    Could someone please point me to a previous thread, or provide a run-down for the best code readers for a 2014 Prius v. I have a laptop available if needed, but I need to know my options.

    Mini VCI with Techstream software. Runs best on Windows XP or Windows 7. Runs about $25.

    If you just need to read codes and set some user settings, then Scangauge 2 is also a good choice. With the Scangauge you'll also be able to leave it hooked up to your OBDII port and read real time (real time enough) data with the user selected gauges and x gauges. Runs $150+.

    +1 on mini VCI cable w/ hacked Techstream software. Everything else is junk b/c it can't read all of the ECU on the Prius, limiting you on diagnostics and maintenance capabilities.

    Could go with Drew Technologies Mongoose Pro with Techstream. Cable enables module programming/ECU programming. Four hundred something when I bought it.

    MT2L03 ?

    I use an iPhone app called EngineLink that uses a WiFi dongle hooked to the port. The app was a few buck, but I don't remember. The dongle was ~$25 on Amazon. On the iPhone, the app can be set up, and there are downloadable PIDs for the Prius so you can monitor all the battery module voltages, temps, whatever you want. I originally bought it to turn off the idiotic internal reverse beep. I use it occasionally to keep an eye on the difference between min and max battery module voltage, which I think is a pretty good indicator of battery health.
