My brother recently bought a 2009 Tahoe from a used dealer. While cycling through the DIC/IPC data he noticed the trip counter read a much higher mileage than that of the odometer mileage. The trip reads 186861.1 MI while the odometer says 126942 MI. He verified that the trip was counting at tenths of a mile and after it reached 186861.9 it then rolled over to 186862.xx, so it is counting correctly, as is the odometer. The CarFax that came with the vehicle corresponds with its current mileage. How is it possible for the trip to read higher than the total vehicle mileage, especially an almost 60,000 mile difference? Could the cluster have been replaced at some point and if so, is the mileage stored in the cluster itself or in one of the onboard modules? I attached the photos, hoping the numbers are visible. Thanks y'all!
