It has its personal display screen, buttons, software program and pc chip.

The second kind is a Bluetooth OBD2 scanner, recognized within the commerce as a Bluetooth dongle. This sort is normally a reasonably small, plastic system that plugs into the OBD2 port after which connects to a smartphone or pill through Bluetooth.
