The devoted hand-held scan software is a self-contained gadget that plugs into the OBD2 port through cable (ideally lengthy sufficient to achieve from contained in the automotive to the engine bay) and does its job. It has its personal display, buttons, software program and pc chip.

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

Professional suggestions

The nice majority of OBD2 scanners bought right now will work on the good majority of autos constructed for mannequin 12 months 1996 and past.
