OBD2 Scanner Buyer’s Guide

With an OBD2 scanner, running diagnostics on your vehicle is a breeze, in fact you can usually get a reading in under a minute. A car has a computer system that monitors a variety of subsystems that make a vehicle run. The onboard diagnostics scanner allows users to check the status of their vehicle without having to take it to a mechanic and pay a fee for the same service.

Models that run on Bluetooth allow you to use your smartphone or tablet as a diagnostic scanning tool. Using apps that communicate with the scanner when its plugged into your vehicle makes the process even simpler.

While there are many different types of scanners on the market to choose from, wireless Bluetooth models are more convenient and easier to use compared to traditional models.

But before I go over what features these innovative easy to use scanners have to offer, first, let’s discuss the benefits of owning your own OBD2 scanner.

Bluetooth OBD2 Scanner Benefits

bluetooth scanner control

  • When a sensor in your vehicle detects an issue, the car’s computer produces a code and the check engine light will turn on. This light indicates that there’s an issue somewhere in the system. However, without reading the code from the onboard computer, the vehicle owner will have no idea what the issue is. In order to read the codes, the vehicle owner will need to take it to a local garage and have a mechanic run diagnostic tests or the owner can simply purchase an OBD2 scanner. Running diagnostics will cost money, so if  you take your vehicle to a mechanic every time your check engine light turns on, you’ll have to pay a fee. But if you have a scanner, you can do the same tests yourself, for free.
  • These portable devices can easily hook up to your vehicle and will display any trouble codes that pop up. This knowledge will be invaluable when it comes to either the car owner fixing the problem themselves or figuring out how much money it’s going to cost them to have a professional do it.
  • When you own a code scanner, you can easily do your own diagnostics. All you need to do is locate the OBD connector which is usually placed on the driver’s side, under the dash. Once you’ve located the connector, you’ll follow the connection instructions for the scanner. When you run the diagnostics, the codes will instantly pop up on the scanners display or your smartphone or tablet.
  • Sometimes a check engine light will turn on for a serious problem, one that will make it unsafe to drive your vehicle until it’s been repaired. In some cases, the light will turn on when a sensor is out. While it’s important to get that fixed, it’s not something that will require immediate action. The ability to read trouble codes yourself will help determine the severity of the problem.
  • These scanners are very versatile and will work for many different makes and models of vehicles. In 1996, manufacturers were required to use a standard diagnostic method. This onboard diagnostic system allows users to purchase a single scanner for a variety of vehicles. This means car owners will not have to buy a new scanner every time they get a new vehicle.
  • These devices are highly portable, so you can bring one along when you head out on a long car trip. This way, if your check engine light pops on when you’re on the road you can whip out the scanner and determine whether or not your car is in need of immediate repairs.
  • The ability to pinpoint the source of your vehicle’s check engine light means that you’ll be more likely to handle the problem yourself. Some scanners will provide more information than others.
  • If you don’t know much about your vehicle and you’ve never done your own repairs, having a scanner can come in handy to ensure your mechanic isn’t charging you for repairs you don’t need. Most mechanics are honest, but there are some who will overcharge a client who obviously has no idea what’s going on with their vehicle and doesn’t have much knowledge in terms of automotive repairs. Knowing exactly what’s wrong with your vehicle before you bring it to a mechanic will allow you to do a little research online to find out how much the repairs will cost.

Other Important Features

When a check engine light pops on, this indicates that the car’s computer has detected some type of error. This can be anything from a dead oxygen sensor to a loose fuel cap. The error pops up as a code, which will remain stored in the computer’s memory until it has been cleared either with a predetermined reset, a number of engine starts without further issue, or by using a special tool.

OBD2 devices will come in handy for a variety of reasons, especially if you’re someone who is capable of working on your vehicle yourself. But there are many features you’ll want to look for before you purchase a scanner. For starters, if you’ve never used one before, you’ll want to purchase a model that has a reputation for ease of use. Additionally, a scanner should be compatible with both your smartphone and your vehicle and should provide codes within a matter of seconds. Unfortunately, not all models are created equal.

Now, let’s take a look at the basic features these devices have to offer and discuss why a scanner will be invaluable to both the DIY mechanic and the drivers who don’t have much mechanic knowledge.


The codes that a car’s computer generates can be checked with a scanning tool. These tools are a standard piece of equipment at any garage. These scanners can be very simple to use, but you can also come across models that are more feature-packed and thus more challenging to use correctly. The devices themselves consist of a small piece of hardware and an LCD screen, a primitive operating system, and a few buttons. The scanners are preloaded with trouble codes from a wide range of manufacturers and they’re designed to assess an engine’s performance, quickly and efficiently.

Bluetooth Capability

You’ll also come across a number of pro-quality models that are designed for smartphone use. These compact devices will connect to the serial portal in your vehicle, transmitting data over Bluetooth and interacting with an app on your tablet or smartphone. These scanners will allow you to read and clear codes and have a better reputation for more accurate readings.

These devices work by translating the data that’s output from a vehicle’s computer using the OBD interface.

Since everyone has a smartphone these days, using one of these Bluetooth devices is incredibly convenient.


