Best OBD Scanner: Complete Review And Buying Guide 2019

An OBD scanner is a tool that allows you to read the trouble codes on your car’s On-Board Diagnostic (OBD) system.

Looking for the best OBD scanner? You’re in the right place. In this article, we break down everything you need to know about what to look for in an OBD2 scanner.

An OBD scanner is a tool that allows you to read the trouble codes on your car’s On-Board Diagnostic (OBD) system. It’s a tool that you plug into your car’s OBD interface to read the information from your car’s OBD system.

There are different types of cars for different OBD systems. Depending on your car, it will either have an OBD1 or OBD2 system. OBD1 was originally created to monitor basic car emissions and systems in the early 1990s.

Starting in 1991 OBD1 was the California standard but several models started implementing OBD1 in the 80s. OBD2 is an upgraded, standardized OBD system that was required to be used by all car manufacturers starting in the 1996 model year.  

OBD scanners work by communicating with the computer system in your car to read any trouble or error codes that the diagnostic system displays. These trouble codes are triggered when the computer in your car detects that something is not functioning properly. To use an OBD scanner, you simply plug it into your OBD interface on your car, turn your key to power the scanner, and scan for any error codes in your diagnostic system.

To use an OBD scanner, you simply plug it into your OBD interface on your car, turn your key to power the scanner, and scan for any error codes in your diagnostic system.

OBD1 Vs. OBD2 Scanner

As mentioned before, OBD1 and OBD2 are different types of diagnostic systems that essentially monitor the same functions in your car. OBD1 was used on car models between the late 1980s and 1995

This system was not standardized, so it varied between car manufactures, which mean that it’s slightly different on each car. After 1995 however, OBD2 was implemented and required to be the same on all cars.

If your car was manufactured between 1980 and 1995, you’ll need an OBD1 scanner. If it was made in the 1996 model year or later, it will use an OBD2 scanner. Most people will need an OBD2 scanner so that’s what we’ll be covering in this article.

3 types of OBD2 scanner

There are 3 different types of OBD2 scanners: code readers, DIY scanners, and diagnostic tools. There are a few differences between them that you should be aware of before you decide which is best for you

Code readers are the most basic type of OBD2 scanner. They are low-cost and they simply read the Diagnostic Trouble Codes (DTCs) that are on your OBD2.

These codes are made up of a letter followed by four digits. To find out what the code means, you can look it up online.

DIY scanners are more advanced and offer you a more in-depth look at your car’s diagnostics. Some DIY scanners are traditional, corded scanners that you plug into your OBD2 interface.

Other DIY versions involve an adapter that you plug into the interface and then send information directly to an app on your phone. DIY scanners can read basic DTC codes as well as provide more detailed information like fuel usage, average speed, etc.

Diagnostic tools are more advanced OBD2 scanners, typically used by professional mechanics and serious car enthusiasts. They can read, graph and save a large variety of data from your vehicle.

They can monitor pretty much anything you would ever want in your vehicles diagnostic system and are pretty much universal to any vehicle. Although they are much more sophisticated, they also come with a much higher cost. Depending on your needs, this might be the best OBD2 scanner for you.

Should I take a Code Reader, a DIY Scanner, or a Professional Diagnostic Tool?

What Is an OBD2 Scanner?

an OBD2 scanner is a specialized device that is made specifically for plugging into and extracting data from OBD2 systems.

Basically, all commercially available cars nowadays come equipped with onboard computers that monitor and collect data on the performance of a car’s various systems over time. For instance, Onboard Diagnostics 2 (OBD2) is a standardized system that computers in cars use for self-diagnostics and reporting.

So, the point of ODB2 technology is to give an industry-standard method for monitoring and checking car performance. Particularly, OBD-II systems work by monitoring sensor inputs and outputs and sending a “trouble code” if anything is out of place. Also, the OBD2 system in your car is the thing that turns on your “check engine” light when it detects something wrong or when it is time for routine maintenance. Therefore, it’s clearly an important system to keep an eye on.

To explain, OBD2 systems monitor a large amount of data at each point in time, and an OBD2 scanner is a specialized device that is made specifically for plugging into and extracting data from OBD2 systems. Most important, an ODB2 scan tool can read and analyze diagnostic messages from the OBD2 system and helps with diagnosing car problems, among other things.

