The Best OBD2 Scanner

We want our cars to be reliable. For most of us, that’s all about getting from Point A to Point B without any hassle. As long as you maintain quality care for your car, that’s not too difficult to do. Check the oil every now and then, take it to get a routine checkup once every three months, keep the tires inflated, and keeping it clean are things you can do without having to talk to a mechanic.

Sometimes, however, the unexpected happens and that routine gets thrown off. The check engine light comes on and after the typical one day of driving around with it on (just to make sure it’s legitimate), you might need to think about taking it in the shop.

That’s why many people carry around an OBD2 scanner with them, to be able to see what’s wrong with their car. Even though they may not be able to fix it, you can receive a reliable report on the issue.

Don’t worry, you don’t have to be tech or auto-savvy to use one. There are plenty to pick up at low costs, which will save you money from having to overpay a mechanic and make sure you keep going from Point A to Point B.

OBD2 Scanner Buying Guide

Not every scanner is made equally and not every scanner is going to work for you. Before you head out and purchase the first scanner you see, run through the checklist below to make sure you’re answering all the right questions and figuring out what you need to be doing.


Device Type

With smartphones weeding their way into just about everything these days, the OBD2 game is changing. When looking through devices, you’ll find plenty that require a third-party app to use. Most of these apps are free, but some require purchases.

In addition, many of those wireless devices connect via WiFi, Bluetooth, or both. Make sure that the device is compatible with the phone or tablet you’re using as well. Many are compatible with all devices, but you just want to double check before making a purchase.

If you’re going the traditional route, you’ll be plugging the device into your vehicle itself. These handheld units don’t require an app or third-party system, but will need to be connected to the internet if you’re going to update them on a regular basis.

Even though these older scanners are wired connections, that doesn’t mean they’re from eons age. Many have LED or color screens and are plenty easy to figure out when you first start using them.

There are also some scanners that are hybrids, which use remote plugs and run on their own software. These are less common, but you may run into them while shopping around.


Power Source

All scanners that have a cable option run off of the vehicle’s battery. Don’t worry about draining the battery, as they don’t take much to get up and running. Newer, handheld units offer a variety of options.

Some can attach to your car battery while others come with their own rechargeable or replacement batteries. Those devices that need charging often need a lot of charging, so be prepared to let them sit overnight if you use your scanner frequently.


Data Transfer

With the newer devices, you’ll be transferring your data via Bluetooth functionality  or WiFi. Many people prefer Bluetooth, as you can use it anywhere and it takes just moments to connect. WiFi can sometimes be unstable and the network may not reach to where you are.

The older models don’t have any data transfer per se, as all of the information is going to show up on your handheld device. There are some that are compatible with printers or computers for transferring information over, but many of them will just show you the code or error message on the screen.

That being said, all of your devices will rely on firmware and software updates. For many, it’s simple to have an app on their phone that updates automatically instead of plugging the device into the computer to download any updates needed.


Vehicle Compatibility

By far the most important factor to consider when checking out devices, most all devices will claim they are compatible with just about any type of vehicle. Sure, some will mention brands or countries where cars were made, but many try to be as universal as possible.

Check out any online or Amazon review of these scanners are you’re bound to find someone saying that X device is not compatible with their car. There is also fine print that needs to be read ahead of time, just to make sure.

It’s best to do a little of everything, scouring online reviews and forums while also making sure to read the company’s website. You can return the device easily, but that’s a hassle and you’d rather have something working from the very beginning.


Device Compatibility

This really only pertains to those who are purchasing the newer models. If you have a scanner that connects to the vehicle with a cable, you won’t have to worry about this as much.

But if you’re going to be relying on a scanner and an app, it’s important to make sure that your scanner is going to work with your device. With two big names on the market, Apple and Android, it should be pretty easy to see if the scanner will work with your device.

Most work with both devices, but there is the off-chance that one could be platform exclusive. Also, not all the apps you may find will work with your device. Be sure and do a test run ahead of purchasing your scanner.


Update Requirements and Manufacturer Longevity

You may often hear someone say, “they just don’t make ‘em like they used to.†This usually pertains to big purchases, like furniture or cell phones that seem to stop working whenever the latest model comes out.

Fortunately, many of these scanners are meant to last years. As long as you keep them updated, most of them should keep working for the foreseeable future.

If you want to upgrade to a newer unit, with a better screen or one that works faster, then that’s up to you. Technology will continue to have a significant impact on scanners, meaning the latest version may be leaps and bounds better than what’s currently on the market.

