Master Cylinder Brake Fix with Techstream

Just posting to let you guys know of what I experienced. Might help some People out there. So I got the dreaded Faulty accumulator leak. My symptoms was it would buzz every 5 secs car still brake and drove just fine. I had 160k miles and it's 10 years old so I missed the extended warranty date. I decided to only replace the master cylinder. I bought it brand new for 900 bucks from a toyota online dealer. Installation was easy, but techstream was nightmare. It would throw errors at the stroke simulator part. Also battery was low. My fix and this worked for me and my setup. I had to use jumper cable from another car and keep it running while doing the steps (this kept the battery at the correct voltage)
1. First I would do the Air bleed (replace accumulator Option).
2. then I would do the air bleed again but use the Air bleed only (I just skipped all the steps, just make sure you got all the bubbles out. it got through all the steps successfully for me).
3. I would reset the memory
4. I would go in ecb submenu
5. do Linear Valve offset (if the lights are flashing like it says in the instruction and you hear the pumps working then it's not working correctly)
6. clear any dtc codes. and should be good from there.

 

if meant it is working correctly if you hear the pump working and the lights are flashing
