From previous discussions, it was found that the later 2011's and now the 2012's will go into a relearn mode without any special tools. You do need the relearn tool to reset the sensors after you are in the relearn mode, but it can all be done by the owner according to the 2012 owner's manual. I have copied the section which tells how to enter the relearn mode right from the 2012 owner's manual found on line.medicrxdoc said:Make sure that your DIC has the ability to get to resetting the tire sensors. IIRC thd eary 11s did, but the later ones didn't. The tool still needs the vehicle to be in the "learn" mode.
