For car enthusiasts and everyday drivers alike, understanding your vehicle’s health is becoming increasingly important. Gone are the days when a simple wrench and some know-how were all you needed to keep your car running smoothly. Modern vehicles are complex machines, heavily reliant on onboard computers and sensors. This is where OBD2 scanners come into play, acting as a vital bridge between you and your car’s diagnostic system. In 2020, the market was flooded with options, making it challenging to choose the right tool. This guide will delve into the best OBD2 scanner tools available in 2020, helping you make an informed decision for your DIY automotive diagnostics needs.
Choosing the right OBD2 scanner can save you both time and money by allowing you to diagnose issues from the comfort of your garage. Instead of immediately rushing to a mechanic for every check engine light, you can use an OBD2 scanner to read diagnostic trouble codes (DTCs), understand what’s wrong, and decide on the best course of action. Whether you’re a seasoned DIY mechanic or just starting to learn about car maintenance, having a reliable OBD2 scanner in your toolkit is a smart investment.
Understanding OBD2 Scanners and Their Importance
OBD2, or On-Board Diagnostics II, is a standardized system implemented in most vehicles manufactured after 1996. It monitors various systems within your car, from the engine and transmission to emissions and more. When something goes wrong, the system generates diagnostic trouble codes, which are essentially error messages that pinpoint the problem area. An OBD2 scanner is the tool that allows you to access and interpret these codes.
In 2020, the landscape of OBD2 scanners was diverse, ranging from basic handheld code readers to sophisticated Bluetooth and Wi-Fi enabled devices that pair with smartphone apps. The core function of all these tools is to read DTCs, but more advanced scanners offer a wealth of additional features such as:
- Live Data Streaming: View real-time data from your vehicle’s sensors, such as engine temperature, RPM, and sensor readings. This is invaluable for diagnosing intermittent issues or monitoring performance.
- Freeze Frame Data: Capture a snapshot of sensor data at the moment a DTC is triggered. This helps in understanding the conditions under which the fault occurred.
- Service Resets: Some scanners allow you to reset service lights, oil change reminders, and even perform basic maintenance procedures like resetting the electronic parking brake for brake pad replacement.
- Advanced Diagnostics: Higher-end scanners can access manufacturer-specific codes and perform bidirectional controls, allowing for more in-depth diagnostics and testing of individual components.

Types of OBD2 Scanner Tools in 2020
The OBD2 scanner market in 2020 offered a variety of tools to suit different needs and budgets. Here’s a look at the main categories:
-
Basic Handheld OBD2 Code Readers: These are the most affordable and straightforward options. They typically read and clear DTCs and may offer basic freeze frame data. Ideal for users who primarily need to address check engine lights and perform simple diagnostics. They are unidirectional, meaning they primarily receive data and do not send commands to the vehicle.
-
Bluetooth and Wi-Fi OBD2 Scanners: These scanners pair wirelessly with smartphones or tablets via Bluetooth or Wi-Fi. They rely on OBD2 apps (like OBD Fusion, mentioned in the original text) to display data and provide a user interface. These systems often offer a good balance of features and affordability. They can provide live data, enhanced diagnostics (depending on the app), and data logging capabilities. The convenience of using your smartphone as a display makes them very popular.
-
Professional-Grade Handheld Scanners: These are more expensive, robust tools designed for professional mechanics and serious DIYers. They offer comprehensive diagnostics, bidirectional controls, advanced service functions, and often come with larger color screens and dedicated software. They can access a wider range of vehicle systems and manufacturer-specific codes. While pricier, they provide deeper diagnostic capabilities and often eliminate the need for subscription fees for basic functionality.
-
PC-Based OBD2 Scanner Interfaces: These systems involve a hardware interface that connects your car to a laptop or desktop computer. They leverage powerful PC-based software for in-depth diagnostics, data analysis, and customization. Often favored by advanced users who need extensive logging, graphing, and analysis capabilities.

Key Features to Consider When Choosing an OBD2 Scanner in 2020
When selecting an OBD2 scanner in 2020, several key features should be considered to ensure you choose a tool that meets your needs:
- Compatibility: Ensure the scanner is compatible with your vehicle’s make and model. While OBD2 is standardized, some scanners may have limited compatibility with certain manufacturers or specific vehicle systems.
- Functionality: Determine the level of functionality you require. Do you just need basic code reading and clearing, or do you need live data, advanced diagnostics, and service resets? Choose a scanner that offers the features you’ll actually use.
- Ease of Use: Consider the user interface and ease of operation. For handheld scanners, look for clear menus and easy navigation. For app-based scanners, evaluate the app’s user-friendliness and features.
- Update Capability: Software updates are important to ensure compatibility with newer vehicles and to access the latest features and bug fixes. Check if the scanner offers free or affordable updates.
- Build Quality and Durability: If you plan to use the scanner frequently or in a demanding environment, consider the build quality and durability of the device.
- Price: OBD2 scanners range in price from under $50 for basic code readers to several hundred or even thousands of dollars for professional-grade tools. Set a budget and choose a scanner that offers the best value within your price range.
Top OBD2 Scanner Tool Considerations in 2020
While specific “top” models of 2020 might be debated, some general considerations and types of tools stood out in that year:
- For Basic DIY Use: Simple handheld code readers from reputable brands offered excellent value for basic check engine light diagnostics. Brands like Autel, Innova, and BlueDriver (for app-based scanning) were popular choices for their reliability and user-friendliness.
- For App-Based Diagnostics: Bluetooth OBD2 adapters paired with apps like OBD Fusion, Torque Pro, and Carista provided a powerful and versatile diagnostic solution at a reasonable cost. These combinations offered live data, customizable dashboards, and enhanced diagnostics depending on the app and adapter capabilities. Choosing a quality Bluetooth adapter with good connectivity was crucial for a smooth experience.
- For Advanced DIY and Semi-Professional Use: Mid-range handheld scanners from brands like Launch and Foxwell offered a step up in functionality, providing bidirectional controls, service resets, and deeper system diagnostics. These tools bridged the gap between basic DIY and professional-level equipment.
