the short answer is- when you go thru the DIC menu items- one of them will be to relearn the pressure monitors.
youll then have to let air out of each tire to activate the sensor (or put air in).
The tire that is to be relearned-- the corner lamp will turn on indicating which tire has to be relearned.
I brought it to my local garage to diagnose a recently developed noise that I thought was coming from my wheels or brakes. They've told me the problem is with the transfer case but had nothing more specific. Since I'm still covered by the PTW, my next stop is to the dealer.
