OBD II (On Board Diagnostics Second Generation) is a system in your car that monitors how well the engine and other parts are working, and it can give you a warning if something goes wrong.
Standard on gasoline American Cars since 1996 and diesel since 1997 and initially implented as a way to monitor emissions, OBD has now evolved into a full fault reporting system for modern vehicles.
What is an OBD-II port?
The OBD-II port is a special plug in your car where mechanics can connect a scanner to check the car’s computer for any problems or errors.
Every modern car owner should have an OBD scanner because it allows you to quickly diagnose problems with your car, saving time and money on professional diagnostics, whilst maintaining your vehicle’s health by catching issues early.
