Thanks, I just saved $1,800 in labor just following along with what you did. Bought an inexpensive Foxwell NT630 Elite ($150) to do the brake bleed and calibration.

Thanks for the shout-out. It was a pleasure to help you out, and help the channel. Great video, that covered alot of the great points. As for Toyota, there is currently a warranty extension on the booster and accumulator on 3rd Gen Priuses and similar year Prius V, but it has to be within a certain VIN range, within a certain age, and within a certain mileage. I'm doubtful it will expand to a full recall, but only time will tell on that. The two 10mm nuts on the pump/accumulator are always a fight, but a good, small magnet is a necessity. You will invent new 4-letter words.

Got version 16.00.020 and the bleeding procedure and linear valve offset learning ran through with no problems.

hi, thanks for this video. i have Auris 2013 hybrid that seems i have the same ABS assembly and booster pump. i have a problem for very long time. a noise appear only when i depress the brake pedal only after light press. for example: when coming slowly to full stop at trafic light the brake is fine. when i get green traffic light i leave the brake pedal and i hear noise and small vibration from the booster area. if youll ask me to describe the noise i would say - low pitch farting noise (i'm very sorry for that but its the closest noise i can describe to what i actually have) it will not happen when im pressing lighter on the brake pedal or harder on the brake pedal, only there is a sweet spot which it will do that. the noise increase when i'm down hill (the angle of the car), but also when the car is fully stopped in parking it will still do that, only when i leave the brake pedal. the electric booster pump working perfect with the regular noise. the car brakes perfect with the brake assist, all brake system works good exept this noise. i'v been at the dealership, thay heard the noise, scanned for errors but there wasn't any. thay said maybe air in the system (thay bleed it few years ago but still i have this noise). i'm looking for solution maybe to grease something or apply some lubricant to something to fix this noise? maybe around this brake pedal lock pin? to replace the booster assembly to a new one it will cost here half the price of this car. would it be better if i'll record a video of this problem? Sorry for my english, doing my best.

@@44liwi I believe that the extended warranty was for 10 years/ 150,000 miles and the last model year under that warranty was 2012, which my car was. There might have been calendar date limit also, so it could have expired. We got in just under the wire, I guess. The hybrid battery went bad in December and the brakes went out in January. We liked the loaner Prius Prime so much that we traded in the 2012 on a 2022. We had to wait a few weeks for the new car to come in because of all the shortages. Most all new Toyotas are pre-sold but, depending on the pecking order, if they are getting more than one, you might be able to get the one you want or wait for the next shipment. I found out about the extended warranty online and then found it on the Toyota website. Toyota is famous for their secret warranties and you have to know what to ask for. If you have been a new Toyota repeat customer, you might be able to contact the area field manager and get something done.

I took my 2013 Toyota Prius type 2 in for this. I was told that when I took it in I can get it diagnosed for about 300 or I can just get the break booster recalled. And me being the typical Prius user I said just do the recall. When I got my receipt it says I received a software update but no claims on the receipt of a replacemen. The car ran fine for 2 days as I’m a Uber driver I drive a lot. I was under 150k miles the first time. But after those 2 days the problem came back. Now I have just one code appear. C1391. And now I’m watching this video to replace the break booster and actuator for myself. But I need that amazing code reader and to learn how to purge the break line. Which is different than a food f150 😂 The things we learn and go thru to save thousands of dollars…😅 I got screwed over. Hopefully this message of mine is someone else’s warning to make sure the item is replaced before taking back a car that appears to be running fine to later have a break booster/actuator that turns on and off that doesn’t always work efficiently. And hopefully someone has some advice for me to still get it fixed before I decide to do the job myself.

[@automatedelectronics6062]

@@leonardofranco5098 A "code reader" will NOT fix your car! A bi-directional scanner is necessary. Expect to spend $1,000's for one. My Snap-on diagnostic scanner cost me $14K in 2016. Then there is the troubleshooting software which a subscription costs several $100. every 6 months. On top of that, you have to buy access to the repair manual. If the job wasn't completed, take it back, they are obligated to complete the repair, especially if it was a safety recall like this one. You might have received a letter from Toyota if the car needed an emission or safety update. But because this was one of Toyota's "secret" warranties, it is basically the owner's responsibility to know about it. Toyota had one of their "secret" warranties with exhaust manifolds cracking on the 20R engines. I had replaced several of these manifolds at my shop. When the manifold cracked on my 1976 Toyota Celica, I had found out about the "secret" warranty, took my car in and they replaced my entire exhaust system from updated exhaust manifold to exhaust outlet tip(including new hangers). A customer of mine with a first generation Camry had his automatic transaxle go bad. The Toyota dealer was happy to repair it for $3600.(an astronomical for the mid 1980's). I told him about the "secret" Toyota warranty, but he didn't want to take it back to the dealer. I repaired it for him at a fraction of the cost Toyota had charged him and he was happy. The correct factory warranty repair is to replace the entire brake unit. One look under the hood would be evident if the brake unit was replaced. They don't have to record it on a workorder. It is an internal repair sent to Toyota. A programming update is standard procedure if there is an update affecting car emissions. The replacement units are on perennially on backorder and they usually keep the car for days. Toyota provides a loaner car while your car is in for an extended stay. Don't attempt to repair it yourself!

My Update 10-2022 2010 Prius This happened to me about 3 months ago. I have been driving with lights on and my MPG has dropped significantly Just got the car back from Toyota dealer. They did the software update recall and reset the lights. I did not replace booster or accumulator ($3068) I noticed on the way home that my brakes regen was working again. about 45 MPG Started the car later and the lights came back on and brake regen was not working. Cleared the lights this AM and drove about 15 minutes and regen was working (I have a scanner that will do this) So apparently the computer triggers the lights and shuts down the regen. I will be leaving on a 900 mile trip in the morning mostly fwy. My thinking is that I don't use my brakes on the highway much so my millage should be maybe a little less than normal. (I'll let you know) I want to see if the lights are triggered by a restart of the car or a certain mileage or maybe a number of brake depression (anybody here know?) It looks like I will need to do this eventually but I need to go on this trip tomorrow so I guess well see what happens. BTW. The engine brake (B on the shifter) will still work and regen even with the lights on I hope this helps someone, Might be my last Toyota.

If you have a light on with no code, the only thing I can think of is the brake fluid being low. Check your level. If it is good, make sure you are using a high quality scan tool and scan every system in the car. I hope this helps!

[@Avesuccess]

MrB thank you for responding so quickly I really appreciate that. I never have an engine light on with the code C 1191. Right now my engine light is on with a misfiring on cylinder number one. I believe it could be My head gasket is leaking because I was losing some coolant until I poured in the quick-fix solution. My brake fluid is not leaking at all. but I have all the symptoms related to code C 1191. I also change my hybrid battery about nine months ago with the refurbished and that solved my problem of the car shutting down while driving on the freeway because I believe it’s a defense mechanism when the battery gets too hot. And I have a permanent code A080. I was told it would go away after driving the Prius 500 mile it’s been over 10,000 and now I am stuck can’t renew my registration. on top of that, I just had my catalytic converter stolen in front of my house in a nice neighborhood over 40 days ago.

Normally the booster unit and the pump are replaced together because one can cause failure of the other.
