How Does a Universal Car Fault Diagnostic Code Reader OBD2 Work?

Your car’s computer system continuously monitors various sensors and components. When a problem is detected, it generates a specific code stored in the computer’s memory. A universal car fault diagnostic code reader OBD2 connects to this system through the standardized OBD2 port, typically located under the dashboard on the driver’s side.

Once connected, the scanner retrieves these codes and displays them on its screen. These codes, often a combination of letters and numbers, correspond to specific issues within your vehicle.
