Recently, a customer shared their experience of using the VXDIAG VCX Nano device for GMC Tahoe SPS2 online programming. In this article, he will explain in detail how to use VXDIAG VCX Nano with Techline Connect for GMC Tahoe programming based on their experience.
Here is the customer's personal account of their experience:
I originally owned a Tech2 diagnostic tool and tried countless times to use it as a pass-through to connect with GM’s SPS website, but I was unsuccessful. After doing some research, I discovered that GM had updated the SPS site, and Tech2 was no longer directly supported unless I contacted GM support. Typically, GM would provide a one-day pass for legacy SPS access.
While searching for an alternative, I came across references to using a VCI device (like an MDI clone) such as VXDIAG VCX Nano GM. I decided to purchase one from the official VXDIAG website.
Installation and Setup
First, I downloaded and installed VX Manager from the VXDIAG website and selected the GM option during installation (as shown in the picture). I used the default settings for installation. Before installing the diagnostic modules, I first installed the Techline Connect (TLC) suite from ACDelco TDS. Please note, you need an account, which costs $45 per VIN, to access the SPS2 services website.
After installing the TLC suite, I returned to the VX Manager application that had already been installed, ensured that the VCX Nano device was connected to my computer via the USB cable, and then proceeded to install the required tools under the "Diagnostics" tab.
Connection and Usage
After installing these applications, I logged back into the acdelcotds.com website, added my vehicle's VIN, and launched Techline Connect via the webpage. The SPS2 site was then able to recognize my VCX Nano GM device as a GM MDI device, which allowed communication with my vehicle systems. As shown in the picture below, the device is recognized as a J2534 Bosch MDI device.
Conclusion
By following these steps, I successfully connected the VXDIAG VCX Nano to the SPS2 website and completed the programming for my GMC Tahoe. For users like me who encountered issues with Tech2, the VXDIAG VCX Nano is an excellent alternative tool.
I hope my experience can help other vehicle owners and technicians who are facing similar problems.
