Before you buy
Frequently asked questions
What is an OBD2 scanner?
An OBD2 scanner is a diagnostic tool that connects to your car’s onboard computer via the OBD2 port. It reads trouble codes that indicate issues with the engine, transmission, emissions, and other systems.
Do I need a professional-grade scanner for my home garage?
Not necessarily. Many affordable scanners can read and clear codes and show live data, which is enough for most DIY repairs. Professional-grade scanners offer advanced functions like coding and programming, which are rarely needed by home mechanics.
Can an OBD2 scanner tell me exactly what’s wrong with my car?
It can give you the trouble code and a description, but it does not pinpoint the exact faulty part. For example, a code may indicate a misfire, but you still need to determine if the spark plug, coil, or fuel injector is the culprit. Some scanners and apps provide likely fixes based on common causes.
Are all OBD2 scanners compatible with all cars?
All OBD2 scanners work with any vehicle that is OBD2 compliant, which includes most cars sold in the US since 1996. However, some scanners have enhanced capabilities for certain manufacturers, like Ford, GM, or Toyota. Check the product details for specific compatibility.
What is the difference between generic and manufacturer-specific codes?
Generic codes (e.g., P0300) are standardized across all makes and models. Manufacturer-specific codes (e.g., P1234) are unique to a brand and provide more detailed information. Many scanners read both, but some budget models may only show generic codes.
Do I need a Wi-Fi or Bluetooth scanner?
No. Many excellent scanners have built-in screens and don’t require a phone. Bluetooth and Wi-Fi scanners are convenient if you prefer using your smartphone’s larger screen and apps, but they add complexity. Choose based on your preference.
Can I use an OBD2 scanner to check my car’s battery?
Some scanners, like the Autel AL619 and LAUNCH CRP123X, include a battery test function that can check the battery’s state of charge and health. However, a dedicated battery tester may be more accurate.
How often should I update my OBD2 scanner?
It’s recommended to update your scanner at least once a year or when you encounter a code that isn’t recognized. Updates often include new definitions and bug fixes. Many scanners offer free lifetime updates, while others require a subscription.
Can an OBD2 scanner clear the check engine light?
Yes, most OBD2 scanners can clear diagnostic trouble codes and turn off the check engine light. However, if the underlying issue persists, the light will come back on. Always address the root cause before clearing codes.
Are there any OBD2 scanners that work with diesel vehicles?
Many OBD2 scanners work with diesel vehicles, especially those that are OBD2 compliant. However, some diesel-specific issues may require a scanner with enhanced diesel functions. Check the product description for diesel compatibility if you own a diesel car or truck.
Our pick
For most home garages, the Ancel AD410 offers the best combination of price, features, and usability. It covers essential diagnostics and is easy to operate. If you need ABS and SRS scanning without breaking the bank, the Autel AutoLink AL619 is a strong alternative. For those who want a professional-grade tool with all the bells and whistles, the Autel MaxiCOM MK808Z is worth the investment.
