What Is an OBD2 Scanner?
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?
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.
Best OBDII Scan Tool Review
Undeniably, without an OBD2 scanner, you may have to take your car into the shop to figure out what is wrong with it. However, this can take a large amount of time and money that you may not have. On the other hand, though, a good OBD2 scanner can help you distinguish between a broken catalytic converter or a blown gasket, all in-home and without getting your hands dirty.
The list of the 20 best OBD2 scanners below will help guide you in finding the right tools to diagnose any problems with your car.

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.
Types of OBD Scanners
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 means that it’s slightly different in 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.
A Code Reader, a DIY Scanner, or a Professional Diagnostic Tool?
For the average car user, a Code Reader or DIY Scanner is going to be sufficient for your needs. Which OBD2 scanner you decide will depend on how much detail and information you want to get from your car.

If you want some more detailed information and monitoring, a DIY Scanner is the best option. It allows you to get a deeper look into your car’s performance and can even help maintain your car’s health over the long term.
