Field notes
The homepage organizes the service into Codes, Tools, Specs, Blog, and About, with a single “Look up” action and a set of linked popular codes. Its examples span emissions, ignition, fuel/air, cooling, and EVAP faults; each visible entry pairs a code with a category and plain-language description. The page attributes its broader vehicle-information material to public NHTSA data, though those interfaces are not visible in the extract.
