I recently replaced my ECM with a Cummins Re-Con unit. the truck runs fine and it seems the problems are cured by the cruise control light is on. Is this something that would be cured by having the unit programmed to the vehicle at the Chrysler dealer?

I had an ECM rebuilt by one of the internet re builder's with the same issue. The light was on but the cruise did not work. does your's? I never found out why because the ECM crapped put several months later. I would think it would be a warranty issue with Cummins or who ever you purchase it from. As far as a re flash curing the issue, i would not know.

A re-flash by a Mopar/Dodge dealer will fix the problem. I had the same issue and was told the same computer goes to so many different models that it needs to be "Flashed" specific to the engine # on the build plate.
