From damaged modules to dead vehicles, you could cost yourself a lot of money. This isn't just the trucks, just general GM info to keep in mind.

Why would anyone swap a control module?

Yeah not really seeing the point of this. Why would you swap modules?

People do it all the time, testing stuff. Like trying to find a cluster problem, so they "borrow" a friends to test with.

As an auto tech it sucks when you are trying to find problems with certain modules. Most if them have to be programmed just so the vehicle starts.
