Different Types of Scan Tools for Car
Understanding the different types of scan tools for car diagnostics is crucial for choosing the one that best suits your needs. Here are the most common types:
OBD-II Code Readers
These are basic scan tools for car diagnostics, primarily designed to read and clear diagnostic trouble codes (DTCs). They are a great entry-level option for DIYers and car owners looking for a quick and easy way to understand why their check engine light is on. OBD-II code readers are typically affordable and easy to use.
Handheld Scan Tools
Handheld scan tools offer more advanced features than basic code readers. They can provide live data streams, allowing you to monitor various sensor readings in real-time. They also offer more detailed diagnostic information, such as freeze frame data and the ability to perform some bidirectional control tests. Handheld scan tools are ideal for car enthusiasts and DIY mechanics who want more diagnostic capabilities.
Professional-Grade Scan Tools
Professional-grade scan tools are the most comprehensive diagnostic tools available. They offer a wide range of advanced features, including programming capabilities, module coding, and access to manufacturer-specific diagnostic information. These tools are typically used by professional technicians and are significantly more expensive than basic code readers and handheld scanners.
Factors to Consider When Choosing a Scan Tool for Car
Choosing the right scan tool for car diagnostics depends on several factors, including your budget, technical expertise, and diagnostic needs.

Scan tools range in price from a few tens of dollars for basic code readers to thousands of dollars for professional-grade tools. Determine how much you are willing to spend and look for tools within your price range.
