What is OBD-II?
“OBD” is a reference to “On Board Diagnostics,” and OBD-II (often abbreviated to OBD2) is the second generation of OBD technology. The vehicle’s computers track data from various components and monitor them for abnormalities. If a problem does arise, it’s stored on the computer as a diagnostic trouble code. It can trigger the check engine light on your dashboard. To access this information, all gasoline-powered vehicles since 1996 and all diesel vehicles since 2008 have an OBD2 port. It’s accessible without tools and features an identical design across all makes.
What Is An OBD2 Scanner?
OBD2 scanner ports were made standard on all domestic vehicles in 1996 following the federal government’s seeking to reduce vehicle emissions. They connect to a 16-pin connector. It is usually located under the steering column.
Developed by the California Air Resources Board (CARB), an OBD2 scanner interacts with your car’s computer system to detect error codes, run emission tests, and monitor specific information like the engine’s temperature. If your car’s computer detects an error, it will light up the check engine indicator. However, it is necessary to use an OBD2 scanner is required to identify the cause.
An OBD2 scan tool will show you a trouble code after scanning the troubled car. You’ll need to find the trouble code in an owner’s manual or on the internet. Most modern OBD2 scan tools will translate error codes automatically to make searching easier for mechanicians.
