Default Techstream problems with 2008 GS460

Hi all

Just purchased a techstream adaptor to use on my 2008 GS460It included V13.00.022/V14.20.019/V15.00.26 of techstream
Also multiple drivers
Only driver I could get to work was Autokent

No problems connecting to VIM
However once I got into the customizations menu, the only options which work are tilt/telseco and air conditioning
The others load for a few seconds then the box disappears.

Tried various earlier versions of techstream including 10.30.029 (fartherest back I tried).
No idea what firmware version the cable is running
Tried windows 10 and windows 7

Anyone else with a GS460 had better luck?
Or any other advice from others?

Windows 10 and Techstream 15.00.026 work perfectly fine on my car. The more recent, the better, because features could have been added or bugs fixed even after the model was made. What is available in the customization menu depends on which ECU you're in. Do all the ECUs respond? There are 5 or 6 separate ECUs just for the cabin equipment, so maybe you were in one given ECU, which controls the A/C and the steering wheel adjustment. When you select (single click) an ECU, what it controls is in the description below.

I was never able to get techstream to work on my computer, I tried so many downloads, and read many tutorials and troubleshoots. Maybe try another computer

Most ECU all respond back fine, can view them and check them
Going into customizations will load 70% of them and I can go into the ECU menu on the main screen for all of them fine
But when I try to change anything in the customizations menu is where I get the problems
For most of them I click to load the customizations and it pops up loading then the loading box just disappears. Even the basic ones such as door locks (for unlocking all or just some doors with the keyfob).

Hello.

New joiner here. I have the same issue with my GS450h 2006. Doesn't matter if i single click and then click the arrow or double click the configuration ECU. The box just says loading and then it just disappears. I have also contact with the ECU's and can read info from them.

OK, now that's surprising. And I'm usually unlucky, and run in as many issues I possibly can, but as far as Techstream, I curiously didn't.

I think the OS isn't the problem. If it was, the software wouldn't run or crash. If it runs, the OS won't (or is unlikely to) affect its particular features.

Same for configuration files, it would crash if they were corrupt or missing.

This is clearly a bug, because if the software was done right, it would clearly tell you what's wrong, and in this case, the error is not handled, and ignored. But with that in mind, only one thing remains: the adapter. Even cheap ones saying "mini VCI" should work, but we never know. I don't say this is indeed the culprit, but this is just what comes to my mind. So you could try buying another cable, or get the same adapter as I have. I have a wireless VXDiag VCX Nano connector, here's what works for me. It is a bit expensive, but it has good reviews and if you buy the wireless version, you can connect the car to a computer in your garage and you don't have to sit in the car uncomfortably with a laptop.

Yeah, was thinking it was the adaptor as well
I'm thinking of contacting the local clublexus group and try out someone else's then buy the one that they have if it works
