Diagnose Toyota Supra J29 with ISTA and Techstream
How to use Toyota ISTA to diagnose latest Toyota Supra J29 vehicles?
Step 1: Download Toyota ISTA from the official Toyota website. You don’t need to sign up or pay for
anything.
Step 2: Install Toyota
Techstream and activate it.
Step 3: After activation of Techstream,
install ISTA. Toyota’s ISTA checks for an activated Techstream install. Due to
that, there is no need for additional activation in ISTA.
That’s all you need. If you want to use the psdzdata from the ISTA install
for ESYS, type this command into CMD as administrator:
MKLINK /d
“C:\Data\psdzdata” “C:\Program Files (x86)\ISTA4J29\PSdZ\psdzdata”
I was able to successfully do flashing using ESYS 3.30.1. I was unable to test coding as I was using a VM and launcher pro won’t activate in a VM.
NOTE:
If open ISTA J29 and get a window titled: “Toyota ISTA usage notes” and there’s an “X” to close it. But if close it the entire software closes as well.
How to bypass this message screen or how to go to the ISTA menu?
Switched resolution to 1280×1024 and is able to see the agreement acceptance button. That window is gone.
VXDIAG Cannot Auto Identity New Toyota Tundra Solution
Problem:
When I tried to connect VXDIAG VCX NANO Toyota interface on two Toyota vehicles—a 2023 Toyota Tundra and a 2015 Toyota RAV4—I found that the device could not automatically identify the models. I have attached some photos of the issues below.
Solution:
This raised concerns for me, particularly regarding the compatibility of the new Tundra. To resolve the issue quickly, I contacted VXDIAG customer service. Their response was very prompt, and after a thorough inquiry, the representative suggested that I select the correct region in the software settings.
Following their advice, I accessed the settings menu and chose “North America” as the region. After saving the changes, I attempted to connect again. This time, the device successfully recognized the models and proceeded with the diagnostics. I look forward to its continued performance in the future. If necessary, I will provide updates on my experience, and I hope VXDIAG won’t let me down!
VXDIAG Toyota Smart Key Programming Asks for Pass-code?
Problem:
Received the vxdiag vcx nano Toyota cable and set up Techstream 18.00.008 software on Win10 laptop. Tried to program a spare smart key on a 2022 Lexus NX350h. Techstream software asks for a pass-code.
Here is the clue.
The newer Toyota’s have an extra security component even adding keys diagnostically will be a problem unless you have the special password.
These rolling code changes every time you plug in. You can buy code online directly or have other tools to bypass the pin code.
Best bet is Techstream subscription with NASTF.
It’s the $65 security professional script. If you have a yearly subscription there is no cost. The yearly subscription costs $1,295.
You can purchase a 2 day subscription at a cost of 65 dollars. Then you have to wait for email ( up to half hours) then you can re-log back in to site and get 1 free key code. It’s much quicker to just pull out the drivers door lock cylinder and get the key code. It’s stamped right on it!
If bypass the seed code, there is no option for all keys lost or generate smart key, only add key, then add the key.
Once you have reset immo, you go back and add key.
VXDIAG Benz 2024.03 Xentry No Access Authorization Code?
Problem:
One of our customers had a problem running Xentry 2024.03 for VXDIAG VCX SE Benz scanner.
When running xentry software, it said ‘No Access Authorization Code’.
Update firmware, reinstall C6 driver, run FIX recovery on desktop, all no luck.
Solution:
If had ‘No Access Authorization Code’ error, needs to disable security boot in BIOS setting.

Failed to Open VXDIAG Toyota Techstream Patch Solution
Problem:
One of our customers bought the vxdiag vcx nano Toyota scanner when he tried to crack Techstream in Win10, he managed to run the patch – Toyota Launcher.exe– as an Admin, it runs and see that Toyota picture, but then nothing happened.
When opened Techstream and it said I had 3 days until he had to introduce the activation key.
What is the solution?
Solved:
Set-up Techstream as usual until it asks you for the Serial Key AND then always open Techstream using Toyota Launcher.exe
The long one in case you didn’t get it:
First of all, Go to Control Panel > System and Security > Windows Defender Firewall > Turn Windows Defender Firewall On and Off (left side menu) AND turned everything off. The Toyota Launcher.exe will be identified as a trojan otherwise and you won’t be able to run it.
Techstream installed – fresh install, copied Toyota Launcher.exe in the Bin folder for Techstream (see tutorial) , VX Manager installed and updated VXDiag dongle to date.
Now, technically Toyota Launcher.exe should open Techstream and you should do the Techstream set-up – company info, location etc. That’s what the VX Diag tutorial tells you to do. But in his case it did nothing. He saw the Toyota picture/logo on grey and they it closed and nothing else. SO:
He opened Techstream from the original exe icon shortcut on
desktop and did the set-up filling the boxes exactly like in
the tutorial (enter the same numbers and whatnot – until it asked for the
Product Key. CLOSED Techstream. Then went into the Bin folder of Techstream
where you’re supposed to copy Toyota Launcher.exe and double clicked
it again and now it should open Techstream after a few seconds. Now you can see
2d23h59m in the left corner, no key is required and you can connect to your car.
Always use Toyota Launcher.exe to launch the
program. Delete the original icon shortcut on your desktop and make a new one
based on the launcher exe.
The End.
PS: turn on your Win Firewall Defender after you’re done. Toyota Launcher.exe will work after that. If Defender still bothers you, then add the .exe as an exception, go to defender and search the warning and tell the program to leave that .exe alone.
Hope it helps.
