    Open inverter casing and loosen 2 wires .
    Than realise that forget to take out HV battery clip out.
    Than take that out and replace inverter assembly.
    Is that blown any fuse anywhere.

    2008 prius was driving okay ...not perfect.

    After that engine start on.
    P Lock mechanics on.
    MG1 and MG2 performance errors.
    Engine constantly running on high reves .
    Hybrid battery behaviour is strange ...half full than empty.

    Any advise what I can do now to solve the problem.

    To take P lock off had 2 blue wires in front bonnet passenger side fuse box.
    Will add photos later on.
    Thanks

    How many miles of the vehicle, is the HV battery original and how long did it sit unused while under repair?

    Original mileage is 280K.
    It was working good no issue .
    Parked 4 month.

    It was in the Garage and connected multiple wires to jump start, was unable to open boot.
    Mixed wires and polarity was wrong .
    Aux Battery top fuse burn
    And error code in photo turn up.

    Then decided to change inverter.
    But even after change over same errors.
    Then tried to put back and forget to get HV plug out.

    And open inverter.

    Car P jam

    Today again put back other inverter.

    It's back to photo errors but most chances are auxiliary battery was the problem.

    Now decided to change photo 2 computer next to battery.

    Order one and hope this will remove errors on dash and battery will charge auxiliary battery better .
    Loses of lights in dash .
    But working
    Even red triangle
