Problem:

One of our customers got the VXDIAG VCX FD unit without license and set up the vcx fd as a J2534 passthru for Techline Connect SPS2.

But he had no luck with SPS2 programming.

Error:

Solution:

To use VCX FD (or VCX SE/VCX NANO) with GM Techline Connect SPS2, you must have GM license activated.

You cannot use VCX FD as a J2534 device for SPS2 without GM license.
