How Do I Read the Check Engine Codes on a Ford F350 6L Diesel Truck?
Ford F350 6L diesel trucks are compliant with the OBD-II (onboard diagnostic) codes mandated by law. The truck’s computer operates an OBD system that diagnoses problems automatically. So, if the check engine light illuminates on the dashboard, you will need to access the computer and read the code. All you need is an OBD-II scanner, available at any auto-parts store.
