Security gateway adapter

Abstract

An adapter device bidirectionally interconnects a diagnostic scan tool to an electronic control unit through the security gateway of a vehicle. A scan tool interface is connectable to the diagnostic scan tool, and a vehicle network interface is connectable to a data link connector of the vehicle. A wireless communications module is connectable to a remote server. A security gateway bypass opens and maintains a validated communication link session with the security gateway through the vehicle interface based upon a presentation of an access credential thereto received from the remote server in response to an authentication request with a security authorization token. A data transfer and control processor is receptive to scan tool commands and data from the diagnostic scan tool through the scan tool interface, and to vehicle data from the electronic control unit through the vehicle network interface.
