It allows you to connect diagnostic devices, such as an OBD2 scanner, to your vehicle’s computer.Using this port, you can read diagnostic trouble codes (DTCs), monitor live data (such as engine RPM, coolant temperature, fuel efficiency), and identify problems with your car’s engine or emissions system. It’s commonly used to diagnose the cause behind a “Check Engine” ligh
