The days when OBD2 scanners were exclusive, expensive tools reserved only for mechanics are long gone. Today, these diagnostic devices are accessible and essential for every driver.
Having an OBD-II scanner in your car can help you quickly diagnose issues, potentially saving you from costly repairs and giving you peace of mind before consulting a professional. But with so many options available, how do you choose the right one?
In this article, we’ll guide you through the key factors to consider when selecting a car scanner and highlight the best OBD2 scanners of 2024.
What's the Difference Between Cheap and Expensive OBD2 Scanners
Cheap OBD2 scanners typically offer only the most basic functions, such as reading and clearing codes.
They may not provide additional data or features like live data streaming, bi-directional control, or compatibility with a wide range of vehicle systems.
These budget-friendly options are sufficient for basic diagnostics but may fall short for more complex issues.
Expensive OBD2 scanners are packed with advanced features that justify their higher cost.
These devices can perform comprehensive diagnostics, including the ability to test and troubleshoot various vehicle systems like the ABS, SRS, and transmission.
They support a wider range of vehicles and often include features like bi-directional controls, which allow users to actively test components such as actuators and relays.
Expensive scanners usually come with regular software updates to ensure they stay compatible with the latest vehicles.
For professionals or serious DIY enthusiasts, investing in a more expensive scanner can provide a significant return in terms of functionality and reliability.

Key Features to Consider When Choosing an OBD 2 Scanner
Selecting the right OBD 2 code scanner is not just about picking the first tool you come across; it’s about finding a device that meets your specific needs and offers the best value for your investment.
1. Compatibility
Compatibility is the cornerstone of any good OBD 2 scanner. Before making a purchase, it’s crucial to ensure that the scanner you choose is fully compatible with your vehicle.
While most OBD2 scanners work with vehicles manufactured after 1996 (when OBD2 became standardized), some advanced features might only be supported by certain makes and models.
If you own a European, Asian, or luxury vehicle, it’s important to verify that the scanner supports the specific protocols used by these cars.
High-end vehicles may use proprietary systems that require a more advanced scanner.
Some scanners are better equipped to handle hybrid or electric vehicles, which have different diagnostic needs compared to traditional gasoline-powered cars.
2. Functionality
The functionality of an OBD2 scanner goes beyond merely reading and clearing trouble codes. Depending on your needs, you may require a scanner that offers a wide array of diagnostic tools.
Basic models will provide you with the ability to read DTCs and clear them, which is sufficient for simple issues like resetting a check engine light.
More advanced scanners offer features such as live data streaming, which allows you to view real-time data from your vehicle’s sensors.
This is invaluable for diagnosing problems as they occur, such as monitoring engine temperature, oxygen sensor readings, or fuel trim levels.
Advanced scanners also offer special tests like ABS (Anti-lock Braking System) and SRS (Supplemental Restraint System) diagnostics, allowing you to diagnose issues with critical safety systems.
Some high-end models even provide bi-directional control, enabling you to interact directly with the vehicle’s systems to perform active tests or component activation, such as commanding the fuel pump to turn on or testing the function of individual injectors.
3. Ease of Use
No matter how powerful a scanner is, it’s only as good as its ease of use.
A user-friendly interface can make a significant difference, especially for those who are not automotive experts.
Look for a scanner with a clear, intuitive display that makes it easy to navigate through menus and read diagnostic information.
Many modern scanners come with touchscreen interfaces, which can be easier to use than older models with buttons.
Additionally, some scanners offer mobile apps or PC software that can connect via Bluetooth or Wi-Fi, allowing you to view data on a larger screen or save diagnostic reports for future reference.
Data interpretation is another aspect of ease of use. Some scanners go beyond simply displaying codes and provide definitions or suggested fixes for the codes they find.
This feature can save time and help you understand the problem without needing to look up each code manually.
4. Build Quality
The build quality of an OBD 2 scanner is a crucial consideration, particularly if you plan to use the tool frequently or in a professional environment.
A scanner with a durable design will withstand the rigors of daily use, including potential drops, exposure to harsh automotive environments, and frequent handling.
Look for scanners that are constructed with high-quality materials, such as rubberized casing for extra protection and a secure grip.
The connectors should be sturdy and well-made, ensuring a reliable connection to your vehicle’s OBD2 port.
Consider the length and flexibility of the cables, as these can affect the ease with which you can maneuver around your vehicle while performing diagnostics.
5. Price
Lower priced scanners may be appealing, but they often lack advanced features and may not be as durable or reliable as more expensive models.
If you only need to occasionally clear a check engine light or diagnose simple issues, a basic, lower-cost scanner might suffice.
However, if you plan to use the scanner frequently or need it for professional use, investing in a higher-end model with more comprehensive features could save you money in the long run by preventing misdiagnoses and providing more detailed insights into your vehicle’s health.
Higher priced models often come with additional features such as free software updates, which ensure that your scanner remains compatible with new vehicles and systems as they are released.
This can be a significant advantage, especially if you work on a variety of vehicles or plan to keep the scanner for many years.
6. Software Updates and Support
OBD2 scanners are like any other tech device; they benefit from regular updates that keep them compatible with the latest vehicles and diagnostic protocols.
ANCEL offer at least 2 years of free software updates, ensuring that your scanner stays up-to-date with the newest technology and features.
Some other scanners may include lifetime free updates, while others might charge for updates after an initial period.
In addition to updates, consider the level of customer support provided by the manufacturer.
Reliable customer service can be invaluable, especially if you encounter issues with your scanner or need help interpreting a complex diagnostic code.
Look for brands that offer robust support options, including detailed manuals, online resources, and responsive technical support teams.
These resources can greatly enhance your experience and ensure that you get the most out of your OBD2 scanner.
