WiFi版本VXDIAG VCX NANO用于GM

For DIYers who really understand car repair and diagnostics, this is an awesome aftermarket tool. It's way more than just a basic code reader.

You'll still need to buy an ACDelco subscription to unlock full functionality, but it works with GM's GDS system.

After watching some YouTube videos and doing some research, I found out that you need access to MDI2 and GDS2 to reset the car. There's a function to reset the Security HV DTC, and you have to run it to get the car moving. Otherwise, even if everything is fixed, you'll still have shifting issues.

That's when I found the VXDIAG device and tried it, and it worked great!

Before purchasing this product, I was drawn to VXDIAG website because of the many positive reviews shared by others. I would like to share my experience fixing some issues on my 2019 Chevy Bolt EV. I bought the car as a salvage vehicle, and initially, I ran into several problems. It wouldn't start, I couldn't get into service mode, and the key wouldn't reprogram.

Here is what happened:
At first, the car didn't have a 12V battery, and the voltage was only 3V. After replacing the battery, the dashboard lit up, and I could control the radio and the door locks with physical buttons, but the key wasn't responding. I kept getting the error message saying no remote key detected. I tried manually locking and unlocking the doors to reset the key's anti-theft system, but it didn't work because it was the wrong key. Also, I couldn't get the car into service mode, which is crucial for reprogramming the key.

I decided to use the VXDIAG VCX Nano and GDS2 software. Initially, it went smoothly. I cleared several fault codes. However, I still couldn't get the car into service mode no matter what I tried. I followed online advice, such as holding the start button without pressing the brake for 10 seconds, but nothing worked.

The most frustrating part came when I tried using the software from the ACDelco website. It wouldn't open because of a Java compatibility issue, which I figured out later. It wasn't the fault of the device. Eventually, I managed to run GDS2 locally, which allowed me to read some fault codes, but many modules still wouldn't communicate. I got stuck on two DTCs:

P0603: Brake Boost Control Module, Long-term Memory Reset
B3205: Body Control Module, Driver Window Motor Not Learned or Calibrated
After several days of troubleshooting, I finally found a solution. I used the door panel to manually operate the lock mechanism, which triggered a reset of the anti-theft system. However, the security system activated, and the horn started honking, so I had to disconnect the battery and temporarily stop the process.

After more adjustments, I uninstalled and reinstalled Java, which allowed me to run SPS and start the key learning process. This time, the car finally came back to life! The wipers worked, I could control the windows, and the brake lights turned on. Although programming still didn't succeed, I felt like I was getting closer.

Finally, the OEM replacement key arrived. That was the real issue. Once I had the correct key, I successfully programmed it via SPS. Now the car starts, charges normally, and I can enter service mode and clear fault codes. Great job, VXDIAG!

For anyone else facing similar problems, my advice is to stay patient and persistent. Make sure to use the right tools. I highly recommend the VXDIAG VCX Nano and purchasing from the official VXDIAG website. I have a lot of online shopping experience, and sometimes price is not the only consideration. Also, DO NOT skimp on OEM parts, especially the key. It will save you a lot of time and hassle.

I hope my experience helps others, and thanks to VXDIAG for their support during this process!

I bought the VXDIAG VCX Nano for my VF Holden Commodore about a month ago, and I have to say, the device is fantastic. I got it from the official website, and while the setup was a bit tricky at first, I havve got enough experience with repairs to get everything up and running smoothly.

I used it mainly to fix a few issues, like a faulty injector, the airbag light, and the steering column lock. One of the first things I did was update the Mylink system firmware, which was super easy. I just downloaded the update through the TIS2WEB Java interface, put it on a USB drive, plugged it into the Mylink system, and the update went through without any problems. Then I quickly reprogrammed the radio module with just a few clicks.

I'm running it on Windows 10, and GDS2 worked perfectly fine. Tech 2 does NOT work on GDS2 vehicles, but that wasnot an issue for me. Everything worked as expected - I did EPB calibration, reset the steering angle, and controlled BCM functions like unlocking the trunk and locking/unlocking doors. I have seen the brake bleed option but haven't tried it yet.

For reprogramming, you do need a TDS subscription, but once that's taken care of, everything runs smoothly. The device works great on both Windows 7 and Windows 10, and there's no need for a virtual machine, it just connects to the car with no issues.

At first, I didn‘t realize Tech2Win only works on Windows 7 32-bit. After looking it up, I found out that’s actually the case. Since the software and the cars are pretty old, they only run on Win7. So, I switched to another system for diagnostics, and luckily, it worked fine.
