Abstract
A method and apparatus for communicating between a host and a motor vehicle, the motor vehicle including an on board computer system having a bus for communicating with a plurality of motor vehicle systems. The apparatus includes an electronic tag having a transceiver for transmitting data to and receiving data from the host, a memory for storing bus requests and bus response data, a decoder for decoding requests from the host, a bus interface for reading data from and writing data to the bus, a controller and a filter. The bus interface extracts responses from the bus responsive to requests from the host. The responses may be stored in the memory. The controller is responsive to write requests from the host to transfer data to the bus interface and responsive to read requests from the host to transfer data stored in memory back to the host. The filter is operable to filter responses received from the bus and includes a filter database. The filter database includes one or more screening parameters for screening responses received from the bus.
