My brother recently told me that his workshop is in urgent need to get a powerful truck diagnostic tool, which can work with a variety of vehicles, and more important it has good quality and stable work. So I tried to find more useful information through Internet, and finally I found NEXIQ USB Link truck scanner with both good comments and good sales sold at a Chinese online shop.
No cable is needed for vehicle diagnostic using the Nexiq USB Link Nexiq Scanner. The diagnostic base system can access the NEXIQ USB link via Bluetooth or USB.NEXIQ has been set up after well connected with vehicle. The Bluetooth software provides a virtual serial COM port (Bluetooth Serial Port Profile).
Nexiq 125032 USB can be also connected to the application PC by using the supplied USB cable. Windows detects the NEXIQ USB link through Plug and Play, and automatically installs the drivers copied when you installed the diagnostic application. Then NEXIQ completes setup and the diagnostic interface software is ready for use by the diagnostic application.
