    Iv done this on all of my Prii, the problem is the really only usable info is the 12 V battery level. Of course my multimeters will provide this but it’s good to compare. I only remember turning lights off/on 3 times, ?????

    Nearly all of the ECU-controlled systems on the Prius and Prius Prime have self-diagnostic capabilities, but most require a Toyota Techstream diagnostic system, or at least an OBD II-compatible scan tool, to see anything more than a warning light or message on the multi-information display.

    I’ve posted about some exceptions, like the air conditioning system:

    Air conditioning problem on recirculation (See Post #7) | PriusChat

    and the navigation system:
