An OBD-II scanner is a need for any car owner. The most fundamental use for these tools is to read and erase engine fault codes from your car's onboard diagnostics system. To further aid in diagnosis, OBD-II scanners can, depending on the model chosen, read fault codes from numerous vehicle systems, display the current state of the vehicle's operation, and more. Choosing the right scanner can seem like a daunting task when you're just starting out. Even if you know the features you want, it can be equally as difficult to figure out which models are worth your money. I hope that the information I give you here will make using an OBD-II scanner a breeze.

Buying Guide

Vehicle Compatibility 

Obviously, you need to make sure that the scanner you're looking at is compatible with your car. The first step is to determine whether or not the device is compatible with your car or whether or not it can connect to your car. Don't rush into buying a scanner without first making sure it'll be compatible with your automobile and any future vehicles you might want to purchase. While this is more of a problem for those who drive luxury vehicles or those from Europe in general, it's always a good idea to double-check whether or not your automobile is compatible with a particular accessory.


However, some scanners can do much more than merely read engine codes. It is possible to interpret engine, gearbox, and anti-lock brake system (ABS) codes with the help of others. Then there are models that can not only read these codes but also run diagnostics on the car's various systems, letting you know whether or not the electrics are in excellent shape. If you only plan on making simple fixes, you can save money by forgoing the more advanced features of a scanner. These features are optional for simple tasks, but essential for more complex ones or expert auto maintenance.

Connection Type

A wired connection is preferred by most OBD-II scanners for a number of reasons. The most significant benefit is that the tools may usually use the vehicle's electricity for operation, eliminating the need for additional batteries in some circumstances. If this is something you'd rather avoid, or if you just like the convenience of scanning codes from a distance, a wireless unit may be worth considering. There is no need to switch between tools because some of them, like the BlueDriver Pro OBD-II Bluetooth Car Diagnostic Scan Tool, can transmit data to your smartphone.

Wired Vs. Bluetooth

Consider an OBD2 scanner with Bluetooth capability if you want the best one. Wireless scanners are becoming increasingly popular due to their convenience and capacity for data collecting, especially given the fact that having a physical cord usually requires you to remain in close proximity to the car while doing a diagnosis.

If your smartphone has Bluetooth and the scanner has an accompanying app, you can review the information on the go.

This is a great choice for those who want a hands-off diagnostic system that collects data while they drive, but it also gives them access to the engine compartment in case they need to check something. The ideal OBD2 scanner for your profession depends depend on how much data you require, while some high-end models include internal batteries that last for hours.

Vehicle Make

Even though many OBD2 codes are recognized by all vehicles, many others are not. Every vehicle also has its own unique set of error codes that are peculiar to its manufacturer. The most advanced OBD2 readers are compatible with the majority of popular makes. Check the manufacturer's website to see if your OBD2 scanner can read error codes for the vehicle(s) you intend to use it with.

Live Data

In order to figure out what's going on with your car, real-time data might be quite helpful. They can detect the number of misfires in a cylinder, as well as the volume of air entering the engine.

This information can help you diagnose issues beyond what the check engine light indicates if you know what you're searching for. Even the most seasoned mechanics will need to double-check their work before ordering replacement parts, but they can usually identify the source of the problem using real-time data and the engine code.

Transmission/SRS/ABS Scanning

The systems on your car go well beyond the ones indicated by the check engine light. In contrast to a basic OBD2 reader, which can only read engine codes, a more sophisticated reader can read data from all of your car's systems.

A gadget that checks all systems can save you in the long run, even if the check engine light is the only indicator that something is wrong.

It's also not too difficult to locate a tool that can examine every system, as this is typically one of the first functions manufacturers include.

Troubleshooting Tips

It doesn't matter if you're brand new to fixing cars or a seasoned pro; you'll eventually encounter a problem that stumps you. This is why there are so many resources available, such databases full of information to help you solve issues.

Some scan programs, however, will grant you access to these databases, sometimes at no cost at all, even though many of them restrict access to their content behind paywalls. Better yet, several scan tools can input your vehicle's data and problems automatically and point you in the appropriate direction.

This means less hours spent seeking for answers and quicker maintenance. It's a helpful resource to have on hand whenever you find yourself at a loss for an answer or even if you just want to double-check your suspicions.


When Do You Need an OBD2 Scan Tool?

An OBD2 scan tool can interpret the meaning of a trouble code if your car's check engine light comes on. Although an OBD2 scan tool will read the check engine light, it will not read transmission, ABS, or SRS fault codes.

While these features are available on some OBD2 scan equipment, they are an extra, not a requirement.

What Vehicles Are Compatible with an OBD2 Scan Tool?

OBD2 can be used with any car manufactured after January 1, 1996, and sold in the United States. That's because OBD2 compatibility has been mandatory for all US-sold vehicles since January 1, 1996.

If a car was produced after September 16, 1996, and it is sold in the United States, then it has OBD2 because automakers don't want to produce variants for different markets.

Are OBD scanners worth it?

An OBD2 scanner is useful for checking a vehicle's diagnostic trouble codes and doing other routine maintenance tasks at home. It's true that not all auto repair shops provide complimentary diagnostic services.

Are all OBD scanners the same?

The majority of diagnostic equipment for automobiles do things like reading error codes and programming the ECU (ECU). Different products have varying degrees of success in erasing error codes from various auto systems. Furthermore, some equipment may only be compatible with OBD1 connections, which are used in older automobiles.


It can be quite difficult to repair your automobile without the proper equipment. However, if you have the proper equipment, you can finish the task at hand and move on with your life. The BlueDriver Bluetooth Scanner is an excellent choice for DIY mechanics who have access to a smartphone, while an Autel is the best option for garage owners.

You can't top the convenience and efficiency of those gadgets, albeit they aren't without their own merits. What are you waiting for, then? Get an OBD2 scanner and you can fix your car in no time.
