Problem:
I had a file verification failed error when installing SGM RDS driver for the vxdiag vcx nango gm scanner. Any idea what’s going on?
Vxdiagshop.com solution:
You don’t need to install SGM RDS driver.
RDS is for Chinese cars.
Just install Passthru and GDS2/T2W drivers.
If still had this error, install GM VCI driver in “Tech2win” software folder.
