Brake actuator replacement - bleed

I originally was thinking of ordering the 32-bit VCI cable too, but didn't do it in the end. There are a lot of virtualization software out there to make it compatible. You can load 32-bit windows (such as windows xp) in a VM and attempt to run the cable from a virtual desktop. A virtual machine (VM) is a complete computer simulator, but it runs within your computer. You give the VM software a OS image to run and assign it ram, disk space, etc. The VCI software won't be able to tell the difference.

You would need to find a 32-bit copy of windows somewhere.

I haven't tried this before, but you can try it if you wish. I originally planned to try this out at one point. Maybe this is too complicated.

 

I "think" the laptop my son gave me had lozdoz 10 on it. I contacted the chinese guy I got techstream/cable from and he logged in and spent about 2 hours and installed it. What a ROYAL pain it was! LOSDOZ is still horrible! I wished they had a Mac version. Buttt...
I also turned the wifi off afterwards. And there was nothing on the laptop but lozdoz. But I limited what/where he could go and do, just in case.
It's worked for my on my Prius and my friends 2012 PriusV. She was greatfull to get rid of that idiototic continueous back up beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp beeeeeeeppppp

 

Look up the PDF instructions for the recall replacement of the accumulator in the early gen 3s (the one where the accumulators needing replacement were recognized by the way the label faced). I don't have the doc no. at my fingertips just now, but it's been posted about on PriusChat before.

It illustrates some clever tools and procedures that can be used to r&r the accumulator without going through all that.

What version of Techstream came with the mini vci?

 

This is an excerpt from the Repair Manual. As far as I can see, you just need to remove the wipers/motors/linkage, and the windshield cowl. Same as you'd need to do for spark plug replacement, for example.

 

I have version 10.30.028.

You could try downloading a different version and see if it works better.

I had 12.xx.124 awhile back and it didn’t have some of the menus and options, so I swapped back.

Good luck and keep us posted .

 

Yeah I see now: ugh.

 

Bringing this back... I CAN'T bleed the brakes on 2013 Prius V after brake booster replacement. I have a techstream with an aftermarket cable that seems to be working OK. But when I try to do it it tells me conditions are not met. Check and try again. I think all conditions are met (park brake on, transmission in P, Ign On Ready Off) so I am puzzled. Can someone shed some light what I am missing?

 

hi there... i am literally at the exact same spot as you right now friend... 2012 with 200k on it, actuator died totally and car started emitting high-pitches beep at all times and displaying Brake, ABS, VSC TRAC lights, along w/ a rock-hard pedal and little travel... the pump who’s telltale buzz had been getting more and more frequent over time was finally silent.

i also have a 2010 “parts car” that blew its HG long ago, that had a perfectly good actuator in it and a bad accumulator, as some 2010’s were known to have... long story short, transplanted accumulator from 2010 to 2012, refilled brake fluid, attempted bleed procedure through Techstream, make it to ‘Simulate stroke procedure’ and crash... and Techstream will continue crashing/disconnecting until l ‘reset memory’ and restart car.

stuck w/ C1202, C1345 and cannot get the codes to clear or run through the TS procedures to relearn the functions... my actuator parts are not matching numbers, does this boil down to needing the skid ECU reprogrammed to match my VIN? can i do this myself if i purchase a “professional” 2-day login for TIS? i noticed the TIS membership breakdown specifically states the $20 version doesn’t give access to calibration data... can any confirm this is my next step?

 

What dongle are you using with Techstream?

My first attempted brake bleed on my 2010 was an ordeal. I was using a Mini VCI, and it flaked out during five bleed attempts in a row, almost always on the nearly last step, when it empties and refills the accumulator six times. I finally did complete the process on the last attempt, with my knuckles kind of white because I knew I had just put nearly forty full empty/fill cycles on a six-year-old accumulator.

The next time I had a brake bleed to do, I had a different dongle (same car, same laptop, same Techstream, just a different dongle) and it went without a hitch (only I hadn't hooked up a charger to help hold the car battery up during the process, and during those last few accumulator empties/fills I was kind of urging the battery along—"come on! you can do it! just one more to go!"—and the lights were pretty dim when all was done).

 

I used to have the same problem. Last time I needed to do the bleed I had the 12v battery on a charger and it was fully charged when I started the procedure and it sailed through to the end without any glitches.

 

I am using a cheap dongle. I connected a charger to the 12V battery. I even measured the V on 12V batt (before connecting the charger) and it was OK (12 V plus with engine OFF and Ign ON). Some cars won't allow certain work if they don't sense voltage higher than 12V but I am not sure Prius is the same. To be on the safe side, I had a charger connected. Still no change.
The problem is I don't get to the accumulator bleed. It kicks me out right away. It tells me conditions are not met.
If I try to use a generic scanner it acts like it's doing something but at the end of the process nothing happens/happened.

 

Have you tried doing it with the car in Ready-On? I can’t recall if it prevents you or not. For one of these tests I chocked the car, parking brake-off and then ran it. It’s hard to hear the pump noise with the engine running but if you’ve done this before you get a feel for the timing of it all.

 

Did you get this problem resolved and get it working?
