Buying Guide
Code Reading and Clearing Capabilities
The primary job of any diagnostic scanner is to read and delete trouble codes. Look for a model that supports all OBD2 protocols and can access multiple systems like the engine, transmission, ABS, and SRS. A scanner that reads generic and manufacturer-specific codes gives you a fuller picture. The best units also provide clear definitions so you know what each code means before you clear it.

Vehicle Compatibility and Coverage
Not every scanner works with every car. Check the vehicle coverage before buying. Some scanners support hundreds of makes and models, while others are limited to specific regions or years. Modern tools often cover vehicles from 1996 onward. If you work on a mix of American, European, and Asian cars, choose a scanner with broad compatibility. The Autel and ANCEL models in this roundup cover thousands of vehicles, but always verify with your VIN if you are unsure. Our autel MaxiIM IM508S pro review covers another solid option.
Ease of Use and Display
A clear screen and intuitive interface save time and frustration. Look for a touchscreen display that shows live data in graphs, text, or charts. Auto-scan features can identify your vehicle and scan all systems with one press. Wireless connectivity lets you move around the car while diagnosing. These features make the process faster, especially when you are under the hood or on the driver side. For an in-depth review of another popular model, see our TOPDON AD500 OBD2 scanner review.
Additional Features and Service Functions
Many modern scanners do more than just read and delete codes. They offer service functions like oil reset, ABS bleeding, battery registration, and throttle calibration. These extras turn a simple code reader into a full diagnostic tool. If you plan to perform maintenance tasks, invest in a scanner with these capabilities. Bidirectional active tests let you command components to verify repairs before replacing parts. This saves money and time. For more on TPMS tools, check our autel MaxiTPMS TS501 pro review.

Frequently Asked Questions
Can any OBD2 scanner delete codes?
Most OBD2 scanners can clear or delete trouble codes, but the capability varies by model. Basic code readers may only erase generic engine codes, while advanced scanners can clear codes from multiple systems like ABS, SRS, and transmission. Always check the specifications to ensure it meets your needs.
Will deleting a code fix the problem?
No, deleting a code only turns off the warning light. The underlying issue remains until you repair the faulty part or system. Use the scanner to identify the root cause, fix it, then clear the code to verify the repair was successful.
Do I need a bidirectional scanner to delete codes?
No, you do not need a bidirectional scanner just to delete codes. A standard OBD2 code reader can read and clear trouble codes. However, bidirectional scanners add active tests that help confirm repairs, making them a better long-term investment for DIYers and professionals.
How often should I update my scanner’s software?
It depends on the brand and model. Some scanners offer lifetime free updates, while others require annual subscriptions. Updating regularly ensures compatibility with newer vehicle models and access to the latest features. Check the product details before buying to understand update policies.
