Abstract
A multi-point serial link protocol, such as USB, is used to transfer vehicle diagnostic information back and forth between vehicle diagnostic sensors and a host computer. Multiple distinct vehicle servicing applications may be added to or removed from the service bay without requiring substantial software changes or revisions. The amount of vehicle diagnostic hardware is also minimized. The multi-point serial link may originate in the vehicle's on-board computer, allowing the vehicle itself to function as a data hub for the diagnostic automotive service sensors.
