Thats something different. Apparently GM media and GM engineering use the same acronym, but for different things.....I guess they dont communicate much lol.Gatecrasher wrote:You're not wrong about the lockouts, but that's not what DVT means.

Check out the video at the bottom of the page. Skip to 16:30. They show the DVT process.“The first thing that happens is alignment. The car is driven over an alignment pit with operators under the car doing the work with about 30 individual checks. The next step is Dynamic Vehicle Test (‘DVT’). Over 8,000 checks are done in DVT. The car will check a lot of things itself. In here we communicate with the vehicle and are looking to find things like are the antennas working properly for OnStar.”
GM engineering, their "DVT" is Diagnostic Vehicle Tests. And its what I described, secret elevated permissions for mode AE crap that doesnt have the protections that are otherwise implemented in GDS to prevent dealer techs from doing something harmful. The engineering DVT stuff (device control) is only used by the engineers during development.
In GM media, their "DVT" is "dynamic vehicle test", and its just a catch-all term for what they do to every car as it rolls off the assembly line.
