Default Reading H1 ODB codes

Dad has an H1 Alpha giving a check engine light. The dealership he bought in from in the Dallas area isn't GM anymore and will no longer service the truck. Can a GM dealership or general mechanic check the code on a Hummer? I'm hoping we can at least determine what the code is in Dallas. The truck has pretty low mileage and doesn't get driven a lot, it has no other symptoms beyond the light.
