2008 Prius Not Starting after Inverter Change

I received a notice from the Toyota Dealership that my Power Inverter on my 2008 Prius needed to be replaced. This would only cost me $6,100 to get done!!! After watching some you tube videos and searching the internet. I thought I could replace it on my own. Bought a replacement Inverter and got it all hooked up to find out that it leaked coolant from one of the screws on the inverter. (Screw on the bottom left if looking at it from the front of the car). I then put my old inverter back into the car figuring I will have to order another one. Well, I get everything back together and the car has power but when I try to start it doesn't turn on. I look to see what I did wrong, and yes I forgot to slide the "orange plug down" I did that and still same issue no start. Read on the forums and everyone says you need a new 12 volt battery. I get that so I tried to jump start it. No luck. The lights all work. The doors unlock, the windshield wipers run. Headlights turn on. The indicator lights on the dash seem to be bright not dim. I used a voltage meter on the 12 volt battery it is says ok. I have jumped this car before when we have had 12 volt battery issues I guess have a charger so I am going to try to charge it tonight and see what happens. I have also ordered an ODB2 Scanner from Amazon that should be here tomorrow as well. Maybe that can give me more details. I keep thinking the orange plug didn't get put in right so have tried that about 20 times (making sure it is pushed down). No luck so far. I also understand that the inverter cover has a plug. I guess I am pretty sure it was connected when I put the cover back on. All the screws lined up and even the guide pin on the upper right. Just wondering if anyone has suggestions. Thank you in advance.

 

Looks like I am getting Codes P0A09 and P0A0D: "DC/DC converter status circuit input low" and "High voltage system interlock circuit high." If anybody can help me interpret what exactly this means, I would be grateful.

As I mentioned before I removed the Power Inverter, and the car was starting fine. The replacement inverter leaked antifreeze, so I ended up putting the old inverter back in. Now, I am getting these codes.

Do you think I might have damaged the inverter? If the recommendation is to replace it with another non-leaking inverter, do you have any suggestions? Thank you

 

Thank you I will work on this tonight and see where this gets me. Thank you for your time and post

 

So I figured out the P0A0D issue. It wasn't the Orange Plug, but I had really messed up putting the Inverter Cover back on. I failed to notice this connection and it didn't turn out well. I was able to get this connected again and the car will now turn on. No more P0A0D Code!

I checked all the other electrical connections and they seemed fine. Maybe I am not understand the P0A09 code, but I am still getting the P0A09 code with the Red Triangle, AMS (!) lights. I assume this means I need a new inverter still? (Maybe I will find one that doesn't leak)

Just wondering if that is how I should proceed with this code or if there is more going on?

 

I replaced the Power Inveter, but I am still getting code P0A09 "DC/DC converter status circuit input low. The car will turn on. Here is a picture.

Any suggestions? I have checked the battery a couple of times and it says good, but as you can see it is showing a battery on the monitor.
