My guess one set of wires are switched wrong, look to see which one is working right and look at the wires at the connector. Then look at the other connector to see if the colors match up the same.

Did you call the Dealer and ask them? I'll bet this place will have some, but you might also have to buy a complete rear seat.

Auto or manual trans?

I didn't use JSCAN on mine since I have a Hypertech Programmer and I did it with it, hopefully someone with the JSCAN will chime in.

When you delete the TPMS the light goes out if you use JSCAN.

If it only does it at highway speeds and not under that check the under hood insulation to see if it's getting sucked over the air filter intake and choking it out. It's happened to a couple other Members on here.

I have a Teraflex big brake kit on my JK but it was already on it when I bought it, the pads don't make any noise.

It's just one of the many electrical gremlins these JK's have, the more unnecessary ones you can delete the better.

Everyone that has any issues just use JSCAN to delete the TPMS, that's the best advice I can give.

JSCAN and a OBD Dongle is what most will use.

Only the down stream, but I find it hard that only 1 of them is causing a problem. I can't guarantee this will be your fix, but if the Cats weren't OEM it's a good chance it will fix it. If it was me i'd go ahead and but 2 of them just in case. No issues since installing them either.

If they are aftermarket you may need to do O2 Foolers like I had to do with my High Flow Cats. Read this link I gave you. https://wranglerjkforum.net/posts/465126/

Were the new Cats OEM if not then that would be throwing a code, or is it just one side doing the code. What Brand of O2's were used? Was there a ECM reset done?

It's the best fix for your problem, delete the TPMS and check the tires on a regular schedule. That's just another one of the JK's normal electrical issues.

I'm not really sure it's better for cold starts, but they do say you can get better mileage from using it. I like to add a little Lucas Oil Additive to my oil so that it makes it kinda sticky.
