Brake electronic issues

i think you've lubed those puppies one too many times.

 

D0H recall cone on that pup, Mendel?.. Mine has had it but I'm still leery of the brakes on the 2010's.

12v battery and connections?

 

1. Check the tire pressure at all four wheels.

2. Get Mini VCI. The skid control ECU has logged DTC given the presence of the ((!)) light.

 

all the best mendel, keep us posted.

 

If I'm not mistaken ... I've seen at least one post confirming the Gen 3 braking computer still can do the blink-codes-on-the-dash-lights trick just as Gen 1 could, if you're in a pinch and don't have a CAN code reader you can use. Have you tried that?

You are not mistaken.

In that case, please post a sharp photo of the warning light(s) that is(are) producing the blink codes when you report which light is producing which blink code.

 

Do auto parts stores in Canada have free loaner code readers like they do in the U.S.?

 

It's probable that they do ... and also probably that, just as in the US, they will lend you a code reader capable of reading maybe one seventh of the diagnostic information you need from a Prius.

The thing is, you sort of need to be a regular reader of PriusChat to have heard which code readers are the useful ones, and too few of the people working in auto parts stores hang out on PriusChat.

This will be interesting to follow, Mendel. Since we really haven't heard of any issues, I'd guess the brake booster replacement is not prone to failure. And since you've done the updated rear pads/shim kit and had the D0H, and have generally been the most observant PC-er of the marginal brakes (rear, anyway) on certain 2010's, it's sort of ironic this is happening to you.

My feeling, after having the D0H, carefully filing the caliper brackets of corrosion and following the TSB pad/shim/clip replacement procedure, is that the rear calipers are simply weak at best. Of course this could be a caliper issue or the front/rear bias could be off or who knows what. Hopefully your local dealer is strong (and honest) in the back-shop.

And you are for sure a great mini VCI candidate. I can recommend a ~$60, XP-running, Dell Latitude from ebay. These are stout laptops with a reputation for being bombproof. I recently "upgraded" from a terminally ill EEE PC and scored a 620 Latitude ($63 shipped) which runs like new. Follow dolj's post #11 install procedure Using MVCI: cannot connect to VIM error..... | PriusChat to the letter for a pain free set-up. Turn off antivirus during install and also before opening Techstream. If you dedicate a laptop to mini VCI, don't even bother with antivirus. If antivirus flags the complimentary MVCI trojan while opening Techstream, it can cause connection-VIM issues, meaning you won't be able to get Techstream to connect to the vehicle.

Good luck,

Mike..

 

That's an interesting link ... do you happen to know who runs the site? It says very little about itself, but it has a "Donate" button to "help keep workshop manuals freely available."

I would be totally psyched about donating to a legitimate company if it had reached some agreement with Toyota and other mfrs about compensating them fairly and putting the stuff freely on line. On the other hand, if it's just Fred Phishnik trying to collect as many PayPal donations as he can before the mfrs take his site down, not so much....

For what it's worth, it does seem to be a genuine PayPal button (and not, for example, clickbait to somewhere else). If you click it, you're paying "donation" at "workshop-manuals" dot com... whoever that is.
