Brake fluid replacement — logbook Toyota Prius 2005

It was necessary, of course, to first read the book and study the resources devoted to this topic. Who would have thought that changing the brake fluid on a Prius is so different from a similar procedure on any other car. It would seem — the replacement of filters, oils, candles — as usual. And here on you.
We started pumping — the mechanic was surprised. I press the brake, and from there the liquid directly fountains. Pumped. Leaving the box - the rear brakes do not work, the ABS, VSC, handbrake icons, the indicator of the regenerative braking system are on. I poked into the Internet, found a way to reset the errors by closing the contacts in the connector. Didn't drop. Phoned to a car service where there is a scanner. Arrived, connected using Launch. We found three errors, dropped only one and it reappeared. Well, at least the brakes worked.
Okay, priusforum users have helped. It turned out that in no case should Launch be hooked to the Prius, then you have to calibrate the solenoid, and this is done only on the scanner.
They tried, of course, to enter the calibration mode by closing the same contacts on the connector in different ways, but to no avail.
When I was already completely desperate, I found a scanner in the city, with the help of which I managed to connect and re-calibrate the solenoid.
It felt better to feel better, but once again I thought about the potential possibility of repairing the Prius in our city.
You call the service, ask for a scanner.
- Yes, of course, your model is in the database, but what needs to be done?
— Calibrate the brake solenoid.
Oh no, we don't...
