The Best OBD2 Scanners

One of the most annoying aspects of owning a car is that pesky check-engine light. While we are all thankful when this light clues us in on a problem before it gets any worse, it can come on for hardly any reason at all. Getting it checked and turned off can cost more money than you might think, and repairing your car yourself is almost out of the question if you can’t figure out what the check-engine light is trying to tell you. Luckily, it is possible to purchase an OBD-II Scanner for home use. These scanners hook up to a car’s onboard computer for self-diagnostics and reporting and can allow you to figure out what is wrong with your vehicle without taking it to an expensive mechanic.

We reviewed dozens of OBD-II scanners while on our search for the best of the best. On our search, we rated each OBD-II scanner based on ease of use, customer reviews, cable length, speed, compatibility, the range of codes read, and accuracy of code definitions.

Who Should Buy an OBD-II Scanner?

Even if you aren’t very good with cars, an OBD-II scanner can save you lots of money. When you take your car to a mechanic, the first thing they do is plug in a scanner and read the codes your car’s onboard computer gives them. This gives them a pretty good idea of what is going on and allows them to fix it. However, an OBD-II scanner can allow you to view this information at home, which can save you lots of time and money. Very small, easy-to-fix problems can cause your check engine light to come on. For example, if you don’t get your gas cap on exactly right or it comes slightly loose while you’re driving, your car’s computer can occasionally detect this can turn your check engine light on. Of course, you don’t need to go to a mechanic to simply tighten your gas cap. But, if you don’t have an OBD-II scanner, that might very well be what you end up doing.

Even if the problem isn’t something you can fix by yourself, knowing the problem before you take your car over to the mechanic can help speed up the process of fixing your car. If you already know what is wrong with it, letting the mechanic know always them to get started right away. Plus, you’ll have a pretty good idea what the damage to your bank account will be before you even bring your car to the mechanic.

Important Features to Consider

An OBD-II scanner should have a few important features. Here’s what to consider when selecting an OBD-II scanner for your car:

  • Compatibility. While most high-end OBD-II scanners will be compatible with most modern cars, some of the cheaper ones only read a single protocol. This greatly shrinks the number of cars they are compatible with, which can cause you to unnecessarily spend money on a scanner that doesn’t work with your car. We suggest only choosing OBD-II scanners that are compatible with a wide range of cars. The last thing you want to do is buy a scanner you can’t use.
  • Ease of use. Car codes can be confusing, especially if you aren’t used to the complex nature of automobiles. However, many scanners were designed with the inexperienced user in mind and are very easy to use. While you might be able to get away with a more complex OBD-II scanner, we recommend purchasing one that is known for being easy to use. After all, there is no reason to make things more complicated for you than they need to be.
  • Functions. All OBD-II scanners can read the codes your car’s onboard computer provides. However, many scanners can do much more than this. Some can give you real-time updates on your car’s condition, provide you with an I/M readiness check, reset the emissions monitor, and completely delete codes altogether. You might not necessarily need these features if you’re only planning on using your scanner to turn off your check engine light. However, if you enjoy working on your car, you might benefit from purchasing a scanner with these extra features.
  • Display. An OBD-II scanner isn’t much use if you can’t read it. Scanners tend to vary a lot when it comes to their displays. Therefore, make sure that whatever scanner you purchase has an easy to read display. Color isn’t necessary but can make things easier to read.

Frequently Asked Questions

What is an OBD2 Scanner and how does it work?

An OBD-II scanner stands for Onboard Diagnostic II. It is a standardized system onboard car computers use for self-diagnostics and reporting. In other words, it is a standard “language” cars use to tell mechanics and owners what is wrong with them. Whenever a monitor notices something is wrong, the car’s computer automatically generates a code. An OBD2 scanner can read this code by being plugged into your car, which helps you or a mechanic figure out what is wrong with the vehicle. An OBD2 scanner is different from previous models because it is not specific to each brand of car. In 1996, California regulated and designed a new code for cars that went across all brands. Previously, each brand had used their own specific code, which meant that each brand of car also had its own scanner. Now, however, the code is the same across all brands. This makes it easier to run diagnostics on vehicles because you only need one scanner instead of dozens. An OBD2 scanner is simply a scanner that reads this standardized code instead of an outdated, brand-specific one.

What’s the difference between a basic code reader and a scan tool?

Both of these devices have a similar purpose – they communicate with your car’s computer. However, while both devices can read and clear basic code, a scan tool often has other features as well. Usually, a scan tool can also read more advanced data, playback previous codes, be used to interpret each code, and run diagnostic procedures.

Basic code readers are usually cheaper and easier to use but have very basic functionality. In many cases, it is simply more productive to go ahead and purchase a scan tool that has more advanced options. Even if you aren’t planning on using these advanced features now, you never know when you’re going to need them. Plus, scan tools aren’t usually that much more expensive than a basic code reader. When you compare how many extra features you’re getting, you realize that they really are a great deal.

What does OBD2 stand for?

OBD2 stands for Onboard Diagnostic II. The two simply represents that it reads the newer, post-1996 codes instead of the earlier, brand-specific ones.

What type of OBD is my car?

If your car is U.S. made and has a model year of 1996 or later, an OBD2 scanner is the correct one to get. The same is true if your car is an import from 2001 or later. If your car is not in one of these ranges, you will need to purchase a brand-specific reader in order to check your vehicle. We recommend checking in your car’s owner manual to figure out the correct scanner to purchase.
