Understanding OBD2 Scanners and their Function
OBD2 (On-Board Diagnostics 2) is a standard communication protocol used in most vehicles manufactured after 1996. An OBD2 scanner is a device that plugs into your car’s diagnostic port (usually located under the dashboard) and allows you to communicate with the vehicle’s onboard computer. It reads diagnostic trouble codes (DTCs) that indicate potential issues with the engine, transmission, emissions system, and other components.
