Toyota Techstream Diagnostic Cable Mini VCI J2534 OBD Scanner V2.0.4 for Toyota Lexus TIS Techstream (Updated Version)

It worked for what I needed!I had replaced the transmission/engine in my 2014 scion tc and had also done a full service on the transmission before putting it in the car.I needed a scan tool with high enough diag level to reset/relearn the transmission control module values along with writing the new transmissions compensation code to the ecu/tcm.I didn't use the software given due to trust issues with foreign softwares on my laptop. Instead I used a slightly older version through a remote desktop that you can access by looking up on YouTube or a Google search with the title "how to get techstream in 5 mins"Worked well! Can't beat the price.

I received the cable and CD, unfortunately I do not have a CD drive so I emailed support and they promptly responded with instructions in 3 hrs.Even before they responded, I googled and was able to find v18 Tech stream software and the necessary drivers and instructions (on Google and YouTube)The instructions online were the same as sent by the vendor btw.Installed it on a win10 home 64bit laptop with zero issues, and it's working great. I'm not sure what the bad reviews are about? Yes it takes a few steps to installed and for those who are not savvy with computers the vendors offers to remote install, that's how tech support works guys, there is no conspiracy hereGreat product😆 great vendor, I can access all of my vehicles data, program tpms, keys, what not.

Update: The cable does not support adding TPMS sensors. This is a deal breaker.This is a great tool if you have a Toyota product (Toyota/Lexus/Scion) and work on it yourself.I was able to get it set up and running on a MacBook Pro running VirtualBox and Windows 10 64-Bit. Cable is sturdy, loads fast and is the new firmware version. LuckyBuy11 has been a good vendor.

On the CD there is a video tutorial, which is not too easy to follow. There is also manual.txt file with instructions which are not accurate or clear. I am giving this product 4 stars because the installation instructions are not very good.I have outlined the steps which worked for me in Win 10 64.Installation procedure for Techstream and Mini VCI Cable.Assuming your CD Drive is the “D” drive. When references are made to the “D” drive, I am referring to the CD drive.1. Run the video codec file ”vlc_2.2.4.0” located at “D:\Video”. Then run the tutorial video “WIN8 64 MINI VCI EN VIDEO”located in the same directory. It is difficult to follow, but the steps below should help guide you.2. From the CD read the file d:\Manual.txt3. Decide if your PC is Windows 64 or 32 bit. I am now referring to a selection of Windows 644. Disable your Antivirus program5. Have Java installed6. At the path “D:\Software\WIN7 8 10 64bits” run “Techstream_Setup.exe”7. When Techstream _setup has completed installing, go to the path “D:\Software\WIN7 8 10 64bits\Program Files (x86)\Toyota Diagnostics\Techstream\bin” and copy the file “MainMenu.exe”8. Paste the file “MainMenu.exe” at the location “C:\Program Files (x86)\Toyota Diagnostics\Techstream\bin”. If there is an existing file with the same name, replace or overwrite it.9. Copy the directory “Xhorse Electronics” at “D:\Tool\backup” and paste it in the directory at “C:\Program Files (x86)”.10. Run the file “MVCI-64bit” file at “D:\Tool\backup”. This file will make an entry in your Windows registry.11. At the directory “D:\Software\WIN7 8 10 64bits\Program Files (x86)\Toyota Diagnostics\Techstream\bin” open the file “SN.txt” and copy the registration key number listed in the file.12. Start the Techstream software. Select your region, if North America you can use “1” for the Dealer Name, Dealer Code, Dealer Phone. This was shown in the video.13. You might want to disconnect from the network/Internet at this stage.14. In Techstream select the “setup” tab and then “VIM Select” and select the “XHorse MVCI” adaptor cable. Go to the “Registration” section and paste the registration key you copied in Step 11.15. Plug in the Mini VCI cable in the USB port. In Windows “Device Manager” you would see the USB to Serial cable added as a COM port. Select this port and choose “Update driver”. Select the path for the driver to be “C:\Program Files (x86)\XHorse Electronics”. Windows may say the best driver is already installed.16. Connect the OBDII cable end to your car’s port. In Techstream you can now select Connect to your vehicle.

If you are looking for a techstream cable and have a newish car (mine is 2019 for example) I'd spend the extra money and get this cable with the 2.0 firmware instead of the others online that are cheaper but are 1.4 firmware. I bought a 1.4 firmware first and it didn't work with all the functions of my car. It'd crash the software when trying to read engine live data and it wouldn't program keys. I upgraded to this cable and everything just works now. Worth it and I wish I knew this ahead of time.

Cable works good, but couldn't read live data using the installed software (version 13). Program kept closing whenever I tried. Had to install version 12 software after downloading online, before it worked. I'll buy just the cable for cheaper next time and download software for free.

This is a difficult product to install. And just like many here I needed help from customer service to install. Giving access to someone to go on your computer to install the software is a scary thing. But I did it and I am thankful I did. This software worked very well once it was installed. I have been able to connect to all my Toyota’s and even programmed a key fob to my Sienna. Saved me hundreds of dealship fees. Thanks!

The seller provided instructions on how to overcome the error (same instructions that I had found elsewhere) but this did not work. I previously purchased a less expensive version of the cable on eBay and had the same problem programming the TPMS sensors. I purchased this 2.0.4 version of the cable after research indicated that the 2.0.4 version would solve the problem, but it did not. Ultimately, I purchased the VXDIAG VCX Nano which worked with no issues on my 2011 Camry.
