Pre-June 2021 TPMS issues.

[Schaft]

I took ownership of my 2021 JTRD, on March 31 of 2021. A few months later, I changed the wheels, to fuel covert and reused my factory 33s. The TPMS system worked flawlessly for at least two years. Then, it began to act up sporadically. After a couple of months of that, it stopped working altogether. Dashboard said “tpms not available,” and - shown at each wheel, on the dash. Every few months, it would work for a few minutes. The last time it worked, was about two months ago and it was for about 10 miles, on the highway. Last week, I put on a new set of icon dynamics recon pro wheels. I coupled them with wild peak AT4’s. I got them from Trail Built Off Road. When I ordered them, they asked for the Vin, so they could verify when it was built, to properly match the TPMS sensors. After installation and over the last week, they still have been detected.
My friend, bought my old tires and wheels, and they were balanced and installed today, at one of the local shops. As soon as his gladiator came off of the lift, and it was started, the TPMS system, recognized the sensors. It was instantaneous. So at this point, I have to assume, it was and still is, an issue with a TPMs antenna or something, on my rig, and not the sensors in the old wheels.
Google said the fuse for the TPMS system, was F94. The fuse was pushed in completely, and when I pulled it, to look at it, I didn’t see a break.
Can any of you well seasoned Jeep owners, venture I guess, as to what it might be,(TPMS antenna)? And if so, let me know what to look for and where. This forum has helped a lot, in the last 1-1/2 years. It’s nice to know the knowledge base is vast, and with many years of experience. Much thanks to all.

Get new TPMS sensors in the tires

Get new TPMS sensors in the tires

He said the sensors that were in his old wheels would periodially work, and when put in his buddy's Jeep, worked fine there too. I doubt it's the sensors.

Well there is a seperate TPMS module that really is rather inexpensive.

Yeah, I think they later combined the TPMS with another part (remote start and keyless entry, maybe), but the system was more complex back then. I think they combined systems because of the chip shortage.

I spent enough money on the Wheels And Tires, another hundred bucks isn’t asking too much, to get the system to work again. Thanks for the great advice.

You are on the right track. It was rolled into the Radio Frequency Hub (RFH)
