SpaceManX

Bought a used 2015 Lexus es300h and went to clear codes but when I tried to calibrate the angle sensor it failed to communicate and turned my EMPS off. Did research and bought the mini Vci cable and tried but failed to get the techstream that came with cable to work. I had no idea how to use the computer to get it to work and for that last 2 weeks been downloading only god knows what trying to get techstream to work and have only failed. Very very frustrated ready to just shoot both computer and car but figured I send out a prayer with the hopes someone here can help me!