That being said, some manufacturers require subscriptions for you to continue using their services and staying updated. Make sure you’re reading the fine print here as well. Some will give you the first year free but then charge a subscription after that, while others will give you updates for as long as you have the device.

Be wary of some apps too. While some on the market may be in the $30-40 range, there are plenty of free apps that will work with your device.


OBD2 Scanner FAQs

If you’ve gotten to this point and you’re not even sure what the scanner is or what it does, then below there are some important questions and answers for you.

It will help you better understand what exactly these units do and why purchasing one may be the right decision for you.


How exactly does an OBD2 scanner work?

These scanners work by interacting with your vehicle’s onboard computer. Formerly known as the OBD-II connection, it is primarily used for emissions testing. When you go get your emissions test every year, the inspectors plug a device into your car in order to make sure you’re not emitting over your limit.

While that’s the primary purpose, it’s also an area to access the information that you vehicle is storing on the computer. So whenever an error message comes up, such as your change oil light, check engine light, ABS light, etc., your onboard computer has detected and recorded that error.

You can plug your scanner into your car and find out what exactly is causing that error. As mentioned above with the variety of devices, sometimes it will tell you it’s a certain code and explain the problem or it will just tell you the code, leaving you to go Google the answer yourself.

Usually, you’ll need to perform some kind of maintenance to clear the code and fix your vehicle.


Does the scanner clear codes?

Well, it depends on the scanner. Some do and others don’t. Some require you to fix the issue before you can fully clear the codes out. Others will let you clear the code after you’ve assured the scanner that you’ve done your due diligence and looked at everything.

Sometimes, you will have to make the necessary repairs and then wait to re-scan your vehicle. Only then will the code be cleared and everything will return back to normal.


Do scanners work with all vehicles?

If you’re doing some cursory shopping, you’ll no doubt see wonderful guarantees assuring you that their scanner works with every vehicle. It’s a one-size-fits-all approach!

For those that don’t, they usually give a specific time frame to when they would work with certain cars.

Some will advertise that they only work with American made cars while others will boast that they work with imported cars as well.

But be aware, even those that claim to work with all vehicles may face compatibility issues. You’d be hard-pressed to find a scanner that did not have some kind of compatibility issue in an online review.

The issue with vehicles usually lies in how the brands have programmed their onboard computers. Some may have specific codes that you’ll have to visit a dealership in order to receive an explanation.


After all that, where do I even plug the scanner in?

You just throw it in your car and hope it does the rest!

Every car is different. Even vehicle’s makes will vary by year and models could vary entirely. It’s best to thumb through your vehicle’s manual in order to find the right answer so you’re not on your hands and knees looking for a place.

There is no uniform location, but some of the most common ones are: under the driver’s seat, under the steering wheel, inside the glovebox, or even somewhere in the center console. So if you don’t want to leaf through your manual, it’s best to start there. If that’s too much, head to YouTube where someone has uploaded a video.

Rest assured, the port will have some kind of label on it or even a small cover. Gently remove the cover (don’t lose it) and plug your device in.


Which scanner is the best scanner for me?

Unfortunately, there’s no right answer here. The answer to that question largely depends on you. It largely depends on what you do, what you want, what kind of car you have, why you want to diagnose your vehicle, and what kind of tech device you own.

If you’re looking for something that will give you constant, live information then you want something that has got its own battery power or uses little of it. You can hook it up to a smartphone in order to keep you from constantly having to check the information.

If you’ve got a home garage or your own home mechanic, then you’re going to want to invest in one that’s standalone and doesn’t require a smartphone or tablet to operate. You want it to be dirty and have its own system that you can look at immediately.

The reasons for this are obvious. If you’re going to be using it on a regular basis, the last thing you want to do is be pulling out your smartphone looking for answers. That’s just asking for your smartphone to be knocked out of your hands and lost to the abyss forever.

If you’re someone who has just a basic interest in cars, then look for one that can be plugged in and connected to your phone. It doesn’t have to be one that’s plugged in, but having a scanner you can pull out, plug in, and find the error code could save you lots of time and money in the future. Plus, it will help you have a better understanding of how your vehicle works.

You’re bound to find plenty of OBD2 scanners out there, but just make sure you’re doing enough research to find the one that’s ideal for you. At the end of the day, you’re taking a great step in protecting the well-being of your vehicle and making sure you keep going from Point A to Point B.
