We have six DD15's / DD13's (2012-2015 models), and three Mercedes (2005 & 2010) in the fleet and all but one of them will connect and give complete data with the new version of DDEC Reports that we got in the spring (can't remember which version right now, but dealer set me up). The one truck that won't give up the info is a 2015. It just shows the message "Data page on this vehicle is disabled". This is also the only truck that Fuel Economy Incentive won't work on. I've enabled it, disabled it, enabled it, changed all the numbers, based on trip/filtered fuel, let a couple dealers have a shot at it, everything I could think of, and FEI won't do anything. Passmart works fine, but FEI won't give me one single mph even when set at 4mpg, and I know it gets better mileage than that. I don't drive the truck, so the speed doesn't bother me. What bothers me is the fact that this one truck just keeps kicking my ##*.
