The Best OBD2 Scanner Automotive Diagnostic Tool

Cars comprise a myriad of components and sensors that work together. Vehicle owners and mechanics require tools that enable them to monitor the car's health without taking it apart. Consequently, all vehicles manufactured after 1996 have an inbuilt diagnostic system called the Onboard Diagnostics II (OBD2).

An OBD2 scanner allows the user to communicate with a car's advanced system and diagnose any faults. Since every vehicle uses the same platform, owners and mechanics have the freedom to choose a diagnostics scanner that fits their needs. If you want to figure out the best OBD2 scanner to buy, you need to understand the three types available on the market.

The 3 Types of OBD2 Scanners

1. Standard Code Readers

Primary code readers are the most affordable and easily accessible scanners available. They perform the most basic diagnostic operations that read the Diagnostic Trouble Codes (DTC) from your vehicle. These devices will often have a small screen that gives you data about the car's health and performance.

You can search the web for the meaning of the information you get from these tools. The gadget gives you an option to clear any error code that you have fixed. Also, they come in both wireless and wired options.

2. Professional OBD2 Scan Tools

Professional OBD2 scan tools are fully equipped to interface with any vehicle and perform any number of diagnostic operations. The devices will have plenty of connectors, along with Engine Control Unit programming features and adaptations.

Moreover, a professional OBD2 scan tool is capable of saving data and displaying information using graphs. Hence, you can make comparisons and judgments about various performance metrics of your vehicle. Admittedly, the expert tools have hefty price tags.

3. DIY Scanners

These tools have more advanced features than the basic models, but they are pricier. Most of these auto scanners do not come with displays, and so you need to connect them to a phone or computer via Bluetooth to get your vehicle information.

The interface with an external device gives you more options, such as viewing live data for monitoring your car. This type of OBD2 scanner gives DIY mechanics a more capable tool for taking care of their car.
