    Hi guys, I'm new here on behalf of my dad. His 2004 Prius start despite the auxiliary battery being fully charged. No lights come up on the dash, except for the door ajar light and the blinkers when the car is locked with the key fob. Can anyone think of any possible explanations? Perhaps a solution as well? Also, we cannot scan any codes because the car doesn't power on at all.

    It can be quite a few things. I would start by pulling the large fuses, located under the hood. I am not familiar with what each one does, but at this point, it would be a starting point.

    1. When was the last time the car worked correctly?
    2. What happened to the car between #1 and now?

    I'd ask Patricks two questions and add a third.

    How do you know the Auxiliary Battery is fully charged?
