    I will be honest in pointing at manuals does not help as much as it might another because I am mostly self taught and they read like stereo instructions. Read earlier posts and there is a complete diagnostic. I have also found that most field mechanics do follow gut judgement and don't break down to the smallest component.

    I thought my roommate's car had an issue with the inverter but it turns out that seems to have not been the case or there was something else wrong. With my car I was getting a lot of extraneous codes and thought the C1343 was caused by other issues. Turns out it appears to be the reverse.

    Getting C1343 with 571. Was able to figure out how to print out a report with techstream instead of pictures.
    Took pictures of dash and the right rear brakes. The pads look like they may be a little thin but I don't think bad at all. Have pictures of techstream report as well but I think the pdf would be even better.

    I can easily bleed the brakes if that might help. I looked at the brake fluid reservoir and looks full but also a little on the dark side.

    Am I likely to need to replace the master brake cylinder? Sorry I mean the ABS actuator I think? Anything else I should try? Also any fuses I should check?

    I cannot afford new right now because they are like $1000+ unless someone knows a source that is far cheaper? Also are there any videos of replacing the abs actuator and/or anyone has detailed instructions?

    Generally here at this point you're replacing an actuator You can go through the 40 pages or whatever it is of the testing business generally it's all going to lead back to the actuator unless you see brake fluid on your back right rear backing plate pull the drum off see the brake fluid coming out of the line connection or the rubber boots on the end of the wheel cylinder You got nothing. It's going to come back to the actuator. You can buy them used online eBay in the 300 350 range The big places like the salvage yards and Conyers Georgia and some others have enough of these cars where they can send you one right out when it doesn't work Make sure you look at their fine print I've installed several used ones in all the cars are running fine and still working some are 3 years in so more than paid for themselves just in that one repair in the savings because the new one is going to be about $1,400 12 to 14.

    Going to assume actuator as a working hypothesis unless I read something brilliant otherwise.
    My plan is to call a junkyard that seems to have Prius parts and see how much they want.
    Depending on what they want, I will go to eBay.

    I have had brake lines rust out on a 1995 Ranger and a 1993 Jeep where I replaced the line.
    I could put the Prius on a tarp to see if I see any leaking

    I did lay eyes on the part Friday so I at least know where it is.
    How hard is it to install them myself? Any good tutorials you know of?

    Do not replace any more parts until you have done a complete diagnostics for that trouble code.

    Did you get the Toyota service manual for C1343 and look at what triggers that code?

    Have you followed the step by step process to troubleshoot that code?

    Roll the car up on ramps it'll take you a whopping 20 minutes to look down the tray and look at all the brake lines If anything is compromised you seen it before on your Rover I've seen it before on a 93 Corolla right here in the southeast United States. So you know what that looks like and anywhere there's leaking brake fluid it's going to look like power steering fluid shiny oil but it's not it's glycol I understand but you'll see it If there's none of that going on then more than likely looking at your actuator and that's just the long and the short of it I've gotten actuators for 50 bucks at junk yards bought two at one time from a guy claiming to rebuild them I paid him for one and he sent two I used them both and they both worked flawlessly they're still working today can't find the guy on eBay or anything just vanish not even in my history is the funny thing it's weird. Typically on eBay from the junk yards down in the southeast they go for about 300 325 something like that. Realizing that many of these things have been replaced and then the hybrid battery goes bad and the person sends the car to the junkyard this is a real scenario that happens probably almost on a daily basis with these cars so a lot of these actuators if you look carefully some of them are looking brand new probably because they are I've bought a few rolling chassis for $700 or so was recently replaced hybrid batteries and door brake actuators like the receipts in the glove box or you can tell it by looking at the parts like brand new and the rest of the car is not and that sort of thing
