How to Use a Scan Tool on a Car

Learning how to use a scan tool on a car can empower you to diagnose and sometimes even fix car problems yourself. This guide provides a comprehensive overview of how to use a scan tool, from understanding the basics to interpreting the data you receive.

Understanding Car Scan Tools

Car scan tools, also known as OBD2 scanners, are essential tools for diagnosing car troubles. They communicate with your car’s computer, retrieving diagnostic trouble codes (DTCs) that indicate potential issues. These codes are standardized, meaning a “P0301” code will signify a misfire in cylinder 1 regardless of the car make or model (within certain year ranges).
