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.

Abstract: A physical and electrical support device for use in connecting a handheld electronic unit to a port on a vehicle includes a plug configured to be selectively engageable with the port on the vehicle. The plug includes at least one plug electrical contact disposable in electrical connection with the port electrical contact when the plug is engaged with the port. A mounting body is moveably coupled to the plug and is configured to have a first form factor. The mounting body includes a mount electrical contact in electrical communication with the at least one plug electrical contact. A handheld electronic unit is configured to be engageable with the mounting body. The handheld electronic device includes a portion thereof having a second form factor complementary to the first form factor to facilitate engagement between the handheld electronic unit and the mounting body.
