    IMG_6603.jpeg IMG_6604.jpeg I have recently bought a Toyota Prius, and at the time of buying, I used Toyota TechStream software to check for faults and the condition of a hybrid battery, and the Toyota TechStream and LiveData was working. However, randomly, after 10 minutes, the software would shut down. After trying again, it would shut down after 5 minutes. However, I was able to use that time and determine that the hybrid battery was OK and everything seemed fine, so I bought the car. The software on later tries was already turning off a minute or two later. Now the software doesnt show live data anymore, I have thought it might be that the mini Vci is bad or my laptop is so i tried another cable (jlr 165 sdd((mongoose clone)and different laptop, but same issue, It does perform health check and returns with a list of fault codes, allows me to erase them, But for live data or active test it just doesnt work, it just gives me this error, which I will upload below. Do you think that some components from my car could be broken and thus not letting me communicate with the software? Or where should I look for the issue? I will get my friend to try and check his car to see if its my car issue.

    Shut everything down disconnect everything from the car at the back of the car under the plastic tray where the 12 volt is put the battery on a tender so I'm going to call it a charger whatever you don't want it to be on the 30 amp setting or anything like that 10 and under put that on the battery and get that situated let that sit 15 minutes now retry everything you're doing have the cable connected ready the car or put it in accessory mode whatever it is you're doing one of the two and now what happens with the software when you go to look at live data or whatever
