GM Diagnostics FAQs (MDI, GDS2, Tech2win)

Good questions and answers of GM diagnostic test. Just share some i think good to share with you all. Hope it helps.

Question: That screen does look exactly like my Car Diagnostic Tool Tech II menus. Some sort of emulator I’m guessing. Nice find.

Edit: Curious how you connected the laptop to your obd 2 port?

Answer: you plug the device into the OBD2 port, and then you either use Wifi back to the laptop to connect that way ($129), or you can use a usb cable instead ($119).

Even through the device is using GDS2, GM MDI Scan Tool and Tech2win software on the laptop side, the only thing that I have to question is if you can drive firmware upgrades through it to reprogram modules if needed as well?

Now the bad news that maybe the op can bring us up to speed, did you mange to get the tech2 win to install on a 64 bit machine with 64 bit windows, or did you install tech2win and the rest of the software a 32windows machine only isntead.

Question: First GDS2 works with the included software as a virtual machine with VMWare running in a decent hardware, no low end Pentiums or Celeron, please Core2Duos and up, Minimum 4GB Ram, etc..

Second and thanks for the seller assistance, Tech2Win works ONLY in a physical system with Windows Xp or Windows 7 x86 (32Bit) installation. It does not work any other way. It DOES NOT WORK in a x64 (64Bit) environment. Did I say only 32Bit?

Answer: Truth is, for $119, would just about cover what most are using the tech II for on the vet anyways, but still back to the question if you have to have a X86 machine (32 bit machine with 32 bit windows software) to load the needed tech2 win software to, since it does look its a no-go on a X64 machine with window 64 bit windows install , and even a no go of trying to VM a X86 shell to run tech2 win that way on a X64 loaded version of windows on a 64 bit machine instead.

So the real question since most of the newer laptops are 64 bit, and running windows 10 64 bit, is this what you loaded the software to, and had no problems running it? Or did you have a 32 bit machine laying around to load the software to instead.

Note, there is a work around to get a 32 bit program to run on 64 bit software, but it no joy, and not sure how its going to reach to GDS2 running in a VM shell at the same time.

Question: I am no IT smart but still have to ask, how do you make the connection between the GM VXDIAG VCX Nano and the computer?

Answer: it connects via a usb cable that comes with the device and then the device itself connects to your cars OBD2. Yes you can even reprogram modules. Its basically the same you would do it with the clone Tech 2. You use the GDS2 software. It comes with the device, but i’m not sure if its a cracked version and would still require one to obtain a subscription from the ACdelco website (some one will correct me if im wrong). I’m not sure if there is some kind of test i could do to verify that without actually reprogramming a module???

Question: Now that I do have the tool, and living in a high humidity area, how to turn the HVAC after blow on.

Answer: Connect the scan tool.

Turn ON the ignition, with the engine OFF.

Select HVAC Module.

Select HVAC Systems Automatic.

Select Special Functions.

Select HVAC.

Select Afterblow Option.

Select ENTER to enable the afterblow.

When done, use the soft key to save changes.

When afterblow has been enabled by the scan tool the blower motor will operate between medium and high speed for 4 minutes after the engine has been turned off.

Good deal. Not gonna lie, wish i had more stuff to do with my car so i could play with mine further. But i will look at the HVAC option.

I fired up the GDS2 software and that indeed runs off Windows XP. But it does come with the VM software. So far everything works under my Windows 10, but like i said the GDS2 is running in the VM software.

Vediamo M Mode Variant Coding W212 7G

Some important tips of Mercedes Benz W212 7G M Mode Variant Coding using Vediamo.

Purpose:

W212 7G M Mode Variant Coding

You need:

Vediamo running with Sd connect C4

SCN coding database

Variant code:

Y2KY

BetaMar

I want to have M-mode in W212 E500 4matic 2010 model 212.090 SA801 – YOM 10/1, at the moment my variant code is Y2KX, does anyone help me to know the right code for M-mode ?

StarRacer

That’s interesting. I’ve got nearly the same car (W212 from 2009) and I’m also looking for the manual mode. My variant code is Y2KY.

Someone recommended to try three codings before and after the current one but I’m a bit hesitant with this.
The coding contains several properties of the car including 4Matic or RWD. In contrast to the RWD ones, the MB Star have a torque limitation to protect the gearbox etc. when starting with full throttle. Therefore, a genuine 4Matic variant code would be preferable.

I think in the 7G coding collection there was no W212 E500 with M-mode. The next “match” could be an S500 4Matic (221.086). From the thread mentioned its variant code is YE25. Not sure if this one has M-mode, though.

BetaMar

I want to confirm that in 212.090 with MY2010 SA801 M-mode work very well

with Y2KZ ?? Imidietly after coding there was error showed in KI display “presafe function is unavaiable” but after ignition off/on everything works!

For 212.090 MY2009 SA800 correct coding is Y2AR

StarRacer

SUCCESS! Now with working M-mode! Y2KZ also works for me. Same error as above after first start which went away with the 2nd start.

Test drive was successful. One drawback, however: The gear switching times in M are not better than in C or S. Some years ago, I read from an S211 (E500 M273 with 7g) which was given M-mode and the owner claimed significantly faster gear switching. He did it the official way: Changing VeDoc and MB Star C4 online SCN coding. Maybe there’s more to it than just the VGS variant coding.

Good luck

PIWIS II tool now for sale

After surfing the net looking for some goodies for my ’06 C4 I cam across Porsche Piwis Tester II. This company Obd2tool.com is selling the PIWIS II system, it has offline and online functions, to support ONLINE function, valid certificate must be available for Porsche Piwis Tester II.

Additional settings enabled for TPMS system with a borrowed gray market PIWIS. My 2006 C2S did not come with the TPM option. The hardest part of the retrofit was manually running wires as the wires were not in the front and rear main harnesses in my car. Then it needed programming with PIWIS to activate.

The biggest difference with the track tire settings is you define the target pressures. The other settings are predefined base on summer vs winter, 18 vs 19, partial vs full load. Not positive but I think the size option was also enabled.

The “Track Tire” is the special setting. There is an option in car diagnostic scanner PIWIS to rename it to whatever you want. My OCD struggled with “Track Tyre” to match the other settings or “Track Tire” as it’s properly spelled where I live. I settled on the latter
