I currently haven't seen any updated TSB's on this issue nor any other types of documentation. For the most part getting an updated PDIM module in a 2010 goes mostly based off of what a dealer wants to do for you. Currently the most updated PDIM is for the 2011 and would normally not be installed in the 2010's. The best thing you can do for now is check to see if your dealer will install the newest PDIM module. Hopefully I get some documentation soon.
