Security gateway adapter

A method for establishing a bi-directional communication session between a diagnostic scan tool and a security gateway of a vehicle over a security gateway adapter, the method comprising:

• connecting the security gateway adapter to a data link connector of the vehicle;
• retrieving an access credential from a remote server;
• presenting the access credential to the security gateway;
• opening a validated communication link session with the security gateway;
• maintaining, by the security gateway adapter, the validated communication link session with the security gateway in an open state to permit bidirectional communications between the diagnostic scan tool and one or more electronic control units through the validated communication link session without the diagnostic scan tool presenting the access credential to the security gateway;
• receiving scan tool commands and data from the diagnostic scan tool;
• transmitting the scan tool commands and data to the electronic control units of the vehicle over the validated communication link session with the security gateway, the electronic control units being connectible to the security gateway adapter indirectly through the security gateway;
• receiving vehicle data from the electronic control units of the vehicle over the validated communication link session with the security gateway;
• and
• transmitting the vehicle data to the diagnostic scan tool.

A vehicle security gateway auxiliary access system, comprising:

• a security gateway adapter connectible to a diagnostic scan tool and a vehicle network interface of a vehicle, the security gateway adapter including a wireless communications module;
• and
• a computing device connectible to the wireless communications module of the security gateway adapter over a first modality and a second modality, the computing device further being connectible to a remote server to retrieve an access credential provided thereby in response to a presentation of an authentication request including a security authorization token retrieved from the vehicle;
• wherein the access credential is presented by the security gateway adapter to the security gateway to establish and maintain a validated communication link session, the validated communication link session being maintained in an open state by the security gateway adapter to permit bidirectional communications between the diagnostic scan tool and electronic control units through the validated communication link session;
• wherein scan tool commands and data from the diagnostic scan tool are relayed to the electronic control units behind the security gateway over the validated communication link session, and vehicle data from one or more of the electronic control units is relayed to the diagnostic scan tool over the validated communication link session.

An article of manufacture comprising a non-transitory program storage medium readable by a computing device, the medium tangibly embodying one or more programs of instructions executable by the device to perform a method for establishing a bi-directional communication session between a diagnostic scan tool and a security gateway of a vehicle over a security gateway adapter, the method comprising:

• establishing a first local area communication link to the security gateway adapter;
• connecting to a remote server over a remote communication link;
• retrieving an access credential from the remote server over the remote communication link in response to an authentication request received from the security gateway adapter over the local area communication link, the authentication request including a security authorization token specific to the security gateway and the access credential corresponding to the security authorization token;
• and
• transmitting the access credential to the security gateway adapter over the first local area communication link for presentation by the security gateway adapter to the security gateway to establish and maintain a validated communication link session with the security gateway, the validated communication link session being maintained in an open state by the security gateway adapter to permit bidirectional communications between the diagnostic scan tool and one or more electronic control units of the vehicle through the validated communication link session.
