Abstract
A vehicle anti-theft system includes programming vehicle identification numbers or a corresponding identifier value into a read-only memory portion of each computer on board the vehicle. The computers are all linked through a multiplex communication system that has a monitoring port. The monitoring port facilitates coupling an external device to the multiplex communication link. The external monitoring device is used to determine the contents of the read only memory portion on each component to determine whether any of the components were stolen from another vehicle, for example.
