Automotive scan tools are actually small computers run by programs like all other computers. Computers themselves, when demythologized, emerge from the fog as remarkably simple devices that think in 1's and 0's. They're not that smart. The true "intelligence" and complexity of any machine always lies with the program within.

When purchasing automotive scan tools and software, evaluate first the frequency with which you either personally or professionally encounter technological and mechanical change, or choose automotive scan tools with software upgrade options that will adapt an existing unit to new industry developments without requiring unit replacement with each advance in technology.
