Understanding OBD2 and How it Works
OBD stands for On-Board Diagnostics. OBD2, specifically, refers to the standardized system used in most gasoline vehicles manufactured since 1996 and diesel vehicles since 2008. The OBD2 system monitors various vehicle components, detecting malfunctions and storing corresponding diagnostic trouble codes (DTCs) in the car’s computer.
The OBD2 port, a 16-pin connector usually located under the dashboard on the driver’s side, allows access to this information. An OBD2 scanner connects to this port, retrieves the DTCs, and displays them on its screen or a connected device. Once the problem is fixed, using the best OBD2 scanner clear codes function allows you to erase the codes and reset the check engine light.
