Anyone has Toyota Repair Manual about Brake??

[hsujohn]

I recently ordered the AutoEnginuity ODBII scanner which they clamied to be working same as Toyota Facotry scanner when doing the brake bleed. When I looked at the internet repair manual about brake bleeding, the procedure is totally different from This PDF The program told me that first step is to loose the brake bleeder on the right wheel but I don't know if it's front or rear wheel first?????

I tried to call the AutoEnginuity tech, but didn't get much help beside that they are sure that it'll work but I need to look at the REAL "Toyota Factory Repair Manual" because their scanner is designed to be working same as Toyota's.

So I am here to ask that if anyone of you have the Factory Toyota Repair manual, can you please please look up the section about the brake bleeding for me? Please check if it's any different from This PDF Please tell me the procedure, a scaned PDF or text file..etc, anything is better than nothing, I really hate to see that I spent $400 for scanner and need to spent more money then find out that scanner don't work..................


thank you so much for the help and have the happy holiday

John,
The 2006 service manual looks like the same thing - the tool tells you to do both sides of the front and then move onto the rear wheels. It is supposed to tell you RR or LR as it runs the pump. Look at the first pages 32-7 and 32-8 of the PDF you referenced. I used to do stuff like rebuilding brakes and bleeding them, but the tools required and the number of pages in this procedure scares the h--- out of me. I think I am done with working on my own brakes (or anyone else's).

John,
It looked like a complicated procedure. I hope you had success.

Please let us know how the AutoEnginuity scanner worked out for you. I'd consider getting it for myself as well.

Your PDF is right out of the Prius repair manual. Same page, same version number: 32152–01
Even the bottom of the page says: 2004 PRIUS REPAIR MANUAL (RM1075U)
So the question is, what are you finding on the internet that's different?

[nicoss]

The Toyota 2004 repair manual states that if the bleeding is done incorrectly there is a possibility of an accident.

This statement alone and the fact that the manual is written around the Toyota tool would have stopped anybody from continuing that:
a) Does not have the Toyota Scan Tool
Is doing the bleeding on a PRIUS for the first time
c) Ignores the fact that although there are some incompetent dealerships there are many more incompetent DIY and servicing a car is cheaper than paying for broken bones.

As far as AutoEnginuity, they can claim whatever they want. Will they back it up if you happen to lose your brakes and crash??

For Toyota repair information, go right to the source:

http://techinfo.toyota.com

You can purchase a subscription for just 24 hours, or much longer, and be assured the information you get will be reasonably correct and current.

To bleed the brakes on the Prius is very involved, due to the electric boost pump and - my favorite - the "stroke simulator."

<pause to allow snickers and giggles to subside>

If you get the bleed procedure wrong, you could end up with air in the brakes. I've always believed in flushing/bleeding my brake system every two years, which is easy enough if you have a helper to tromp on the brake pedal when necessary. I knew this was clearly not the case with my Prius, so paid $88 to have them do it a couple of months ago.

That is, in fact, a section from the Toyota manual and I put it there
as a supplement to this post to point out A> the complexity of the
procedure, and B> that Autoenginuity did *NOT* have it right yet
with regard to the brake system. All the scantool makers are up
against a bunch of incomplete information from Toyota, with a certain
amount of favoritism given to Mastertech as the official "Toyota
hand-held tester". Everybody else loses.
.
So the useful bit you've found is that AE is still not on top of this
stuff, and no prognosis as to when. Jay's pretty busy and will
hopefully get around to it someday, but possibly not until Toyota
finally quits hiding stuff from the independent toomakers and techs.

I guess I would go with the majority here. Toyota is not talking and not giving away details either. The scanner may work well but does it have the Toyota program in it. I would guess not and if they "borrowed" a copy they run the risk of copyright infringement. I had always assumed that I could get the brakes replaced anywhere. Breaks are breaks. I read the referenced materials (I have a copy of the manuals) and I am no longer so sure. I think we may be tied to the dealership more than we thought. On the happy side I have 40k on the car and more than 80% of pads left on the car. I will get a new car before the pads are gone.

No promises on when or even *if* I'll get around to it. The biggest single detriment I have to pursuing this any further is the legal issue.

I managed to pick up the ECU and HVECU from a totaled 2005 Prius at auction. Next step was to use my 2004 as a guinea pig to see if I could characterize the signals, or manage to do something dumb like deploy all my airbags in the process.

If some folks didn't know, late last summer I finally managed to "borrow" from work a new and very expensive Agilent 54600 MSO (Mixed Signal Oscilloscope), the Agilent N2758A trigger module, and the appropriate OBD/CAN dongle. SSssshhh, don't tell anybody at work.

We do a lot of CANBus development for the industrial process control industries, and recently Agilent started bundling their CAN trigger modules with *all* the generic CAN messaging. It will pretty synchronize on trigger SOF (Start of Frame) to any CAN or LIN, even to I2C and SPI. The neat thing is that it will trigger to Standard ID and Extended ID, even a mixture (11 bit and 29 bit). With LIN it automatically triggers on the rising edge of the synch break exit.

One of my co-workers and I spend the next several weekends going over things with the Agilent. We did manage to get access to the obvious OBD things, like resetting the MIL, along with some MFD diagnostics. I’m leery of extended access to things like airbag settings, and the Trac, but it would be nice to momentarily trigger a desensitized Trac when you’re stuck or about to get stuck.

I will reiterate that I see no obvious evidence that Auto Enginuity has properly set up the complicated brake bleed “dance” the Prius needs. If an individual wishes to trust their scan tool to properly and safely flush/bleed the braking system, caveat emptor.

i was talking to a toyo hybrid tech yesterday (since i'm at a work term for a toyo dealership) and he told me he has never done a full procedure of bleeding prius brakes. He's done ABS bleeding on the camry hybrid before but he couldn't remember the last time he's done something like that, and he was unaware of the scan tool the prius uses...
