    I have a 2015 Prius. Just came back from a 6 day vacation and when I tried starting it, the screen was giving me a hybrid system check with all the other lights on as well and could not put it in gear. The 12v is fine and I did the usual things like disconnecting both batteries for 30min and it still comes on, anyone have any suggestions?

    Suggestion: run a system diagnostic and attach the identified error codes to the topic.

    How’d you determine that? How old is it?

    The 12v is fine as I replaced it about a year ago and reads 12.8v the error code is P2118 and I've tried cleaning the throttle body and disconnected the main power for 30min and checked all fuses, still the same
