ABSTRACT:
An apparatus and method for monitoring the status of a multiple part vehicle. An apparatus according to the invention comprises a tag for placement on a second part of the vehicle. The tag communicates a unique ID code to an interface unit on the first part of the vehicle. The interface unit detects the presence of a valid ID code, and in response, provides an indication that the second part of the vehicle is connected. A transmitter provides data indicative of the connect/disconnect status of the vehicle to a central station. Vehicle position data may also be provided to the central station.
