Posted a question under SPN3241 and got a lot of looks but no answers. Weeks of scanning the net and downloading several Cummins and Freightliner helps I now know what I am probably looking at. It is a 2010 Freightliner step van on a M55 chassis. The aftertreatment seems to be different than what is found on the pickups and motorhomes probably because it is designed for stop and go city usage and the information on it seems to be a well kept secret. I need a scan tool that will give me live data on the aftertreatment temperature sensors. My carsoft gives me some live data but not what I need. I don't plan on doing this for a living so don't need the Cadillac version, Chevrolet will work fine as long as it gives me the data I need. Suggestions?

Thanks, Dwight
