If I am correct, each car has different codes. The OBD-II is just a standard system for obtaining these codes. Ford, GM, and other makers use different versions of this system, but can all be read by the same device if it's programmed correctly. The mechanic has to have the codes for each car, because the system only is a standard for retrieving the codes.
