What Is The Best OBD2 Scanner?

If you own a car, having the best OBD2 scanner is essential for diagnosing any problems with your vehicle's engine or other systems. This can save you a costly trip to the mechanic. An OBD2 scanner is a tool that can read and interpret the diagnostic trouble codes (DTCs) generated by your car's onboard computer.This helps you identify any issues with your car's systems, such as the engine, transmission, or emissions.  

 But with so many options on the market, it can be difficult to know which scanner is the best for your needs. In this blog, we'll go over the most important factors to consider when choosing the best OBD2 scanner and recommend some of the best options available.


Factors to Consider

Here are some of the key factors you should consider when selecting an OBD2 scanner:

  • Compatibility: Make sure that the scanner you choose is compatible with your car's make, model, and year. Some scanners only work with certain types of cars, so be sure to check that your vehicle is covered before you make a purchase. If you are unsure you can contact us we can let you know.

  • The diagnostic capabilities of the scanner are also important. Most basic OBD2 scanners around $100 and under only provide basic diagnostic information, such as trouble codes from the engine management system, while others can provide detailed information about specific systems in your vehicle, such as the engine, transmission, or ABS. Look for a scanner that can provide the level of diagnostic information you need. 

  • Price: Scan tools can range in price from under $50 to over $8000. Consider your budget when making your selection, and choose a scanner that offers good value for the money. If you only need a basic scanner that reads and clears engine codes then all of the basic scan tools are going to offer you the same functionality. So its just a case of looking at the different scan tools and choosing what one you like the look and price of.

  • User-friendliness: Some scanners are more user-friendly than others. Some more advanced scanners have a touch screen, and some can work through an app on your mobile phone. Consider how easy the scanner is to use and understand, especially if you're not a professional mechanic. At Premium Diagnostic Equipment we offer our own in-house remote support. If you are having trouble with your scan tool or need help diagnosing a vehicle you can call up and speak with a qualified technician who can remotely log into your scan tool and assist (providing the scan tool has this option)

  • Wireless Connectivity: Finally, consider whether you want a scanner with wireless connectivity. Some scanners can connect to your smartphone or tablet via Bluetooth or Wi-Fi, allowing you to view diagnostic information on your mobile device. Some have a hard wired cable connection and some communicate via a bluetooth dongle back to the scan tool. When comparing the same model of scan tool with a cable connection and a blueotooth connection, the bluetooth option is usually a bit more expensive.
