    Hey, happy to find a place with great info like this, so thank you for that.
    My name is Scot, just got a Prius from a young guy that drove it till it died but I got it delivered to my house cheap, so a project is at hand. Took it all apart today to get an appraisal of needed items, I found.
    This thing has no aluminum core in the rear bumper cover, so need that and a new front and rear bumpers, but before that I need the coolant heat storage tank, it has a broken off fitting at the bottom, he got hit from behind and pushed into a car in front of him, the damage is so minor I believe him when he says it was very slow and at a stop light.
    Also the 12 volt battery in the rear is missing the fusible link and the 12 volt battery itself is dead, he told me the battery went bad, because the car has been sitting for a year, till he decided he wasn’t gonna fix it.
    I try testing the hybrid battery by plugging the orange safety block back in, but I get nothing across the two main terminals out. I have the safety pushed in swiveled down and the bail arm pushed down. I hear, on a car this old, if the hybrid battery isn’t exercised daily it dies. Good news, the body of the car looks solid enough no other dents or damage, the interior is nice and fairly clean.
    My questions are, are there Prius specific part sources that are like salvage yard outlets. And do you guys like Electron Automotive ?

    Looks like you're in Nevada If you look around enough you could find somebody willing to give you all that stuff fairly cheap these cars are coming off the road and droves as of late I mean I just bought one the other day for like $600 and it's drivable clean leather interior that type of thing so it's not a parts car I have a parts car sitting here sounds like you might need a good bit of one or something along those lines .

    Ah, hadn’t thought of that, but yeah, maybe a cheap parts car, and get one to run, I’m sure I need the HV and 12 volt batteries though, so that’s gonna cost a bit

    Yes the two batteries will cost a bit now you can get some guys can do these things and turn them around for you for 750 bucks You just have to look around Nevada that's out there near where sema shows and all kinds of events happen. There are shops around there that are all into this electric EV partial EV hybrid vehicle repair It's the new thing so there's always that You just have to shop around you can find private people that actually have equipment know what they're doing bus bars and nuts and all that are relatively not so pricey anymore. One of my guys complains all the time that bus bars and nuts and stuff are not cheap so on and so forth I said well you know you're busy you don't have time to look around. I told him I'd take some of my stuff and throw them in my daughter's rock Tumblr from her kindergarten days with the right abrasive let him spend a little while and they look brand new oh well whatever it takes But yeah you can get parts cars now for near free people just want them out of their yard out of their side yard their kids lost interest whatever You can sometimes get them for free many times lots of parts will be good A lot of times people have replaced bunches of parts on these cars trying to get them to run or do whatever again and then they give up at the last minute right when they're almost finished they just lose it and that's that and if you're good at looking at these things you can tell when that's had all the pumps replaced and so on and so forth and tell the guy I give you $400 it's worth that in just the parts.

    How much did you pay for that PRIUS?
    Sounds like it needs a lot of things..

    Im a mechanic, I custom fabricate Jeeps for extreme rock crawling, it’s a new challenge to fix something I’ve never worked on before, plus I guess I’m a dumb a@@

    I think I have all those parts sitting off right here so they shouldn't be too hard to round up much of anywhere.

    The mechanical stuff on Priusses is fairly easy, other than ultra light weight parts breaking in your hands. The electronics is something else. You'll get it, but it's a steep learning curve and in no way intuitive. Think taking your laptop scuba diving in Hawaii and leaving it to dry overnight on the beach and expecting it to boot right up and log onto your email. ;-)

    One challenge is finding a source of salvage parts. I was in that area for a while and didn’t find a lot of junkyards. As you doubtless know many junkyards today focus on selling parts online. Which sounds fine but shipping adds a lot to cost. In SoCal there are a lot of junkyards, and some salvage places that specialize in Priuses. It’s easy to find HV bats and other parts from low mileage and/or low age wrecks for not too much money.
    I suggest getting a hacked copy of Techstream (the hackers supply a file which makes it “never expire”). Search “mini VCI cable” on eBay.
    You no doubt already have 12 v bat chargers. Also build yourself a “grid charger”. Search on here how to do that for cheap. Basically it uses a high voltage but low power LED driver to recharge the HV bat. Cheap and easy.
    Mighty Max 35Ah bats on Amazon for $85 easily fit into the small area of the 12v bat and easily attach to the Prius bat cables.
    You also likely have a digital multimeter.
    These things all help to keep the electrical systems powered which is essential because the electric motors are necessary to start the engine.
    Good luck with your project.

