An On-board Diagnostic (OBD) scanner is a device that you can use to self-diagnose your vehicle or access vital information such as your vehicle’s VIN number, battery voltage, RPM, fuel efficiency, speed, and generic diagnostic codes among others.

The first OBD scanner was invented and used back in 1968 by Volkswagen, and through the years, different companies developed their own. The first types were non-standardized, and only in 1988 did standardized OBD scanners come. Until today, OBD scanners continue to evolve through different technological advancements and adapt to developments in the automotive industry. Nowadays, even remote OBD diagnostics is possible.

OBD Scanners can be used on almost all new cars produced after 1996, as newer cars come with universal connectors.

However, not all OBD scanners have the same level of compatibility. Some OBD Scanners can only be used for new daily drives and can’t process information from heavy diesel truckers.

With an OBD, you can perform tests yourself before or after acquiring a new car. On top of that, you will be able to check if the power-train control module of your vehicle is working, or its electronic control module(ECM), electric power steering (EPS), and even OE-level diagnostics for anti-lock braking systems (ABS), et cetera.

OBD scanners can also be used to keep your car safe. You can check if your airbags are still functional and even your seatbelt’s effectiveness. Lastly, you can even see in an OBD diagnostics whether a vehicle has been involved in an accident in the past or not.

Aside from that, OBD Scanners can also read a variety of problems in your system from transmission issues down to bad fuel efficiency. With an OBD scanner, you can determine whether a second-hand car that you’re looking to buy has been properly maintained in the past. This is important because car cosmetics and last-minute repairs can definitely hide the real condition of a car.

OBD2 Scanner Purchase Criteria

With all the different OBD2 brands there are today, picking out what is the best OBD scanner for your vehicle can be confusing for some.But don't worry, because this article is for that. Keep reading as we walk you through everything you need to know to help you decide which OBD scanner is best for you.

Double Check Compatibility

Since 1996, in the US, almost all production vehicles have been designed with universal connectors that are compatible with OBD-II scanners. The same goes for Canada in 1998, the European Union in 2004 and 2006 in Australia, Mexico, and New Zealand.

Before buying an OBD-II scanner, make sure that it’s compatible with your car. Not all cars made after the said years are compatible with all types of scanners and have different OBD connector pinouts from different manufacturers. It’s easier to read the description/manual of scanners before buying one than going through the process of returning one.

Your Mechanical Knowledge

OBD2 scanners both have basic and complex features making them a tool for both beginners and expert mechanics. If you’re only looking to buy an OBD2 scan Bluetooth tool only to read engine codes, it may not be worth the money. If you’re going to use an OBD2 scan tool because you’re performing advanced diagnostics on your vehicle, it sure is a necessary purchase, as this tool can be used to improve or maintain the performance of your car.

App Quality

All OBD2 Bluetooth scanners work in conjunction with an application on your device. To use the features of the scanner, you will have to access its UI in a mobile application. This means that the functionality and ease of use of a scanner depend on how user-friendly and responsive its application is. In most cases, scanners that come with decent applications in terms of UI design, functionality, and overall performance are rated higher.

Data Collection Capabilities

Look for a scanner that can do more than read check engine lights. There are some scanners out there that can only do the most basic diagnostics test but do not have the capability to perform advanced diagnostics for ABS and SRS systems. When choosing which OBD2 scanner is best, look for one with the most useful features.


In any type of product, you should always look at the warranty. An OBD-II scanner isn’t a daily use item, so it should last you a pretty long time, even ultimately outlasting your vehicle. It’s best if the OBD scanner of your choice has a lifetime warranty. You should also opt for scanners that have regular software updates, so you can stay in sync with changes in auto tech.


Of course, we’ll also be rating the scanners based on their prices. Is the total cost of the scanner justified by how many useful features it has? If a scanner is priced higher than the others but only has a few basic kits, then it should be scored lower. A scanner with a good balance between price and functionality gets a high score.

Frequently Asked Questions (FAQs)

No. You shouldn’t worry about OBD-II scanners damaging your car. Your cars were designed to be read by an OBD-II scanner. Just make sure that you’re properly connecting the scanner to your car with care.
Not likely. Running diagnostics tests on your vehicle with an OBD-II scan tool will not void your warranty.
Yes, performing the diagnostics test yourself and doing the repairs on your own can save you thousands of dollars if you have the mechanical know-how. You can buy an OBD2 scanner to check engine light codes, and with more advanced models, you can check your car’s whole system.
