I figured out what went wrong and it's working now.I downloaded TechStream 18, but it wants a key. What am I missing?
I figured out what went wrong and it's working now.
My install was based on the instructions on VXDIAG. A few things that I've changed from previous install:
1. Plugged in the dongle before running VX manager. Make sure you see the dongle in the VX manager app.
2. Do NOT open Techstream using the the real Techstream icon that was created on your desktop. You have to go to the BIN folder and use the Toyota Launcher application, it will automatically bring up Techstream. By doing it this way, Techstream no longer ask for the Key. I created a shortcut to put on my desktop so I will not need to dig through the folders to find the Toyota Launcher next time.
3. After Techstream is loaded, go to Setup>VIM Select> open the dropdown and choose TOYOTA-J2534. This is something that's not listed in the instruction but it's super important because the default is TIS Techstream VIM. If you don't choose TOYTO-J2543, your dongle will not talk to your Techstream.
4. I have a press button start car. Press the start button on the car twice. Connect your car to the dongle. Click connect to vehicle in Techstream and you should see your car's information automatically populated.
Good luck!
So I found this on the VXDiag website. It is open for public so I think you should be ok downloading this. They have version 16, 17 & 18. VXDIAG Diagnostic Software Download - https://www.vxdiagshop.com/info/download/
Seems like v18 can be installed on Windows 10, it should run much better this way, right?
Why? Launcher has virus?Correct, just be careful which "launcher" you use, or run Techstream in a VM or on a machine you don't care about.
Why? Launcher has virus?
Highly probable especially the launcher from this link provided by VXDIAG:
![]()
File folder on MEGA
mega.nz
It's 7 MB when other launchers can get the job done with a few hundred KB.
Download it but don't run it then check it's CRC/hash and behavior here:
Results not conclusive. Some antiviruses seem to know what it is and don't mark is a virus. Hm..

Unless home mechanics for Toyota vehicles is some sort of high value target, my bet is the size and virus hit are related to how it was cracked to not phone home and need a key.One thing I would suggest - if you opt to use this sketchy .exe, then disable your network devices in your VM, ie don’t let it connect out to the internet, keep it isolated.
Per the malware sandbox sites I linked above, the launcher .exe from VXDIAG’s site seems a little sketchy, to put it mildly.
FWIW - I work in offensive cyber, so I’m not a blue team guy doing malware analysis. But I know enough to know that that .exe seems suspect.
