This scanner really saves money and time because it works. It's just that the basic diagnosis and repair of trucks in a car service is already more than the price of this scanner. You literally plug it into the OBD port, start the engine and select the menu to run the diagnostics. This is for diesel trucks and when used to diagnose trucks in the menu you need to select "Diesel OBD". When performing vehicle diagnostics, you must select the "OBDII" menu. Finally, depending on the model of your truck, there may or may not be special features. As this is such a broad area to cover I suggest you contact the dealer with your VIN or truck model who will tell you exactly which scanner model is best for your situation. For example, it does not perform forced regeneration or oil cleaning, but performs some other special functions. This model is a bit limited compared to the F506 Pro scanner, but it's also cheaper.