Some scanners will have brand specific apps, while others will allow users to choose from a wide variety of apps based on operating systems. Most of these apps are free, however, there are some that will require a small fee to install it.


Some higher priced scanners can require a monthly subscription fee to use the dedicated app. Often, these scanners will offer a free six to twelve-month subscription, then they’ll begin monthly charges after the trial period is over. The subscription fee can be as low as $2 a month, up to $20 a month.

OBD Compatibility

One of the biggest concerns buyers will have to deal with is choosing a model that’s compatible with their vehicle. Before you purchase a scanner, you need to ensure that the model you choose is compatible with your vehicle. This can be done by reading the product’s spec sheet. Not all scanners will be compatible with every car. If you have a newer vehicle, then you’re probably in the clear. However, if you have an older vehicle, then you may run into some issues when it comes to finding a model that will work with your vehicle. As of 1996, all vehicles that were sold in America have been required to be OBD compatible. Basically, if your vehicle was manufactured before 1996 then you probably won’t be able to use an OBD2 scanner. Additionally, when it comes to compatibility, you’ll also need to check if the scanner is compatible with the type of smartphone or tablet you use. If you have a major brand of phone or tablet, then you shouldn’t run into any compatibility issues.

Trouble Codes

Every model will list the trouble codes after a scan has been completed. Once you have the trouble codes, you can do a quick online search if your scanner doesn’t have a code library. This can help you diagnose what’s going on with your vehicle. If you have a higher priced scanner, the tool may provide you with the description of the trouble code, which will make the process much faster. Some models will even provide information that’s vehicle specific. Once you have determined what the codes mean for your vehicle, you can use this information to make the necessary repairs and to purchase the right parts. If the repairs are beyond your skill level, then you can take this data to your local mechanic.

Code Library

Top of the line models that come equipped with an onboard code library can save you plenty of time and effort that would otherwise be spent looking up the code definitions. These code libraries will allow you to quickly perform a search for the code definitions, so you can learn more about why the check engine light keeps turning on and pinpoint exactly what’s going on with your vehicle. Unfortunately, not all models offer this feature, which is a must-have for people who don’t have much car repair experience.


Basic models that will provide just the codes, can run anywhere from twenty dollars up to forty dollars. Models that will display the codes and a description of what each of the trouble codes mean will cost more, but this ability can save you plenty of time and money. On average, these scanners can cost $30 to $100. The more information a model provides, the higher the price tag.


The warranties available can range from ninety days to two years. Higher priced models will often come with better warranties that offer more coverage, while low-priced scanners may not come with a warranty at all.

Ease of Use

Some models will be easier to use than others. If you don’t have much experience working on cars or you’ve never used an OBD2 scanner, then you’ll want a model that has a reputation for a beginner-friendly interface and one that includes intuitive controls.

Connecting and Reading an OBD2 Scanner

  • Using an OBD2 scanner is pretty straightforward. Before you start, you’ll need to familiarize yourself with the scanner’s user manual.  After you’ve learned about the basics of the scanner, you’ll need to download an OBD2 scanner app on your tablet or smartphone, then pair it with your device.
  • You will also want to update the scanner’s software before you use it. Many scanner manufacturers will offer software updates, which will update the model’s code database. This is often done by plugging the scanner into a computer via a USB cord.
  • Next, you’ll plug the standard connector into the vehicle’s port, which is located on the driver’s side of the dash. Turn your vehicle on in order to power the scanner. You may need to enter vehicle specific information such as the VIN. In order to check for the engine codes, you’ll press the scan button and follow the instructions that pop up on your tablet or smartphone.
  • A scan will usually take about thirty seconds. Once the scan is completed, follow the screen prompts to see if your vehicle is reporting any error or trouble codes. Make sure you record the data. If you want to see if the code was a one-time issue or you’ve used the data to repair the vehicle, use the scanner to clear the reported codes. This resets the check engine light.

Frequently Asked Questions

Are all OBD Readers the Same?

All vehicles will use the same definitions when it comes to generic codes. For enhanced codes there are models available that are vehicle specific, however, the accuracy can vary from one year to the next, so the codes may be out of date by the next model year.

What is the Difference Between an OBD Reader and Scanner?

A code reader is essentially a simplified version of a scanner. This type of tool is only able to perform basic scans for trouble codes. A scanner can read and clear codes and may also be able to read advanced data and can come with knowledge bases and playback features, in addition to diagnostic procedures.

How do I Permanently Delete Engine Codes?

In order to clear trouble codes using a monitor cycle, you’ll begin by repairing the issue that caused the trouble code to appear. Once the repairs have been made then you can clear all the codes.

How Can I tell if my Engine Code has Been Cleared?

On the scanner, you’ll press enter or read, depending on the model of scanner you have. Next, you’ll scroll down to the I/M readiness menu and choose it. Take a look at all of the systems. If the majority of them say not ready, then it means that the check engine light has recently been reset.

How Many Miles do you Have to Drive to Clear a Check Engine Light?

After clearing a car’s computer, you may only need to drive fifty to sixty miles, but one hundred miles seems to be the average for most vehicles. As you drive around, the vehicle’s computer will monitor every sensor and register the results.

Final Thoughts
