OBD-II Port
The standardized diagnostic interface used to connect scan tools to vehicle ECUs.
The OBD-II port, introduced globally in the late 1990s, allows access to engine and emissions data through standardized protocols. It's typically located beneath the dashboard. Mechanics use it to retrieve trouble codes, monitor real-time data, and reset systems. Maintaining a clean and undamaged port ensures reliable communication with diagnostic devices. OBD-II technology has revolutionized automotive diagnostics, enabling faster repairs and better emission compliance.
