Buying Guide and FAQs

Guide to Finding and Buying the Best OBD2 Scanner

As you can see, the market offers a multitude of brilliant and worth-considering choices when it comes to OBD2 scanners. However, you can’t just settle for the very first product that catches your attention. What you need is the best – the one that can offer the best value for your money. 

The latest OBD2 scanners have become future-proof, which means they can endure the test of time and last for a long time. A lot of them receive updates to discourage you from buying a newer model. The following are the most important features that you should check out when searching for the best OBD2 scanner. 

Ease of Use

One of the major concerns of novices is the ease of use. No questions. Most of the OBD2 scanners are easy to operate. All you have to do is follow the provided instructions in the manual. From the simple, easy-to-press buttons to those programmable controls, users must find these tools easy to use and helpful when dealing with car codes. 

The older your vehicle, the more complicated the diagnostic tests can be. You will need more tests to run in dealing with different problems that may come along the way. It ranges from the check engine warriors to ABS mistakes. 

Connectivity Choices

The connectivity choices can be wireless or wired when the OBD2 scanner is designed to send data to the PC or mobile phone. A few of the latest scanners feature Bluetooth connection that allows the drivers to set their preferred standards in terms of data transfer. 

It’s best seen if the data has been interpreted with an application that drivers preferred to use. Most of the OBD2 scanners are well-suited with many mobile apps. 

Kinds of Codes

The OBD2 scanners are capable of reading various kinds of codes. A few can be general codes like the Check Engine codes or anything specific to other vehicles. More specific codes may apply from one car model to another. So, you have to search for the best OBD2 scanner that will match your car, and you need to consider the kinds of codes that apply to your vehicle. A universal OBD2 scanner must be enough if the drivers don’t have specific requirements. 

Smartphone and Car Compatibility

Some of the OBD2 scanners are already compatible with mobile phones. Both iOS and Android devices come with corresponding scanners. Likewise, most of the scanners are crafted to work on different cars. If they now recognize a particular kind of car, one simple update will suffice to fix the issue. However, the hottest OBD2 scanners can recognize and diagnose most European, American, and Asian car models.

Looking at the list of the features that the modern scan tools come with will be enough to provide a much better respective on the compatibility probabilities. An accurate and efficient scanner may be required when the Bluetooth connection is a must because the wireless data transfer is not yet available as a standard feature on various scanners. 

Another crucial element to consider will be your personal preference. In certain cases, the drivers choose the models equipped with the built-in screen that eliminates their need for a smartphone that can also make the entire process more complicated. In such cases, it’s best to find a good unit with a nice display.

Options for Customization

The customization choices are extremely limited on the OBD2 scanners. Many of them are user-friendly and not primarily intended for professionals. Those users who can get technical and with a hands-on approach to devices are frequently the ones who will give their best in terms of customization. However, additional customization is often incorporated in the premium products that are more ideal for mechanics. 


What is the difference between the OBD1 and OBD2?

Drivers were using the OBD1 scanners until 1995. A year after, the OBD2 system has been introduced. The OBD1 and OBD2 may have similar underlying principles. However, they tend to differ from each other when it comes to functionality.

Where can I find the OBD dock inside my vehicle?

Most vehicles have their OBD ports underneath the dashboard, just underneath your steering wheel. However, in some cars, the OBD port can be seen below the gearbox, on top of the pedals, or inside the passenger compartment. The case will always be different from one car to another. 

What is the Check Engine Light?

It is the warning light that will signify the malfunction within the ECU (engine control unit) or ECM (engine control module).

What Is the ABS?

The acronym ABS stands for the anti-locking braking system. This is the one that prevents the wheels of a vehicle from locking up if you touch the brake. The ABS plays a crucial role when it comes to your car’s efficient control and security.

What is SRS?

The extra restraint system is the one responsible for controlling the airbag. 

What is an EVAP system?

The evaporative emission control system or EVAP prevents the gas from leaks and escape to the air. It guarantees minimal pollution.

Does one OBD2 scanner work for more cars?

Yes, you can use just one OBD2 scanner, but only if all your vehicles are compatible with the scanner.


The best OBD2 scanner is so important and a quite expensive tool. So, you have to invest in one that can satisfy you at every angle. Hopefully, this buying guide helps you come up with a good decision.
