    Working on my friend's 2013 and replaced BOTH booster pump and Brake booster with OEM today. Bleeding brakes was easy but when it got to learning solenoid valve offset, TS kicked me out and as many times as I tried (maybe a dozen times). Yes I asked TS to unlearn everything from the previous brake pump and booster. I could not get to the point in the brake bleeding process to learn the linear solenoid valve offset! I tried to do this in the ECM part of the TS but to no avail. Then I decided to drive to see how brakes were feeling, etc. and all works well. Just cannot remove this C1345 code. Tried going through the brake bleed program again and I could not get very far until it kicked me out again several times...
    Anyone??? TIA!
    Maybe fuses got blown? I have not looked yet.

    Thank you chappy! It’s awesome that you are scanning posts and always, and I mean always, a great help! I will try that this morning… What have I got to lose? Sheesh!
    Is there a way to erase all of the codes before going into this procedure? Should I jump 4 and 13 to do that?

    I tried your recommendation to jump the two wires but it did not change a thing. Nothing flashed on the dashboard and no codes magically disappeared! And this is with a new pump and new brake booster… I gave the dealer my Vin number and he gave me the parts. Just like that. Is the problem with techstream? Is the problem with one of the two parts? I don’t really know. Friend of mine says he has had better luck using an hotel OBD device. But to get to that I have to drive the vehicle some distance. Not only did the same codes appear saying that the linear offset solenoid was undone, there are also codes relating to all the wheels speed sensors. I already pulled all my hair out so that’s not going to help fix this thing… So I went ahead and put unknown good brake booster in place of the brand new one to see if possibly the new one was bad? Went through the whole techstream got all the way to the end where it asked me to do the recalibration of the solenoid linear offset thing and I got kicked out. Kicked out a text stream and I’m not sure where to go next. Thank you for any input! D94D78B1-DD5B-4831-BCA0-7442DC0B1579.jpeg

    I used TS on another car today and I noticed that it kicked me out of the most basic functions, like "Health Check". Now I am wondering if the whole problem is my Mini VCI cable...? I have had problems in years past with these cords going bad. Maybe that is the whole problem? I have never had TS kick me out of a brake bleed so many times!!! Wish me luck!

    I finally got through TS and finished the air bleed process and the Solenoid valve linear reset at the end. I had to restart TS about 10 times. What was the issue??? I wish I knew. All I can say is that I persisted and I finally got through it! Closure is valuable AND every time I work on a Prius, I learn something new....

    When you did Air Bleeding did you open 10 times nipples on calipers? Or did you just run function Air Bleeding without open nipels?
    I have the same DTC
