After a rotation, you usually have to re-learn the sensors. Since I do not have this function in my Jeep, I am not positive but recently on a Ford van I had to do this. It is easy and documented in the owners manual. I imagine Jeep's is not much different. Usually the dealer will do this but if you rotate your own you will have to do it. In reality, it should not be a concern on our Jeeps since the pressure is suppose to be the same in all four tires. On the Ford van, the rears were 5 lbs higher thus throwing the sensors off when I adjusted the tp accordingly.

Caught my curiosity. Checked my build sheet and its part of the connectivity group.

It is posted around that the jeeps just have to be driven to relearn. No dealer or tpms tool required.

We were talking about the AEVPM and it doesn't tell you the individual tire pressure--the jeep ECU does if it's not disabled !

The premium "tire pressure monitoring system" does tell you the individual tire pressures, it shows up in the EVIC.

My Rubicon X does tell individual pressures. I have also switched out my stock wheels / sensors for aftermarket wheels / aftermarket sensors. I paid $20 each for sensors on Amazon. I took the rims / tires / and sensors to the shop and had them mounted and balanced. Brought them home and put them on my Rubi. By the time I backed down the driveway into the road to go for a test spin, the low pressure light had already gone out and all 4 pressures were showing in the EVIC.

Correct, after rotation it may take a few miles but they will correct themselves.

Same goes for a low pressure trigger, sometimes it takes a few miles to stop bugging you.

As others said I believe the EVIC is required to see the pressure, otherwise you only get the warning light if something is wrong.
