Imagine this: you’re driving down the road, enjoying a beautiful sunset, when suddenly, your car starts acting up. The engine light flashes on, and you’re left wondering what’s wrong. You know you need to take it to a mechanic, but first, you want to try to understand the problem yourself. This is where an OBD2 scan tool comes in.
An OBD2 scan tool is a device that plugs into your car’s diagnostic port (usually located under the dashboard) and allows you to read and interpret diagnostic codes. These codes can tell you what’s wrong with your car, helping you diagnose the issue and potentially save money on costly repairs.
What are OBD2 Scan Tools?
OBD2 (On-Board Diagnostics 2) is a standardized system for automotive diagnostics that was first introduced in 1996 for gasoline-powered vehicles and 2008 for diesel-powered vehicles in the United States. Every car sold in the United States after these years must be equipped with an OBD2 system. The OBD2 system monitors various components in your car, including the engine, transmission, and emissions control systems. If any of these components malfunction, the system stores a diagnostic code, which can be read by an OBD2 scan tool.
Different Types of OBD2 Scan Tools
There are many different types of OBD2 scan tools on the market, ranging in price, features, and functionality. Here’s a breakdown of the most popular types:
Basic OBD2 Scan Tools

These are the most affordable and basic type of scan tools. They are typically small and handheld and can only read and clear diagnostic codes. If you are looking for a basic tool to help you diagnose simple issues, a basic OBD2 scan tool is a good option. Some of these tools include a built-in database with information on each code, so you can easily understand what they mean.
Enhanced OBD2 Scan Tools

Enhanced OBD2 scan tools have a wider range of features than basic tools. They can often read and clear diagnostic codes, view live data streams, and retrieve freeze frame data, which helps pinpoint the exact conditions that led to a fault code. These tools can also be used to view sensor readings, giving you a more in-depth understanding of your car’s performance.
Professional-Grade OBD2 Scan Tools

These tools are designed for professional mechanics and often have the most advanced features and functionality. They can perform a wide range of diagnostic functions, including reading and clearing codes, viewing live data, performing bi-directional control, and even programming and reprogramming vehicle control modules (ECMs).
Dealer-Level Scan Tools
These tools are the most advanced type of scan tool and are often used by car dealerships and professional mechanics. They can perform all of the functions of professional-grade scan tools and can also access information that is not available through other types of tools. Dealer-level scan tools are typically very expensive, but they can be essential for diagnosing and repairing complex problems.
Q: What are some common OBD2 scan tool brands?
A: Some popular brands include Actron, BlueDriver, Launch, Autel, and Ancel.
Which OBD2 Scan Tool is Right for You?
The best OBD2 scan tool for you will depend on your needs and budget. If you’re looking for a basic tool to help you diagnose simple issues, a basic OBD2 scan tool is a good option. If you’re a more experienced DIY mechanic or are looking to diagnose and repair more complex problems, an enhanced or professional-grade scan tool may be a better choice.
Q: Can I use an OBD2 scan tool to reset the “check engine” light?
A: Yes, most OBD2 scan tools can clear diagnostic codes, which will often reset the “check engine” light. However, keep in mind that clearing the code doesn’t necessarily fix the underlying problem. If the problem persists, the light will likely come back on.
Q: What types of information can an OBD2 scan tool provide?
A: An OBD2 scan tool can provide a wide range of information about your car, including:
- Diagnostic codes: These codes can tell you what’s wrong with your car.
- Live data: This is information that is being captured in real-time, such as engine RPM, fuel pressure, and air flow.
- Freeze frame data: This information records the conditions of your car at the time a diagnostic code was set.
- Sensor readings: This information shows the current readings of various sensors in your car.
- Vehicle identification information: This includes the vehicle identification number (VIN), engine code, and other identifying information.
What Are Some Additional Tips?
- Always consult with a qualified mechanic before attempting any repairs.
- Make sure the scan tool is compatible with your car.
- Follow the instructions carefully when using the scan tool.
