Abstract
Provided is a method of receiving data from a vehicle onboard computer. The onboard computer is configured to transmit vehicle identification data in response to receipt of an identification request, which is transmitted in a basic communication protocol. The onboard computer is further configured to transmit private operational data in response to receipt of a private data request. The private data request is transmitted in a diagnostic protocol. The method includes connecting a scan tool to the onboard computer, and polling the onboard computer to identify the basic communication protocol. The identification request is then transmitted to the onboard computer. Vehicle identification data is subsequently received from the onboard computer. A protocol database having a plurality of diagnostic protocols is then accessed. Each diagnostic protocol is associated with respective vehicle identification data. The diagnostic protocol is then determined based on the received vehicle identification data.
