BRAKE( ((!))+ABS after removed calipers

tech stream

 

torque phone app maybe

also, i have read that their is a blink code troubleshooting technique on gen 2. you'd have to search here, google, or toyota service manual

 

maybe air in the system? i think you need tech stream to purge. can you order from amazon?

not sure on the fluid

 

Third gen Prius (North American model year 2010 onward) has a brake fluid bleeding procedure outlined in the Toyota Repair Manual, for doing the procedure without Techstream. It involves doing a sequence of brake pedal pushes and gear shifts, with the aim of putting the car in "invalid" mode, a special state where the brake system is more like a conventional car.

The Repair Manual for second gen Prius (like yours) has no similar instruction, just shows the method with Techstream.

That's not to say the third gen method is not worth a try, who knows. I'll attach the third gen non-Techstream method, and the second gen Techstream method.

Also of interest, watch @NutzAboutBolts 3rd gen brake bleeding video, #18 here:

Note, the video is 3rd gen, so not sure of the relevance for your 2nd gen. You could try the procedure for putting the car in "invalid" mode, who know, it might work, might have just been undocumented for second gen.

 

They don't blink codes out in normal operation, only when there is a jumper wire between the Tc and CG terminals of the diagnostic port.

 

"Thanks" to this complicated brake by wire system there are so many spots, where some bubbles of air can overdue a normal bleeding.

I think, that only with the original equipment one can open/close the right valves and switch the pump in the right time. I'm hoping for you, that I'm wrong!

 

Any Toyota dealerships in Cambodia?

 

thanks guys, this was above my pay grade

 

Mine too. Just looking at the above diagram, looks like a maze in the Sunday Paper puzzle section...

 

I was getting all kinds of problems and warning lights due to a failing accumulator pump. I found bleeding the brakes would often clear the problem for a short time. ultimately I replace the accumulator pump and did the bleeding procedure using techstream. However I was able to get the car to push fluid while not using techstream. However the procedure that I randomly came across doesn't seem to work all of the time and I don't know why.
But in your circumstance it might be worth a try they also consider that I think the Toyota dealer charge 90 bucks to do a brake bleed so it might be easier to just tow the car or possibly drive it very carefully to the dealer and let them do it.
The bleeding procedure that I attempted involved having the car in ready mode. And using something to press down the brake pedal. Cracking the bleeder ports for very short periods of time and closing them. You will hear the pump run trying to actuate the break. If you leave the leader Port open too long it will go into an error mode and stop pumping. You might be able to get some of the air out of the system using this method. I caused an error code several times while attempting this and had to restart the car and try again. But it might be worth a try. I do believe that the front brakes you can bleed manually regardless because the texturing procedure is to remove the relays for the ABS pump and then bleed the fronts as you would normally on any other car press down the pedal open the bleeder Port fluid comes out, close the bleeder Port let off the brake pedal and repeat this is much easier to do if you have someone to help you also make sure you do not allow the road so far to run low while you're doing any of this or you'll have to start over. I believe the rears are only controlled by the computer and as I said when you open the bleed ports while the car is turned on you will hear the pump run at the moment you crack the bleeder Port open. It's worth a try you already have a ton of air in the system there's not a lot you can make worse. If you only change the front caliper then you should be able to bleed it manually without techstream completely. Good luck

Not sure, I've never used Techstream myself.

I do know sometimes, if the problem is rectified, codes will disappear after about 5 start ups and shut downs. Not sure if you could just do them one after the other, or a bit of driving is needed for each. The latter is what I did, that was my experience. Anyway, it's an easy thing to try first.

If that's not working a 12 volt battery disconnect/reconnect might also clear codes??

Hopefully some others will respond.

 

In Techstream you can clear the codes after performing the procedure.

Techstream is a fantastic tool to have in your tool kit .
