Mini VCI Techstream V12 on Windows 10 64bit

I have a Mini-VCI J2534 cable which worked happily with my Techstream 10 install on 64 bit Windows 7, after some faffing. Anyway, had to give that laptop back last month when I left the job I'd acquired it from.

Windows 10 has a few more challenges. You need at least Techstream 12 (you could hack about with the registry to get Techstream 10 to work, nit don't waste your time). And you need to get Windows 10 to load 64 bit drivers for the cable. Windows 10 really doesn't want to let you load old, unsigned drivers. You can do it, but it'll make it hard for you.

So a bit of googling and a bit of trial and error and these steps seem to work.

Follow the steps under : Techstream install Windows 10.

Step 2. You want to run this from the cmd prompt as the admin user. (type "cmd" in the Type here to search box in the bottom left of your screen)

Step 4. Copy all of the contents of the file in the link to notepad (dont copy and paste from the steps, there are extra spaces in there), and save as filename.reg

You then import that file using Regisitry Editor (type "registry" in the Type here to search box). Select the import option from the File menu (top of the screen).

Some instructions suggest running a firmware update tool to confirm the cable install has worked; but the tool doesn't work in Windows 10. Don't waste your time like I did!

Step 7. You can get Techstream 12 online. I did virus check this, but .. at your own risk. To extract this file you need to copy it to the desktop then open it with a zip program, such as Winzip. You may need to download that from somewhere.

Check the instructions.txt in the unzipped files. Theres a few simple steps to complete the install.



All working fine now. 

How to Get Mini VCI COM3 Recognized by Mac Pro VMware

 If anybody is using a HOST (meaning your main computer you are using) Mac machine and a Windows VM using VirtualBox, here's how to also get your PORT(COM 3) recognized in the Windows VM. This is important because the cable I ordered needs the drivers for the USB AND the PORT(COM 3) installed. If your Mini VCI cable does not require for this, then please disregard.

On your host mac machine:
1. Plug in the cable to your computer
2. Open terminal
3. Type: ls /dev/tty.*
4. Press enter
5. You should see something like this listed: "/dev/tty.usbserial-A6007dAe". Copy this down.

On your VirtualBox with your cable plugged in:
1. Right click your VM and click "settings"
2. Click "ports" at the top
3. Click "serial ports"
4. Click "port 3"
5. Click the checkbox so that there is a check for "Enable Serial Port"
6. Where it says "Path/Address" paste in what you copied above ^ (/dev/tty.usbserial-A6007dAe)
7. This is the information you should have shown in the picture below
8. Start your VM
9. On the top of your VM, click "devices" -> "usb" -> click enable M-VCI
10. Go to your windows search bar and search and open "Device manager". Or, right click my computer, right click "C drive" and click settings. On the left you will see device manager
11. After opening device manager, click "PORT" and you should see "PORT(COM 3) there or something named similar.
12. In device manager, click USB and you should see your USB enabled there as well.

Hope this helps.


Verified working for Mac 10.14.13 and Windows 7 x64 VM and cable version 1.4.1

Mini VCI Techstream Bleed the Brakes on Toyota

 Tutorial: how to bleed the Brakes on your Toyota/Lexus using Toyota Techstream software on a laptop.

So many ways to bleed brakes, just adding this one to the tool belt. Seems like an efficient way to push a higher volume of fluid so may be a good option for a full flush, especially when time is short.

 

Model example: Land cruiser LC200 series.

Background:

Finish a complete break upgrade on a Land cruiser 200 series.

 

Procedure:

Get a cheap mini vci cable and proper software version.

Here v12 (older version has the Unitiny feature) was used and set it up on VMware Win7 32bit.

Insert mini vci obd2 cable into car

Connect the vehicle, now go into the ABS vehicle stability control on traction

Go to Unitiny->Air Bleeding

It tells us here that this function is used to purge air from the hydraulic braking system

and then we just follow our prompts.

I am going to start with the rear left line which is the furthest line from the master cylinder.

i’ll hit the next button and it says here perform the following operations.

open the bleeder plug.

you see the bleeder plug is open.

because we’ve got gravity dripping fluid through it.

press the next and wait for the timer and it says note do not depress the brake pedal.

now we’ll hit our next button and you can hear funky stuff happening under the bonnet.

now it says please perform the following operations close the bleeder plug

close off our bleeder pug press next

wait for timer

hit our next button and it says resetting what that actual resetting is i’m not sure but it must have something to do with the master cylinder.

air bleed is complete. press next to select another line or press exit to exit the function.

i’m going to hit next i’m going to do that right rear line again and i will show you what it looks like at the master cylinder.

here’s what it looks like at the wheel cylinder

and our air bleed is complete on that right rear line.
now i will continue to  do this process i will repeat it about five times per wheel cylinder just to make sure that i get all of that air out.

i’ve got plenty of fluid i’m pushing dot four fluid through it now.

now the front left is a little bit different in that it asks you to hold the brake pedal

then press next let the timer run its course and then release the brake pedal and press next that’s quite interesting so it looks like it doesn’t actually bleed fluid through the wheel cylinder

and let’s try the front right same thing.

press and hold the brake pedal hit next, without releasing the bleeder plug then release the brake pedal and hit next.

so on those two front wheel cylinders i will open the bleeder plugs and just let gravity bleed through there and push any air out that might be sitting in those wheel cylinders.

CAUTION: If air is bled without using the Techstream,damage or accidents may result. Therefore, always use the Techstream when bleeding air​.
Worked great for me.
