    Default 5.9 Cummins Speedometer problem

    I just finished csp file flashed it into truck with no issues. Went on test drive now the speedometer doesn't work and the abs light is on. Has anyone ever ran into this issue.

    Are you positive you flashed the correct file for your truck?Did you change anything else?

    Yes sir os matched both 07 5.9 files. I did not use the stock file from the truck though because it was previously flashed with a smarty.
