked, not driven for a few days. I've check tire pressure with manual gauge, inflated them a bit, checked spare tire too but the warning message still appears on each start of vehicle.

Any advice on how to clear it? Dashboard tpms info seem accurate.
Is there any user's friendly relearning procedure?

I'm going to try to disconnect the battery, right after the emissions test this week.
No one with this issue yet? Tyres are OK, pressure read ok, it's just stupid EVIC stuck with the warning... Hopefully will clear it with disconnect.

There's no way anything on off-road vehicle can break just by sitting in a garage, even on -20C.

Wow finally after a few months, I'm closer but still very PUZZLED on how to solve this!??
Took a chance today in service on regular oil/filters change, to add to mechanics with TPM/RKE Analyzer to check the message, it returned C0151D as I thought sensors lost their place in WCM/WIN module. And they were too busy doing recall S61, ANOTHER module. So, they say it would took them another 3 hours to check the triggers, sensors, etc.. And these are summer stock wheels with stock sensors, issue appeared with winter wheel set, non-moving, freezing cold... So, I was thinking to manually reprogram sensors IDs into WMC/WIN but... should I do it with winter or summer set? Winter set has also OEM Schrader TPMS and they worked two winters no probs.

And electronics-wise, this is my second US branded car with the same "bugs" in circuits. The previous LaCrosse Buick was doing a show, random full-down windows and trunk opening, sky roof with AI etc

So why the FCA guys need another 3 hours just to reprogram? What's the problem with these modules? Where they are made? How to contact the manufacturer, to suggest some fixes... (I do fix things, especially electric powered)

They are reading OK, all pressure accurate just the error text won't be gone..
These threads helped me to understand:
TPMS Mystery - Jeep Wrangler Forum
TPMS problem - JeepForum.com

I post the results of forcing transmission with sensor IDs to the module.

Bumping my own (still unsolved) thread after a while.

Really guys, is there any diagnostic tool that can precisely say which one of those 3 TPMS transponders mounted in wheel housings (two in the front, and one in the rear), which one is the faulty one??

I have the replacement part for some long time now but I hate even the idea of disassembling all 3 of wheel housing in random order..
