The Ideal Buyer’s Guide

There are various scanners out there and to choose the one that would meet all your needs, you need to do a bit of digging. To make this process of choosing a scanner easy for you, we have prepared the perfect buyers guide that will take into account all the factors that you need to consider.

OBD2 Scanner Buyers Guide

Bluetooth and Handheld

There are multiple kinds of scanners, but the most used ones are Bluetooth scanners and hand-held scanners. The Bluetooth scanners are the ones that connect wirelessly to your smartphone and you can carry out the diagnostics from there. The hand-held scanners, on the other hand, use a wired connection directly with the car. Both of these have their pros and cons which can be seen earlier in the article.

Scanning Tool Type

There are two types of OBD2 Car Scanning tools. You need to choose whether you require an OBD2 scan tool or an OBD2 code reader. Both of these serve their specific purposes, for instance, the OBD2 scan tool provides you with advanced troubleshooting information, whereas the OBD2 code reader can only read and clear codes from the car which has an OBD2 installed.


If you have selected a Bluetooth scanner, make sure it supports the operating system of your smartphone. Not all scanners support iOS. Mostly do support Android but as far as iOS is concerned, you need to confirm it before making the purchase.

Data Storage

Also, keep in mind the type of data storage the scanner supports and whether it meets your demand or not. For example, if you are a mechanic and have multiple cars to be checked, make sure you choose a scanner that has an organized data storage format.

Build QualityBrandLive FeedUser FriendlinessUpdates
You need to make sure that the scanner you buy is made up of satisfactory quality so it holds up for as long as possible, without you having to worry about changing it over and over again.

The build quality is also important because there are products out there that don’t work as advertised and have a shorter lifespan.

This factor is somewhat correlated with the next key factor which involves the brand which you ultimately choose.

Keep in mind that the brand is a very important factor when it comes to any sort of product.

Just make sure you buy from a reliable and a high rated brand so you get the most out of your scanner. A well-known brand that has confidence in its product normally offers a warranty as well for the buyer in case the product is not as advertised or if it has any other fault in it.

This means that buying a branded scanner would mean you don’t have to worry about it malfunctioning or not working at all. After all, it is quite some investment.

You need to make sure that you get yourself a scanner that supports live feed and readily gives the results so that they are as accurate and efficient as possible and it is easier for you to get to the root of the problem in your vehicle.
Before buying a scanner, just see how well you understand what the app or in the in-built screen displays and whether it is understandable for you, especially if you are a beginner.

In case you are a professional, you still need to keep in mind the user-friendliness.

In case you go for an in-built screen scanner, you need to consider the fact whether it receives software updates to make the device better and faster overtime or not.

If there are no updates, it is highly expected that the scanner gets outdated soon, because of the technological advancements in the automotive industry.

In a nutshell, it is not difficult to choose the most suitable scanner for your vehicle.

All you need to do is go through the buying guide and consider all the key factors before choosing your OBDII scanner.

After all, taking care of your vehicle and always having peace of mind that everything is fine and the vehicle is in perfect condition is a wonderful feeling.

Hence, to get the most out of your scanner and for your ease and comfort, make sure you do your complete research before choosing the final product as these scanners go as high as $100 and sometimes even more.

My Opinion – What do I suggest?

In my opinion, wired scanners are a better and more convenient option for professionals and enthusiasts as the results are more efficient and quicker as compared to wireless connections.

On the other hand, a wireless connection, via Bluetooth or WiFi, is a more suitable option for casual users as it is easy to use because of user-friendly application on the smartphone to show the results of the diagnostics.

That is all you need to know before you choose the best diagnostic tool for your vehicle or for your profession if it involves checking and regulating a lot of cars!

Frequently Asked Questions (FAQs)

Finally, here are some of the most asked question regarding the topic.

What is an OBD tool?

OBD stands for “On-Board Diagnostics” which is a vehicle’s built-in self-diagnostic system. It is found in many cars produced after 1996 in the USA as CARB made it mandatory for every vehicle after the recommendation of the Society of Automotive Engineers.

How does an OBD2 scanner work?

An OBD2 scanner is connected to your vehicle using a wired or a wireless connection and it scans the vehicle for any possible errors such as Malfunction Indicator Light popping up.

Once the scanner is connected to the 16 pin connector, it runs the diagnostics and shows the Diagnostic Trouble Codes (DTCs) which is the main problem that the car is facing, for instance, in the example given, it would briefly explain why the engine light has popped up.

Where is the OBD2 connector in the vehicle?

The OBD2 connector is located under the dashboard and can be often closed with a plastic cover with OBD written on it. It can also be found behind ashtrays or under the steering wheel. It is often covered, and often visible in plain sight.

It depends on the car you have. It varies from model to model and manufacturer to manufacturer. More or less, it is in the same position for every vehicle that is IBD2 compliant.

How to identify an OBD2 connector?

The OBD2 connector is a 16 pin connector that is found in all OBD2 compliant vehicles manufactured after 1996.

Oftentimes, there is a marking on the cover, if there is any, which clearly states OBD. Also, there is just one connector in that area where the OBD is found so you don’t have to worry about mixing it up with any other connector because there isn’t any.

What kind of errors can an OBD2 scanner detect?

The OBD2 scanner can detect a range of problems depending on the type of scanner you use. The errors may include check engine light, emissions and smog tests, etc.

There are several other errors that it detects as well and shows the Diagnostic Trouble Codes (DTCs) so that the user can identify what is the core of the problem and try and fix it.

How many types of OBD2 scanners are there?

OBD2 scanners are mainly of three types. Some are Bluetooth scanners that use third-party applications and a third-party device to help with the diagnostics.

Others include pc scanners which help with the diagnostics by a connection with a computer.

Lastly, the most professional ones are the hand-held scanners that you devices with in-built screens to display the diagnostics and have a wired connection with the car itself.

Does my car has OBD2 compatibility?

It was a mandatory standard in the USA for cars and light trucks to have OBD2 produced in 1996.

Later in 2001, it was made necessary for light gas cars and trucks in the EU to be OBD2 compliant. Similarly, in 2004, the EU made OBD2 mandatory in Diesel cars and light trucks. Finally, in 2005 and 2010, medium-duty and heavy-duty vehicles were made mandatory to be OBD2 compliant.

Hence, if you purchased the car according to these years, it is highly probable that your vehicle is OBD2 compatible.

Why is there a need for a diagnostic tool?

An OBD2 is a diagnostic tool for your vehicle which is more or less a need as well. It is because this simple and affordable device that can potentially help you save a lot of money and time.

It can even save you from the hassle of going to a mechanic over and over again for the slightest of issues in your vehicle. Many scanners also give live readings and regular reminders to keep your car in perfect health and everything updated.

These are only a few reasons to keep a diagnostic tool by yourself. Others may include the ability to inspect a vehicle before you purchase it, add or modify features of the car or even provide real-time data.


It is a one-time investment that can help you save money and time over several years.

So make sure you keep one of these portable and handy devices with yourself and make complete use of it.
