No you do not want to buy the h a y n e s manual they're no longer what they were back in the '70s and '80s they used to be published out of the UK I think by a sparkford publishing or something like that I think somebody bought them up and turn them into light reading material what you looking for here is excerpts from the factory three book Toyota manual set and this well Chapman should be able to tell you pretty quick I think he mentioned it before there's like 16 pages for just this trouble so there's a lot you could be reading problem is everybody wants to charge you to read it and didn't used to be like this but everything now's behind the paywall there are some people running around with PDF copies of the real factory three book manual set some people hear sometime will post a link and then you can go read the 16 pages of serious stuff and there's no mistakes they go through it pretty pretty heavy duty-like and I guess my early inverter that purple wire is a different color I have a look to see what it's supposed to be or I don't know position 5 from position 8 in the plug Don't really care. Seems to me like the code is telling you that the DC the DC converter which converts the 200 and some odd volts down to the 13.8 to 14.5 is not sufficient whether the IC circuit or whatever kind of circuit is is gone bad that can't make that voltage so the output is low I think that's what it said in your original code in the text not the numbers so I guess you could get lucky in a wire might be melted bad something seems to me though where the wires are going is not really a very clear path for a lot of melting and hullabaloo with the wires but hey anything is possible in this world so I guess we will see. But I think most of the times that I've read about the DC to DC converter for the 12 volt battery charging usually people are opening up that glued gold plate on the bottom of the inverter and they're changing out that circuitry that's in there because it's non-functioning I don't think it normally seems to be the wiring but it's been ate up by an animal or some such type of thing. There have been people here before not that it matters that wound up changing those internals or they just drop on another inverter The generation twos are pretty stout in the inverter end of it they're nicer than the ones in the generation 3 I think but that doesn't really matter out of the cars we've had here nothing is ever pointed because we need to do anything with that silver top inverter everything else has happened except the blown engine but the inverter only got to move it out of the way to work on the brakes and put it right back not saying that it can happen but these have a very low rate seemingly of failure and people with the generation twos aren't in such a big hurry to change it like some over in the generation 3 they'll slap these things off and on as fast as you can undo the wiring of course there are some recalls for those.

OP TL;DR Summarized below

No, you do not want to buy the Haynes manual. They're no longer what they were back in the '70s and '80s. They used to be published out of the UK, I think by Sparkford Publishing or something like that. I think somebody bought them up and turned them into light reading material.

It seems like you are talking about a specific technical issue with a car. The main points I gathered are that you are looking for specific excerpts from a Toyota manual set, particularly about the DC to DC converter for the 12-volt battery charging. You mentioned that it's challenging to find the information you need without having to pay for it and that some people share PDF copies of the factory manual set online. Additionally, you discussed the differences in the inverter between generation two and generation three cars and how some owners are reluctant to change it due to a low failure rate.

I have the actual Toyota technical manual for a 2002 Prius for the 2003. It is in two volumes.
I was unable to find a paper copy for a 2008 or so.

Tombukt2 · Jun 18, 2024

The 2008 and 9 I believe are the last of the paper manuals but I'm not positive of that I can go down and look in the manual room at my Toyota place now it's all on the computer I believe 2010 forward it's all PDF read it on a screen basis The 2006 to 2009 each of those years I believe is a three manual set very similar to my '85 Supra which is a two big green manual set The books are like thick as the Bible two of them for the Supra Three of them for the Prius I remember when they came out in '04 I think it was one of the first three manual sets in Toyodadom at the time We talked about it in the shop quite a bit so there's always that If you look on eBay you will see the three manual set in paper for $300 $288 somewhere in there. They are around and available I'm supposed to having a set on its way to me here at some point that's another whole bunch of business.

I think Toyota's last year for paper manuals was 2011, maybe 2010. They're online now.

Ways to access them are described on this page:

Toyota Service Information and Where To Find It | PriusChat

Going straight to Toyota's online site involves a nominal fee, is it $25 these days?

Back in the days I bought paper manuals for my cars, $25 would have been unimaginably cheap.

But there are also other options besides going to Toyota's online site, and some of them are free, like if your local public library has an arrangement. Clearly, some of those options depend on where you live.

Elektroingenieur wrote most of what's on that wiki page, and made a real effort to describe all the ways you could get access, including the free ones. If you haven't taken the time to read what he wrote there, you might be making things harder.

That was a very interesting skim. I guess good general information I guess I'm not seriously worried about copyright infringement on technical publications of items that are nearing 20 years old seriously I would love for somebody to bring me a lawsuit for copying publications of a technical manual for my personal use here at my house I would truly will welcome that that would be quite hysterical actually anyhow.

Have a few questions - I was watching a video on how to remove the inverter.
1. This is the one I watched:

Anyone have an alternate suggestions. I don't like his style and would like to watched some others if I have options.
2. He drained the inverter cooling pump. Instead of just letting it drip all over the place, why not just put a tube on it and drain it to a jug? Anyone know the width of the pipe to put a tube over it.
3. Assuming I drain the inverter in that manner, can I reuse the fluid? If not, what should I order?

Just use the the inverter coolant drain on the transaxle.

Replaced the inverter and I think I was completely wrong. The P0A09 is gone but I think it is the C1343 that was causing the problem. Getting the VSC and ABS lights. With sub code 571. I took pictures. I will look into previous discussion of the code to see what I can figure out before posting a new thread.

I am curious about something. When I pulled the tray to get to the battery, it was green instead of silver. Does that mean it is a replacement battery or did Toyota paint some batteries green?
