I used the OBDxpro GT. 140$ dongle. I newer laptop rust can access gm acdelco website for the software. it's pretty picky about pc specs. my older laptop I use for hptuners wouldn't do it.

and then it's 40$ per vin number for 2 years of access to the updates.

or you can try towing it to a dealership.
