Planning to buy a diagnostic scanner? The VXDIAG VCX Nano line of scanners offers some of the best options for diagnostic products. It’s safe to say each and every one of them is a top-quality tool for scanning a vehicle’s onboard systems.
A VXDIAG VCX Nano is basically a PC-to-vehicle interface. It plugs into a vehicle’s OBD2 port and then connects to a PC. The connection can either be wired (via USB cable) or wireless (via Wi-Fi).
Either way, once a connection is established the scanner will be able to run various diagnostic functions like reading DTCs, resetting systems, adaptations, programming, actuation etc.
Note that VXDIAG VCX Nanodevices rely on diagnostic applications to carry out their functions. For example, while the VXDIAG VCX Nano GDS2 and Tech2Win come with GDS2 and Tech2Win software, VXDIAG VCX Nano JLR SDD comes with SDD.
