    I have a 2005 Prius. This morning the engine would not start. The lights came on for about a minute, then flickered, then went dead. I did not leave the fob in the car overnight or the lights on or the door opened, so I'm not sure if the battery could have drained.

    About 15 minutes before this happened my husand opened the back hatch by opening a door and pressing the "open" button. He did not have his fob and wonders if he somehow triggered a security mechanism that shut the car down?

    What did you do during that minute. Was the car in "ready" mode? Did you drive it? Or something else.

    Maybe the battery was weak and the hatch light or door light on for 15 minutes was enough to finish it. It's hard to know unless we have more information about what happened in the minute prior to going dead.

    Most likely it's a dead 12V battery. When was it last replaced?

    When you say you changed the battery, do you mean the 12v battery or the big hybrid battery?

    You need to get Mini VCI so that you can read any logged DTC.

    While you are waiting to get that, put the 12V battery on a charger to make sure it is fully-charged before you continue troubleshooting.

    Press hard on the brake pedal when you are trying to start the car. I noticed the READY light flickering a few times in your video, so the brake light sensor is probably working OK.

    It is premature for you to be talking about replacing parts like the inverter or the system main relays, lacking any clue about what is actually wrong with your car. That is why you need to retrieve the DTC.

    You can obtain factory service manual info at the Toyota Europe techinfo site, once you know what the DTC are:

    Agreed. You need to get the codes read.
    The car's diagnostic code(s) will help pinpoint the problem.

    The problem is that your interlock switch is not correctly installed.

    Or you might be able to get an entire service plug from a scrap yard or used parts reseller.
    I see used ones on ebay for $20 - $30
    search for: prius battery plug

    Yes

    Of course, the question is why the fuse was blown. It is not easy to make that happen.

    So it is a good idea that you are going to get Mini VCI as you will probably need that to retrieve the DTC again after you install a new fuse and it blows.
