@JD JeepDumb question, but my 2021 (on order) will be my first Jeep since my 1980's CJ. Does the tire pressure sensor come into play when doing a 5-tire rotation? Meaning it is just an idiot light or specific to the tire? Also, does the spare have a sensor? Sorry if this is a little off-topic, but I thought it was relevant to the discussion.
In regard to your JL's TPMS:
-How does the JL know which tire/rim/wheel is where .....
Well, there are 3 sensors on the chassis that monitor the 4 TPMS Sensors found on the 4 tire (rim) positions.
Info from the 3 chassis sensors is transmitted to the Wireless Control Module. There is no need for a 4th chassis sensor as the computer uses the process of elimination to determine the fourth tire location.
Yes, your JL knows exactly which rim is where, usually within seconds of a tire rotation for example. Yes, It's all done automatically.
The JL, does have a TPMS sensor in the spare, but it is not read by a chassis sensor/ considered by the computer until it is placed in one of the 4 tire positions.
