I have used the advanced search to find an answer to no avail, so here is my question.

I will be mounting a new winter wheel set next month that includes new sensors. I already know that the sensors/ECU will have to be initialized so that the ECU recognizes the new sensors.
Question; Next spring, when the summer wheel set returns to the car, will the ECU have to be initialized again or will it remember the previously mounted sensors?
2nd Question; Likewise, when the winter wheels are mounted again the following year, but rotated (front to back, back to front) will this mess up the ECU with the need to have the ECU initialized again?
Anybody been there done that?
TIA

 

Yes, you will have to reset it every time you change TPMS's. If I were you, I would not add new TPMS's for your winter tires.

 

Thanks for your quick reply, I'll just have them reset which my local Chrysler dealership does while I wait at no charge. It took them less then 20 minutes the last time it was done. Having said that, I can appreciate your comment about not using the TPMS's for a winter set, however I'm kinda fussy (****) about my cars and expect everything to work as should. As much as the TPMS's can be a nuisance, they do give you a heads up as they did recently with my summer set. Sure enough, I had neglected the tires over the last year and all needed a few pounds added.

 

I got lazy and never calibrated my summer set. Now have the winter set back on and the warning light has turned off for the first time since July.

I intend to do it to summer set when they come back in May. With these low profile tires we can use all the warning that we can get. I've had the light pop on twice at speed. The first time it happened the tire was trailing smoke before I got the car pulled over and stopped.

 

I didn't know your dealer would do the reset for free. In that case I agree have them reset every time.
