ABS , VSC , Repair Attemp

Hi All,

My second post here about this issue. I'm trying to specifically locate the problem. I got the c1343/571 code and attempted to what I believe was a success in bleeding out the air in the RR valve.


I did this three times using tested methods and after I still have the same issue.

So my questions is... What is my next step in troubleshooting?

I still have the same issue / same code... Same wompy brakes.


I'm using this car as a secondary work car so I need to solve this issue ASAP. Any guidance is greatly appreciated.



Thank you

 

Hi P

Hi Patrick,

Thank you for responding to my question. The tested methods were used with the latter from your repsponse. I have been bringing more & more familiar with the tool because I was overcharged at a place for minor wok involving an 02 downstream sensor. Since then I have had a few issues.

Hi Patrick,

Thank you for your response. I was hoping you would respond as I have seen you are super knowledgable over thousands of posts.

As for the tested method described, I have taken advantage of the Mini VCI cable clone with the bundled software. I have had no luck with this issue among other issues separate from the ABS/VSC/ Brake/ C1343 issue.

---- Okay, my progress has come to a halt because I'm not exactly sure where to go from here. Is there any way to test the actuator? I have a chunk of the repair manual from a generous user on this forum so I was able to to bleed the RR valve line.

I believe I successfully bled the RR twice. Both times using the software. (Watching the master cylinder level) The first time the problem didn't come back for about 10 mins or 3 miles of driving. Then I once again bled the RR. This time, the code comes right back after the bleeding process..... Sooooo


My next idea was to bleed the whole system?


Thank you!! All advic & direction is greatly appreciated!!

 

Thank you. I was waiting to see if this would help but wanted a second opinion. I am going to bleed the entire system this weekend using the software.

Also, would it in anyway be possible this problem would be caused by the skid control ECU? is there a way to test the connections with a volt reader? I read somewhere on this forum how a lady had a 2nd gen prius and went through a bunch of diagnosis's before she discovered it was the skid control ecu?

and.... I noticed the other day that this particular prius I purchased was missing the paneling where the drivers feet rest. (such that if you were to look up and almost behind & below while crouching in by the gas pedal to plug in the mini-vci.) I believe this is where the skid control ECU is installed.

So for now I am going to maybe bleed the entire system then the hydraulic system can be ruled out? - Maybe

One more thing --- I saw the actuator pictures from a thread on this forum and it looks pretty intricate.


Thank you!

 

Hi Patrick,

Well I bled the entire system using tech stream software and followed manual instructions - The lights immediately returned. A little frustrated right now. I guess my next step is to try to bleed the system again and if that doesn't work which I presume it wont... I'm going to get my hands on a actuator. Right now I'm searching on ebay and having no trouble finding one. Once I receive the part I will search for a local shop which "specializes in hybrid repair"

Does anyone have an idea of how much a repair like this would cost from toyota? (ballpark figure please) I'm in NYC

 

@Patrick Wong

Does a leaking inverter cooling tank affect the braking system? I'm asking because I noticed a leak as of yesterday. it's coming from the bottom of the car but not near the inverter coolant pump. I'm trying to trace it now. It's a little difficult to find but I think its coming from a cracked hose.

P.s. I'm waiting for a good price on an accumulator to pop up on eBay. It's not my main car so I'm not in a rush to run to a repair shop.
