VXDIAG GM Win7 32bit Setup Review for GMC Sierra
You will find no cheaper alternative compatible with Tech2Win. Rest assured, if you install it exactly as described below you will find success – in fact, I just completed an automatic ABS bleed today with my GMC Sierra 2500HD!
Disclaimer:
As indicated by others, viruses and hidden software may lurk
in the required files. However, my own scan with Kapersky did not flag any.
Regardless, it is recommended to perform a fresh OS install on spare/burner PC
for three reasons:
1) No personal files or info to worry about
2) Windows
7 Professional 32-Bit is required. If you don't already have it, you will need
to get it and perform a fresh install. There are many documented failures from
attempting to use Windows 10, Win 7 64-bit, etc -I prefer Win7.
3) Lastly if
you think you can get away with running Windows 7 Pro 32-bit inside a Virtual
Machine, think again – Tech2Win will crash while establishing vehicle connection
(ask me how I know).
Okay, on to the guide…
1) Perform fresh install of Windows 7 Professional 32-bit (x86).
2)
Install drivers on your machine and all that good stuff.
3) Fully update
windows via Windows Updates (skipping this step may result in cryptic "missing
.dll"
errors during install).
4) Install Microsoft Visual C++
Redistributable 2010 to avoid more .dll errors.
5) From VXdiagshop.com, download the latest
versions of the following (do NOT use the USB key):
-VX Manager
-VXDIAG GM
GDS2
-VXDIAG GM Tech2Win
6) Unzip/extract as necessary. Inside the
Tech2Win folder, run AutoInstall.exe.
7) Inside the GDS2 folder, run
AutoInstall.exe. Expect long wait times. Note that GDS2 may not strictly be
required for Tech2Win but I installed it anyways.
8) Install VX Manager –
select PassThru & GM.
9) Plug in VCX
Nano GM. Windows will automatically find and install the USB driver as long
as step (8) has
been completed
10) Launch VX Manager. VCX Nano should now
be recognized. If not, unplug and re-plug back in, restart VX manager, restart
the computer, etc. It will show up eventually. Note that an OBD connection is
not required at this time.
11) Go to Diagnostic tab at top. Double click "GM
GDS2/T2W" and hit Install. Do the same to PassThru if it doesn't already have a
green checkmark.
12) Plug in to your vehicle.
13) Launch Tech2Win with VX
Manager still open in the background. Tech2Win It should prompt you to select
your communication tool in a popup window – pick GM MDI (not MDI 2). It should
then pause and prompt you again, this time with one option – a string of numbers
and "USB". If it does not prompt twice, close Tech2Win and try again.
14) Hit
OK at the second prompt. That's it – Tech2 emulation is running and you should
be able to communicate with your vehicle.
I've had fairly good luck pulling data and performing special functions with this since I got it working.
Good luck to you – hope the guide was helpful.
VXDIAG 2014 GMC Sierra ECM Programming Review
January 2023 new user review of vxdiag vcx nano for gm.
Worked great for GM SPS / Techline Connect programming.
This little device saved me a bundle. I had a job replacing a 6L80E transmission in a 2014 GMC Sierra. Instructions that came with the reman transmission stated the TCM/ECM needed to be updated together with most recent calibration and suggested towing the vehicle to the dealer. A tow plus dealer programming charge would have been several hundred at the very least. No thanks. Did a bit of research and a lot of folks recommended this little jewel.
It was very easy– install VX Manager, and choose the "J2534 Pass-thru driver" only. For SPS programming, you don't want all the other stuff. No viruses were detected when installing just that feature. I used a Windows 11 Pro 64 bit desktop computer. After VX Manager is installed, it will show you the device status, and you can update the VCX Nano firmware if you wish.
Once GM Techline Connect was installed, it recognized the VCX Nano right away and it was one of the module options when I got into the SPS programming. Paid GM $45 plus tax for the 2-year VIN subscription, and away it went. Updated the ECM/TCM like I was supposed to and all other modules that had fixes/updates. It performed flawlessly and truck / new transmission works great.
I can't comment on the GDS2 / Tech2 functionality of this unit, as I have an expensive scanner that does everything but J2534 Pass-thru. I might play with it someday, but I bought this purely for SPS programming and it was easy. It was also my first time using GM SPS/techline or programming a GM module if that says anything.
VXDIAG Solve GM Volt Gen1 "Reduced Propulsion Power" Error
Vehicle: GM Volt 2012 or other Gen1 models
Symptoms:
I experience the "reduced propulsion power (PPP)" message if I make a stop after switching to the ice on my way home.
Solution:
The message that required the update was
"service high voltage charging system". The range change was instant,
immediately following the update。
To enable hardware replacement, the Hybrid Powertrain Control Module 2 can be placed into a fast learn mode with the scan tool.
Here is the fix for this problem. ( Gen 1 Volt )
Purchase a used HPCM2
module from Ebay or an auto wrecker the same year as your Volt.
You can use another year Volt providing the used HPCM2 module has the same part number as stamped on your existing HPCM2 module label.
Next, purchase a vxdiag vcx nano programmer from the following web site:
https://www.vxdiagshop.com/wholesale/vxdiag-vcx-nano-for-gm-opel.html
Download the free software to run the VXDiag programmer into your laptop running Windows.
Disconnect your 12 volt battery, ( in the trunk compartment ) and swap in the used HPCM2 module ( module is located under the passenger front seat ) it is easier to remove the 2 torx bolts and lift the seat out of the way to swap the HCPM2 module out.
Reconnect the 12 volt battery. Power up your Volt. Next plug in the VXDiag programmer into your OBD2 port ( under the steering wheel ), run the downloaded program ( from VXDIAGSHOP website ) and "reset" the HCPM2 module in the menu. ( You need to scroll down the various menus to find this "reset" option )
Once you reset the HCPM2 module, turn the Volt off and back on again. Now charge your Volt. Your battery range will come back to the original 10.3kwh ( or whatever it was before the GM dealership HPCM2 firmware update ) per full charge range.
This method works 100% because I successfully performed this on my 2012 Chevy Volt car after a GM dealership reprogrammed my HCPM2 module and subsequently I lost 1.2kwh per full charge. ( 9.1kwh ).
VXDIAG Tech2win Opel 2009 No Cummunication Solution
Problem:
I have bought a vxdiag Vcx nano for Gm, i cannot set the communication to car with them. It says no communication with all modules. Car is a Opel Corsa D 1.3 diesel 2009. I'm running in windows 7 64bit Os if it's matters. All drivers and firmware are up to date.
Answer:
vcx nano gm tech2win won't do Open or Saab. Missing proper bin files.
