Inverter replacement on Gen 2 Prius. Is it DIYable?

The problem: I recently bought a used 2005 Prius with over 160k miles on it in July 2022. It didn't give me any problems in my six months of ownership. The previous owner told me he had the hybrid battery "fixed". I think he meant serviced and probably changed some cells. Couple of weeks ago when I started the car a master warning light, check engine light, ((!)), ABS and VSC lit up on my dashboard and the car stopped moving. I didn't drive that day. That week, I tried driving it to a mechanic and on the way there, the lights disappeared. It kept happening as I drove a three of four times after that. The lights would come on when I start the car and would go away eventually if I kept the car running. I took it to a dealer and they found P0A63 code - a bad inverter and quoted me around $1500 for installing a used one. I can buy a used one off eBay for under $300. I'm tempted to do it myself and save $1100 in labor costs. They didn't say anything about the pump.

DIY: My experience is limited to changing struts and sway bar links. I am familiar with the wheel and suspension parts of a car. I also changed the 12v battery myself, but it's a very easy job in my opinion. I am enthusiastic about doing any mechanical work that's doable. I would also like to think that I know when to let the experts handle it. I watched a video and it look straightforward. The electricals scare me though. Is it doable with out a mess up?

 

There is only video I could find and it looked pretty straightforward.

 

That is interesting. Please forgive my ignorance on Dr. Prius. I never heard of it before. Do you have any recommendations for a Bluetooth OBD scanner for an iPhone?

 

I checked with them. My subcodes are 300 and 302. I found this document (doesn't let me post the link) posted by someone on this forum. According to the document I have to open the inverter to test these connectors. If they are faulty, I can just replace the connectors, if not, I have to replace the inverter assembly.

 

I ordered a VeePeak on Amazon. Should be receiving it tomorrow. I will post the images once I scan my car.

 

I got my Veepeak. I could only get the hybrid battery information on Dr. Prius app. Rest of the engine codes weren't that useful. I am attaching the OBD report I got when I took it too the dealership in addition to the hybrid battery health from Dr. Prius app. I didn't find any blown fuses. I think it's the inverter failure.
