As a car owner, you’re probably no stranger to the frustration of dealing with a mysterious check engine light or trying to diagnose a problem with your vehicle. That’s where an OBD2 scanner comes in – a powerful tool that can help you unlock the secrets of your car’s onboard computer and get to the bottom of any issues. But with so many OBD2 scanners on the market, it can be tough to know what to look for when buying one. In this article, we’ll take a closer look at the key features and factors to consider when selecting an OBD2 scanner that’s right for you.
Understanding OBD2 Scanners
Before we dive into the nitty-gritty of what to look for in an OBD2 scanner, let’s take a quick look at what these devices actually do. OBD2 stands for On-Board Diagnostics II, which is a standardized system that allows vehicles to communicate with external devices, such as scanners and code readers. An OBD2 scanner is essentially a device that plugs into your car’s OBD2 port (usually located under the steering column) and allows you to access a wealth of information about your vehicle’s systems and performance.
Types of OBD2 Scanners
There are several types of OBD2 scanners available, each with its own unique features and capabilities. Here are a few of the most common types:
- Basic Code Readers: These are the most basic type of OBD2 scanner and are designed to simply read and clear trouble codes. They’re usually inexpensive and easy to use, but may not offer much in the way of advanced features or functionality.
- Scan Tools: These are more advanced OBD2 scanners that offer a range of features, including live data streaming, freeze frame data, and advanced troubleshooting capabilities. They’re often more expensive than basic code readers, but offer a lot more value for serious DIYers and mechanics.
- Wireless OBD2 Scanners: These are OBD2 scanners that use Bluetooth or Wi-Fi to connect to your smartphone or tablet, allowing you to access your vehicle’s data remotely. They’re often more convenient than traditional wired scanners, but may require a separate app or software to function.
Key Features to Look for in an OBD2 Scanner
When shopping for an OBD2 scanner, there are several key features to look for. Here are some of the most important ones to consider:

What is an OBD2 Scanner and How Does it Work?
An OBD2 scanner is a device that connects to a vehicle’s onboard diagnostics system (OBD2) to retrieve information about the vehicle’s performance, trouble codes, and other data. It works by plugging into the vehicle’s OBD2 port, usually located under the steering column, and communicating with the vehicle’s computer system.
The scanner can read and display various types of data, including trouble codes, live sensor data, and freeze frame data. It can also perform functions such as clearing trouble codes, monitoring emissions, and testing vehicle systems. OBD2 scanners are commonly used by car owners, mechanics, and technicians to diagnose and repair vehicle problems.
What are the Different Types of OBD2 Scanners Available?
There are several types of OBD2 scanners available, including basic code readers, mid-range scanners, and advanced diagnostic tools. Basic code readers are simple devices that can read and display trouble codes, while mid-range scanners offer more advanced features such as live sensor data and freeze frame data. Advanced diagnostic tools are typically used by professional mechanics and technicians and offer a wide range of features and functions.
When choosing an OBD2 scanner, consider the level of functionality you need and the type of vehicle you own. If you’re a car owner who just wants to read trouble codes, a basic code reader may be sufficient. However, if you’re a mechanic or technician who needs more advanced features, a mid-range or advanced scanner may be a better choice.
