Chevy Volt VXDIAG GDS2 SPS Programming Setup Tips

With SPS you can update the ecu software ( gm calls it calibration). Other tweaks can be done with gds2 offline.  The following is what you can do to get Chevy Volt to work with VXDIAG VCX Nano GM via SPS:

Note:

Only have to install PASSTHRU when installing VX Manager app if all you are doing is SPS programming…you don’t need to open the VX Manager app to use SPS.
It is a good idea to check if your VCX Nano is running the latest firmware using the VX Manager app though.

Subscribe ACDelco Module upgrade software (acdelcotds subscriptions)

You have to get GMs J2534 Wrapper to install successfully. I did this by executing old legacy IE in administrator mode to logon to ACDelco TDS (right click select ‘run as administrator’)
You only have to do this once. After the J2543 Wrapper is installed you can run java normally not as administrator

After you launch SPS java select run above

Again, select run at the above dialog box

You don’t need MIDI or Tech2 drivers to do any SPS programming…just the J2534 Wrapper as shown above then hit Install button

If java was executed as administrator, you will get the above showing J2534 Wrapper was installed successfully…if you didn’t run as administrator it will fail

Now you should be able to select the J2543 Tool in order to push firmware onto your volt..SPS should now be able to read VIN w/o issue!

VCX allows programming and is more like what the dealer uses.
