I doubt its the mechanic messing around. This is a very well established custom truck shop that primarily works on jeeps. These are the kind of people that brand their reputation, go to SEMA and build their own jeeps from ground up. They built this one (in pic) literally chassis first. Why would they mess around? They literally steered me away from buying certain extra stuff for my jeep because they said it wasnt needed lol. They truly look out for their customers and gave me veryyy good deals that various web stores couldnt match. Jus sayin
TPMS: new wheels and J-SCAN
- Thread starter WestCoastDan
- Start date
For reference, I just looked up the info in the owner’s manual.
No mention of reprogramming, no mention of a reset/learn button under the steering wheel, etc…
But it does state that after inflation, it needs to be driven for 20 minutes to make the light go off.

Thank you for lookin that up.
Well the light definitely didnt go off after the first 100 miles. Im hoping they will finally self learn during the next 100 since they got programmed again for the 2nd time. Im hoping its not some other issue like ECU, but they told me it shouldnt be.
So a quick update. The sensors didnt get picked up. So i bought 5 new mopar sensors off ebay. $60. Had them installed. If these dont work after 50 miles im giving up on this.
Btw the previously installed sensors were aftermarket from some manufacturer in mexico.

I'm about to try this with a second set of wheels I purchased for winter tires. My experience has only been with Ford TPMS and those seem to read/register in about 20 ft. This discussion has me prepared for a different experience... 
Funny thing about that. That was the first place i went two days after getting this jeep jk last july. They told me to hit up the truck specialty shop because i have aftermarket tires (35's) and the jeep dealership doesnt have the right machine to install tpms on said tires.
So its the truck shop that has installed these twice now
I suspect 2 things:
1- The sensors that were installed (yes, both times) could be the wrong frequency for your JK model.
2- The TPMS system within the JK is either disabled or not functioning properly.
The advice to check w/ the dealer was to confirm operation of the system, and that the sensors have an output.
They can scan for & confirm that the sensors have output regardless of tire size.
Instead of playing this game, I simply disabled the system using JSCAN & I'll worry about getting new sensors when I replace these tires.

Bingo. Once they're in the tire, anyone can check functionality. And your OEM dealer isn't being truthful. They do 35s regularly on the new Jeeps and trucks. Factory stock on the new ones.
TPMS monitors are installed in the wheels, not the tires... and if you can put in a valve stem, you can put in the TPMS. Sounds like the Stealership is bending you over.
You would think they wout want my business. They quoted me a new license plate bracket like $200+. I got one on Amazon for $20.
Idk how many pics i can attach.
I bought tpms from this ebay auction:
Ok so i was digging into jscan. Autodetect TPMS was disabled. I enabled it and 2 min later the app says its a no go, disconnect scanner n try again.
The live data shows that it can see the sensors but it's still not working? Attaching screenshots. Any1 got any idea?
Btw the auction they are 433mhz but jscan says 315mhz? Is that old data or did the seller send me the wrong ones? (Seller refunded me already and says new ones are out of stock)

That’s interesting.
This is quite a bit deeper into the program than what I played with.
I may have to take another look to see if there are additional settings that I can check/change in ours.

That was active data. I searched "tire" and selected all pid modules from the search. Most of these i cant seem to edit at all and most dont show up in the separate TPMS module section.
Maybe this is why the local dealership told me it would be over $400 because they had to program the system to see the new sensors…
Im guessing that didnt include the sensors..? Whered u get yours?
If it’s live data, none of it’s editable. Merely showing what can be read from the system.
