    Could somebody give some info on the, Manufacturer Enable Counter, that is in the modules now. If the counter is not at 0, then you will not be able to complete the learning procedures. For example I am dealing with an adaptive cruise control module. Unable to complete the learn procedure because the MEC is at 237. I called TAC and one case was found that involved techline. I called techline and was told that the counter had to be at 0, which I knew that from dealing with a Buick Regal with a cruise problem. So my question is, why is there not a program to make the MEC go to 0? Why is a, Manufacturer Enable Counter, needed and at this time of age why is there no program out there to get rid of it? Any info would be greatly appreciated on this problem.