To begin with, standard OBD2 systems are equipped with a universal connection interface, which is normally found just under the steering wheel of your car. Above all, with the appropriate cables, your ODB2 code reader can plug directly into your car’s diagnostic systems. Then, it reads/analyzes diagnostic messages to aid in the repair and return to service.

Why Is a Good OBD-II Scan Tool Important?

A good OBD2 code reader can be a lifesaver for emergency situations where taking your car into the shop is just not an option.

Firstly, having a good OBD-II scan tool can save you a lot of money on car repairs. Evidently, the main reason for this is that having your own way to check up on your car allows one to diagnose and potentially fix problems without having to take your vehicle into the shop. Secondly, a good tool for regular checking will help you stay ahead of future problems, which can extend the life of your vehicle.

Moreover, without an OBD-II code reader, it takes a lot of technical knowledge and skill to check your car’s different systems. After all, the best OBD-II diagnostic tools take the technical knowledge out of diagnosing your car’s problems and relays that information in a simple to understand visual/graphical interface.

As a result, a good OBD2 code reader can be a lifesaver for emergency situations where taking your car into the shop is just not an option. For instance, say you are driving through a sparsely populated region and your check engine light comes on. Even if this happens, you can use your OBD2 code reader on the spot to diagnose and fix any problems right on the roadside.

Kinds of OBD-II Diagnostic Tools

In particular, there are two major types of OBD2 diagnostic tools you are likely to come across: code-readers and scan tools.

The first type, code-readers, are simple no-frills devices that plug directly into OBD2 interfaces and can read and clear codes. OBD-II code-readers are typically less expensive, but they do come with some limitations. For example, a lack of knowledge about the manufacturer-specific code. So, they sometimes cannot directly pinpoint the cause of a diagnostic error message.

The other type, scan tools, are more advanced varieties of code readers that come with more functionality. Because of this, scan tools normally have more manufacturer-specific information. Because of this, scan tools can do a lot more. Along with reading and clearing codes, an OBD-II scan tool can:

  • Store and playback data
  • Graph information about systems
  • Provide manufacturer specific diagnostic procedures
  • Provide trouble code definitions

Because they come with more functionality, OBD2 scan tools are typically more expensive than code-readers. But, they make up for the bigger price by giving more tools for self-diagnosis and repair.

To sum up, whether you should opt for an OBD2 code-reader or an OBD2 scan tool depends on your technical knowledge and how much you want to fix your car yourself. For those who may not have a lot of technical knowledge and experience with cars, an OBD-II scan tool gives one much more information to work with and more things to do. Alternatively, a simple code-reader may work for more experience car enthusiasts, or who already have some knowledge about manufacturer specific ODB2 systems.

What Are the Best OBD2 Scanner?

The answer to the ideal OBD2 scan tool will ultimately depend on your interests. However, here are a few recommendations to set a baseline, to begin with.

To sum up, with respect to simple Bluetooth compatible code-readers, you can’t beat the BAFX OBD Reader. Without doubt, the smartphone compatibility really takes the bulk of the technical know-how out of diagnosing car troubles and is very affordable. The two-year manufacturer warrant is also a nice addition to make buying stress-free. However, the sole drawback is the required third-party app purchase to interface with the device.

With this in mind, a decent mid-grade device for diagnostic needs is the BlueDriver Pro OBD-III scan tool. Like the BAFX, the BlueDriver is smartphone compatible and easy to set up and use for the technically inexperienced. That is to say, the BlueDriver offers a wider range of functions than the BAFX, and also does not require a third-party app purchase. In short, it is more expensive, but the extra cost is worth the features.

Lastly, if you are looking for an affordable comprehensive OBD2 diagnostic tool, then you cannot go wrong with the Autel MaxiLink. In short, it offers a great mixture of simplicity and functionality, all at a great price-to-quality ratio. Hence, the advanced diagnostic tools can be used for some non-OBD2 features and have extensive vehicle coverage. Similarly, the powerful graphing tool and constant software support make sure that you will always be prepared to do some diagnostic work.

The Bottom Line

Overall, picking the right OBD2 scanner involves choosing the right mix of simplicity, functionality, quality, and price. Surely, novices and those new to car maintenance would most likely benefit best from a simpler code reader that handles basic functions without getting too deep in the nitty-gritty technical details. On the other hand, those more experienced and knowledgeable about cars may opt for a more sophisticated diagnostic tool, so it can give precise details on system performance. Notwithstanding, this review of the 20 best OBD2 scanners of 2019 will help guide your purchase.
