A scan tool with its own screen works on any car without your phone, from a handheld with a small display to an 8 or 10 inch Android tablet. Most connect to the OBD2 port by cable; wireless models add a Bluetooth plug so you can stand at the engine bay while a test runs. Tablets run more service functions than dongles and higher priced ones add ECU coding, but most include only one or two years of free updates.
