For any one looking for an awesome code scanner that not only reads normal ECM codes (P codes) but also B, C and U codes, I highly recommend the VXDiag that you can find on Amazon. It’s like a virtual Tech2! I recently had a Service ESC light on and instead of a $125+ dealer visit to read the code, I spent less than that on this tool instead.

It’s a module that plugs into your OBD2 port then has a USB connection to a laptop. They seller provides software and you use Tech2Win (software-based Tech2) to communicate through the module to your various systems. Worked well for what I needed - I was able to read my C0460 5A code and determine that my steering angle sensor was on the fritz. Reviews state it only works with 32-bit WinXP (lol) or Win 7, but it worked perfectly on my Win10 64-bit install on my MacBook Air (boot camp)

In summary, it’s a dirt cheap virtual Tech2 to scan and do anything a dealer can do, I highly recommend it

 

Got any screen shots/pictures of the device? Hard to verify your story without any proof.

 

I’ll be happy to add some, even a video, once I get home and use it again. I’d provide links to the device too but not sure if that’s allowed, amazon search for VXDiag GM and it’s the first one.

 

I also want to add that any programming related task like Radio relearn, crank relearn, Stage 1/2 flashing etc required a subscription to https://www.acdelcotds.com/subscriptions# which lets you purchase a 2 year $40 subscription to be able to utilize the programming capabilities.

My needs did not require this as I just wanted the ability to read any and all body, chassis, ABS and SRS airbag codes. Pics and videos coming tomorrow.

Once installed it shows up as a COM Port and a USB Serial Converter

 

Pretty interesting. Great video. Does it also do a throttle body relearn? If so, that could be a huge seeking point.

 

My experience with the VXDiag is with a Cruze and Volt. Both of the cars freaked out and did weird things flashing random lights on the dash and center stack when hooked up to VXdiag and produced a ton of U-codes. It was jacking up the CAN bus causing a bunch of issues with CAN messages (leading to the U-codes). The software it comes with is pirated, found in a virtual PC. I tried to make this setup work but it wasn't working out, the GDS software stopped working and then USB drivers had problems.

I returned the VXDiag and bought a used genuine MDI off ebay, works perfect using GM licensed software. I bought the 3-day license for GDS2, but they gave me 30 days so that is awesome.

 

Thanks! And I guess it can? It should be able to do everything a Tech2 can do. My purpose for purchasing it was to read codes that a normal scanner couldn’t read and it didn’t disappoint. I really can’t answer this question unless someone with Tech2 knowledge chimes in.

 

Yes I've seen this device sold in other ways, you may have gotten yours from obdii365 or alibaba I saw sales of this VXDiag that comes with weird software. I saw the listing where the software included is a WinXP VM that has the software pre-installed inside, this was not it - this was the software you can install on your own OS (physical or virtual).

you either had a jacked up VXDiag or funky software, mine performed flawlessly. Looks like YMMV but the amazon one ships prime and so it comes with a great return policy. Since this is a Cobalt forum I was posting my experience with the Tech2Win + VCX Nano combo, the included GDS2 did not support the older Cobalt so I can’t speak much of it. Sorry you had a strange experience with it.
