Honestly, the solution is no longer a dedicated scan tool.
Get any Android device that has Bluetooth. I use an old, deactivated cell phone. Cost = $0.00
Get an ELM827 OBDII -> Bluetooth adapter. Cost = $10-$20
Download and install the Torque app from the Google Play store. The free version works perfectly well, or spring the $4.99 for the paid version.
(note: the free version has ads. Or it should. Since your decommissioned cell phone can't download the ads, you'll never see them!)
For <$25.00 you'll have 98% of the capability of any scan tool you'd need.
