These are out of stock everywhere, or priced crazyily, so I'm selling them to mud members for 39 via paypal/venmo. Step 1: Purchase an OBD-II / Mini-VCI interface. Hopefully this helps someone get started quickly. I also viewed some data on the TPMS stuff. Getting Techstream up and running can be a bit of a pain. I just updated the unlock so a single press will unlock all the doors.
I would be careful of what you try to update in Techstream. This worked for me… hopefully this will save everyone some time/hassle.
Towards the bottom there’s a “ConnectionCount” variable, just update this to 1 when you get close to 30 connections. To get around this go to the C:\Program Files (x86)\Toyota Diagnostics\Techstream\Env folder and open the “IT3UserCustom.ini” file. When you connect there’s a counter in Techstream that only allows 30 connections to your car without an internet connection.Now you can start and use Techstream without the force update check. The Techstream Software can save you hundreds or even thousands of dollars over your vehicle’s lifetime. Toyota developed Techstream for internal use and for customers who want to be a little more hands-on when dealing with their car. To get around this disable your internet connection (turn off wifi and/or unplug your ethernet cable). Toyota Techstream is a diagnostic and customization software for use with Toyota, Lexus, and Scion car models. If you try to Connect to Vehicle you’ll get a message that forces you to update the software.This will have Techstream use the XHorse MVCI cable. Open up Techstream, go to Setup menu, VIM Select, and choose the XHorse – MVCI.Next you’ll need to update your registry, on the ft86club post there’s a Dropbox link and with a “mvci-圆4.reg” file, download this and run it.It pops up Register Techstream Software, click on Cancel. Input dealer name / code / phone / Country, and then click on OK. When it asks to register with a new key, use the key found in the “serie.txt” on the CD. Copy Techstream Patch 64bit from the folder Open Techstream Configuration (S822-04), select the Area Other and then Next, then English. You should be able to load up the Techstream link that was installed on your desktop.After installation I went into the C:\Program Files (x86)\Toyota Diagnostics\Techstream\bin folder and replaced the “MainMenu.exe” file with the one found on the CD. Next up is the Toyota Techstream software, from the included CD I ran the “Toyota Techstream 10.30.029.exe”.
I used the “Mini VCI Driver for TOYOTA.msi” in the 10.30.029 folder that came on the CD. Follow the steps outlined in “ Installing MVCI Driver for TOYOTA” of the ft86club post.
