First Claim
Patent Images
1. A scan tool external to a vehicle, comprising:
- a data processor configured to process data;
a data port configured to couple to, and receive diagnostic information from, an on-board computer of the vehicle;
a network interface configured to couple to a data transmission network; and
a data storage device storing instructions that, upon execution by the data processor, control the diagnostic device to;
generate a search query according to the received diagnostic information;
access pre-stored information identifying multiple data sources;
using the search query, initiate a data search on the multiple data sources for information related to the received diagnostic information, wherein the multiple data sources couple to the scan tool via the data transmission network;
receive a result of data search returned by the multiple data sources; and
present the result of data search via a user interface.
