I just purchased a 2007 Prius that is throwing this c1345 and also the c1368 code. I am using the techstream and have bled the system. I have attempted to initialize the linear solenoid valve and recalibrate after resetting the memory. The solenoid will not initialize or recalibrate. Am I looking at replacing the Brake actuator assembly?
We do hear of the Brake ECU failing from time to time here. Since a used one is cheap, and it is a plug in unit, that would also be something to look at.
