Vsc, ABS ((!)) lights on with Red triangle

There should be codes that can point you to the right direction of the problem.

 

Pretty much you're going to be looking at replacing your brake accumulator and pump It's right behind your inverter It's very heavy If you're not used to it it's kind of a pain in the nice person to change you'll be removing the inverter setting it aside removing the accumulator pump after undoing all the brake lines so you need to make sure that you have access to a 10 mm flare wrench looks like a circle with a little slot in it this is to undo and tighten the brake line fittings this is a $1,700 retail part If you buy it online through Toyota you should get it for around 1430. Some places are now claiming they can get these remanufactured beware of that and if you do get a receipt and make sure you can get an exchange or return. I've changed a few of these you'll need a capable scanner to operate the valves within this aluminum block of this assembly to make it bleed properly generally speaking.

 

Get techstream. Search eBay for mini VCI cable

 

If you don't have a scan tool that can show you the codes, sure, you can go shopping for a better one and that will be good, but don't let that slow you down getting the codes now. You can get them like this:

Here's a thread that reviews several scantool apps and devices. Some are capable of checking codes and data on all systems of a Gen2 Prius.

That combination of light could be several possible things. I wouldn't go buy any parts until you have read the codes or blinked them as ChapmanF said in his post.

 

Beware of sellers on eBay offering this part and it's derivatives as rebuilt as far as I know that's not a thing so be careful return and exchange no problem. There are a bunch of places down in the area of Buford Georgia that have miles of Prius they advertise online selling steering parts and all kinds of nonsense If you query them and look at their yard pictures you'll see generation 2's that you couldn't walk the length of the aisle or row Yes it's outdoors

You're just window shopping now obviously he won't buy anything until it's time. You'll also note on a lot of the junk yards doing the selling the price will be negotiable I usually can get them for about $250 shipped.

Obviously you don't ever purchase anything until you've done your due diligence to know why where and how you're purchasing. It's good to know what your options are.

 

That's right You could go to LKQ and if they had three generation twos if they were in the car could take all three of them probably get them for $40 a piece or something because LKQ does not care about that nonsense and it has happened to me before at LKQ with other like similar parts but that's a be a tough one to find at the junkyard there are people that go out just to grab these parts to try and pimp them on eBay I swear man you wouldn't believe it people are so crooked it's just incredible

 

No man you have to remove the nine bolts that hold the wiper tray in as your problem You have to undo the 14s that hold the wiper arms on pull them off throw them in the car for the people undo the 3 10s that hole the wiper aluminum arm and motor in throw that in the car now undo all the 10 mm bolts that hold the black metal tray in that the wiper sits in throw that in on top of the car not a really needed part now you can access the bolts at the back of the inverter the lid comes off Don't forget the torx bolt up front That's there to keep the idiots out. Do make sure that you have your orange plug out about now because you don't want to be in 200 plus volts live DC power it's enough to take you away from here. After you do that you can undo all the plugs all the 10 mm silver to orange wire bolts withdraw all those lines undo the 12 mm bolt holding the bracket to the same flat that the ABS actuators on and now you can withdraw the inverter set it up on top of the engine drop it on the ground it's at the junkyard Do whatever you want. And now you can begin taking the actuator at the junkyard you can just cut all the lines and pull the whole mess out of the way nobody cares nobody needs those little lines The car is going to be crushed not too far after you're done so there's no need to be careful with all the little lines and unscrewing all of them just cut them oh well. This should all take you about 45 minutes on each car.

 

Has anybody read the codes to find out what's wrong with the brakes yet?

 

The OP posted trouble codes in a thread that he created to ask a question about Techstream. See this post: https://priuschat.com/index.php?posts/3400719

I think the OP is going down a rabbit hole concerning the brakes.

Why do you think you have a bad abs actuator?

Context from that other thread:

C1259 and C1310 are the brake system's "say, did you notice you have a hybrid code?" codes, so they are just telling you about the P0AA6.

B1421 is just the "I'm the code you're supposed to have when sun isn't shining on the dash sensor" code.

C1241, as already mentioned, is about out-of-range voltage reaching the brake system. C1242 is also about power getting to the brake system; the brake computer is in two redundant copies that watch each other, and you get C1242 when one of them gets power and sees the other hasn't. (There's an INF code to go with it, 87 or 88, telling which one had power and which one didn't.)

B1442 is an HVAC code suggesting an issue with the damper servo that selects between fresh and recirculated air.

Many of these are codes that can be read without any scan tool at all, as described on this page:

Some of the more common codes also have explanations on that page.

If it were my car, I think I would run down the power-to-brake-system issues before condemning expensive, tedious-to-replace brake system parts.
