This I believe would be "time wasted" without doing diagnostics 1st.

Scanning and diagnostic requirements are very different dependent upon the system that you want to check. The "jumper" FLASH or the ECM/CCM through the DIC are very reliable for some. Short of a quality Tech1/1a or the Snap-on offering everything else is insufficient. A laptop for "run diagnostics" yes but NOT for "controlled devices" in the car.
