2010 Prius Brake, ABS, Traction Control Lights On and Off

Do you have the paperwork from the dealership showing the codes they got from the scan?

Did you pay for this scan?

 

They are typically indicative of just about any of the hundred or so types of trouble that can be detected by the brake system computer. It sets trouble codes that can be read to find out what it's going on about.

 

For that kinda money you might as well buy another 2010 and then you can have a parts car.

While it certainly could be the actuator, I would be skeptical.

Any work been done around the wheels lately? I had the exact symptoms from just a loose connection to a wheel speed sensor. Seems like that'd be more likely something that would come an go as opposed to a "totally dead" actuator.

 

I would hold off on the struts until you figure out what the major problem is. I believe there's a brake warranty for the 2010. I can't remember what it covered but my 2010 had the work done for free. Maybe you can ask them the brake related TSBs and extended warranties for the brake system, maybe it'll cover your issue (or the symptoms)

 

its an easy diy that's posted around here somewhere. I thought there was some warranty extension offered. I just got one off ebay for 100 bucks and stuck it on. Been driving it error free since.

Oh yea, the dealer is trying to clean your clock. They tend to do that when you go there.

 

Great solution, if that's the problem you're having.

 

How many miles are on the car?

 

In the grand scheme of things, all those separate repairs are not terrible in cost,
aside from the fuel system cleaning (scam) but a bit on the hefty side.

But the underlining issue is still not supported without codes.

They cannot guarantee the problem will be fixed, so then what happens?
Move to the next costly repair? and then repeat?

It would be really helpful to know the codes.

 

^ Yeah.

All of the extras too, seem priced to the max: $70 for the plugs, plus $230 labour, to install them? I know the wipers and cowl have to come off, but pros that do this all the time do it in 20 minutes tops.

He notes that the level in the reservoir could give a clue.

Many other threads including that one, owners are saying that adding a bit more fluid actually removes the lights from the dash,
might be something to look deeper into?

 

your not going to get through this issue by adding brake fluid. They mailed out a recall for brake actuators for the 2010. just read it and if you had the problem before nov 30 2019 you would have been covered. Now your 50k miles over the limit. That has to just bite. Time to dump it, get used parts and have someone fix it if you cant but you better stay away from the dealer, he will try to take all your money as you have already seen Best of luck with it.

 

How about posting a picture of what you changed. Not messing with you just want to make sure we are on the same page. The actuator is not the accumulator on the 2010. its near but not there. easy to find with the actuator removed. as far as the tech stream crapping out, yep that's what it does. Manual bleed the front like any car. tech stream the back, very easy. Don't let the reservoir run low or you get to start over. Where in Texas are you?