    And you need a cheap laptop to run Techstream.

    Thanks John, yeah, I’m just using an I pad don’t own a computer and haven’t since I retired 8 years ago. But some good points on the parts, I ordered the CHST on eBay for 85 bucks, after lots of review, I am nervous that a total loss of coolant from the coolant heat storage tank could have damaged the inverter or motor. So my first point of investigation will revolve around getting some coolant in the system and finding out where I stand on that front. The guy i got the car from was confident that all was okay, because the car was shut down right away,but who knows. Once I determine that ( not sure how yet with no battery power ) I will move on to more expensive components. My thought was coolant, then 12 volt battery, try and get the HV battery to have some charge, then cycle the system with the autel obdll scanner to see what codes are logged. Then I’ll do the cometic stuff like the rear crash core and cover ( bumper skin ).

    The CHST is in the engine cooling system, not the inverter cooling loop, so no worries for the inverter.

    You won't get any power out of the HV battery unless the car gets to READY condition, where the main output relays are closed. You should be able to measure voltage on the "battery" side of those relays though.

    Hi Scot, laptops are cheap on Amazon or eBay. Techstream is hands down the best way to read codes. This is an electric/electronic car. The mechanical stuff is easy. The electronics is much harder, and I always need all the help and tools I can get. I wouldn't even try it without having all the things I mentioned at a minimum. Even throwing parts at it, which I'm not averse to doing, usually gets me nowhere. My humble opinion is that a Prius is one of the most complex, complicated cars out there due mostly to the level of electronics required to get the simplest things working. Good luck.

    Point well taken John on the laptop, I’m grateful for the advice and help offered here, I have been reading and buffing up on my knowledge before making too many decisions . I figure small steps, with lots of learning for the win.

    If it was my project first thing would be jumper cables to the 12V battery and see if the computer comes alive. Then you will see the screen and know what condition the battery is in. Regardless of coolant situation the engine or inverter can run for 30 seconds. Weird thing about these cars, the 12V powers the car computers and nothing happens until they boot up.

    What model Autel scantool do you have? Some are capable enough to perform diagnostics on a Gen2 Prius.

    Get a copy of the factory service manual (google can find iit in pdf form, or get a short term subscription to Toyota TIS and download a bunch of stuff)

    I would suggest: 12V power to the car- power on "ignition" (power button x2 but no foot on brake). Scan all systems and see what reports back and what codes. A Gen2 had 14-16 different systems. You want a report that says your tool checked system A,B,C...X,Y,Z and each system did or did not have codes (most cheaper tools will report "no codes found" for systems that they can't talk to).

    If your scantool can't check ALL systems then Techstream is certainly an option. You can also read this thread that reviews several scantool apps and devices.

    You should be able to read battery block voltages from the HV battery ecu. You want to see total pack voltage over 200-205V, with blocks all within 0.3V of each other. I would not be surprised if the HV pack needs work.

    The CHS tank is part of the Internal Combustion Engine cooling system. Either replace the tank (or for testing, "replace" it with a heater hose T). Then pressure test the ICE cooling system for leaks (pull the plugs to look for headgasket seeps into the cylinders).

    Clean the throttle body bore and MAF sensor. Check fuel pump operation. Ideally pump the old fuel out of the tank and refill with fresh.

    Do all that - if things look good, try going "ready" (foot on brake and press power button - might take x2).

    You buy parts from people out of their yards lots of people have these believe it or not in their yards not in HOA neighborhoods in the city mind you but out in the county where a lot of the real people who do things live a lot of them advertised on craigslist in the Facebook marketplace I buy whole cars for five $600 complete usually without dents and that sort of thing complete vehicles You could take the body parts right off and put them on another car in other words sometimes they'll be a dent in the bumper cover front and rear or something similar to that but those are just plastic pieces heat with the heat gun pop it out and let it rip If you're buying everything from eBay sellers online You're about paying retail just beware of that most of these things that are going on online are far from any kind of a reasonable deal generally speaking even salvage yards have caught on they've raised their prices because they know how silly people are.
