Experience with install VXdiag VCX Nano GM with PCM Hammer

After receiving VXDIAG VCX Nano for GM Opel, I’ve installed PCM Hammer on a laptop running Windows 7 Ultimate and I’ve plugged in the VCX Nano to the USB port and Windows reported that the device driver was installed.


When I run PCM Hammer, I then clicked – SELECT DEVICE – Then – J2534, under the J2534 Device List nothing is listed. What to do next?

I was suggested: to install VX Manager and during the installation, check the box to install the J2534 driver with it. After it’s installed it will work. You do not need to have VX Manager open when using PCM Hammer. Don’t bother with the cd that comes with it. Get the software from vxdiagshop.com




I downloaded and installed the software. I selected J2534 pass through.
When I bring up VX Manager in device settings it tells me that I need to update the license.
I also get the same message Update license when I launch PCM Hammer.
I tried the Update License ICON – but I get UPDATE FAILED: Error 0. Try Again.


Finally, !!!! SUCCESS !!!!

To update the license it seems that the firmware had to be updated first.

In VX Manager – Device Tab

– Select Update Firmware.

When the update was finished, the program tried to update the license and failed.

I then selected – Update License.

The license was successfully updated.

So far I have been able to read a 1MB PCM, read time was 5 minutes. Writing to the PCM was successful too. I was able to clone a PCM in under 2 minutes.
