Latest software update for MaxxForce 10

We recently purchased a 2012 HR Endeavor and am wondering what is the latest software update for the engine? Currently when I turn the key it reads "REV 1.2". Any information would be appreciated. Thanks.

The "REV 1.2" is not the ECM version number. I think it is the display software. The "Calibration", as Navistar calls it, should be "PBL6XWR3 RPLBAG1". The only way for an owner to find out is to call a dealer and have them look it up OR you can purchase a OnCommand Link device and do it all yourself.

Thanks, Dennis for your help. I checked with the local Navistar service and the software is up to date.
