What is OBD2 and How Does a Diagnostic Scan Tool Work?
OBD2 stands for On-Board Diagnostics, generation two. It’s a standardized system that allows external devices, like OBD2 universal diagnostic scan tools, to access your vehicle’s computer system and retrieve diagnostic information. This system has been mandatory in all cars and light trucks sold in the United States since 1996.
A diagnostic scan tool acts as a bridge between you and your car’s computer. It plugs into the OBD2 port, usually located under the dashboard on the driver’s side, and allows you to:
- Read and clear fault codes: When something goes wrong with your car, the computer stores a fault code in its memory. A scan tool can read these codes and tell you what they mean.
- View live data: You can see real-time information from various sensors throughout your vehicle, such as engine speed, coolant temperature, and oxygen sensor readings.
- Run tests: Some scan tools allow you to run tests on specific components, like the ABS system or the oxygen sensors.
Why Do I Need a Diagnostic Scan Tool Can OBD2?
You might be thinking, “Do I really need a diagnostic scan tool?” The answer, in short, is yes. Here’s why:
- Save Time and Money: Instead of taking your car to a mechanic for every little issue, a scan tool can help you diagnose the problem yourself. This can save you both time and money on unnecessary trips to the repair shop.
- Empower Yourself: Understanding what’s going on with your car gives you a sense of control. You’ll be able to make informed decisions about repairs and maintenance.
- Prevent Major Issues: Regularly scanning your car for fault codes can help you catch small problems before they turn into big, expensive repairs.

- Basic Code Readers: These affordable tools can read and clear basic fault codes. They’re a good option for car owners who want to do some basic troubleshooting.
- Advanced Scan Tools: These tools offer more features, such as live data viewing, component testing, and access to manufacturer-specific codes.
- Professional Scan Tools: These high-end tools are designed for professional mechanics and offer the most comprehensive diagnostic capabilities.
When choosing a scan tool, consider your budget, your technical skills, and the features you need.
How to Use a Diagnostic Scan Tool: A Step-by-Step Guide
