Top 5 Best OBD2 Scanner [2024 Guide]


OBD2 Scanners are the closest thing we have to a professional mechanic when driving too far away to access quality car-diagnostic services. Keeping one in your car is a great tool for saving money every time the check engine light pops up.

On-Board Diagnostic Scanners (OBD scanners) work by plugging into the car’s access port and scanning for possible problem through your car’s computer system. After reading through and checking for any possibility of a problem, it indicates the code. Thereafter, it shows you what needs to be done to fix the issue. From that, you can automatically determine whether you can handle it or need the help of a professional.

More-recent OBD-II scanners will also go through your car’s critical systems and read your engine and transmission for error codes. That is the basic information a mechanic reads from your car.

Here are the top 5 Best OBD2 Scanners in 2024 and a buying guide.

 How to Choose the Best OBD2 Scanner?

Choosing an ideal OBD2 scanner can be hard, especially now that the market is full of them. Therefore, in the same way we take our time choosing our favorite items, we should also consider what OBD2 scanner to buy.

OBD-II scanners come in different forms and features. Therefore, which features should guide you in selecting the best OBD2 scanner?

1. Purpose

You need to know what exactly your OBD2 scanner will be used for. For example, you just want an OBD2 scanner which can read and erase some basic codes or a scan tool with ECU programming which allows you to reprogram your vehicle.

2. Compatibility

If you need an OBD2 scanner, you need to ensure that it is compatible with the OBD2 port of your car. Let’s say, for instance, your car was manufactured in 1996 and up to date, you’d be sure the OBD-II scanner is compatible with it. For those cars made before 1996, you’ll need an OBD-I scanner.

In other instances, some OBD2 scanners only work with locally-assembled vehicles, while others only work with Asian/European cars.

Some OBD2 scanners work on light cars, while others do well in trucks. If you own both, you need to ensure your scanner supports both vehicles, so you don’t purchase two OBD2 scanners.

3. Connectivity

Connectivity to a mobile app helps save the inconvenience by displaying the error codes and the possible solutions. Some apps display a tutorial on how to handle the problem too.

Mobile apps can only connect to your car via either Wi-Fi or Bluetooth. The latter works well in Android devices, but Wi-Fi tends to do better with iOS.

4. Information Processing

Information Processing starts right from how the scanner gets database updates. That is important in ensuring your scanner can detect new error codes and know how to deal with them appropriately. That saves on time and money you could have used on a professional mechanic.
