Frequently Asked Questions
What is a car OBD2 scanner?
An OBD2 scanner is a diagnostic tool that connects to your vehicle’s onboard computer via the OBD2 port (usually under the dashboard).
It reads diagnostic trouble codes (DTCs) and can display live data, helping to identify issues with the engine, transmission, emissions, and other systems.
Will any OBD2 scanner work with my car?
Most scanners work with cars manufactured after 1996 in the US. However, some luxury or Asian vehicles may require specific protocols. For broader compatibility, consider a scanner that supports multiple protocols. Our guide to OBD2 scanners for Asian vehicles covers specialized options.
Do I need a subscription for an OBD2 scanner?
Most basic and mid-range scanners do not require a subscription. Some advanced models (like BlueDriver) initially charged for premium features but have since moved to no-subscription models. Always check the product description before purchasing. For subscription-free options, see our recommendations for home mechanics.
Can I use a Bluetooth OBD2 scanner with my iPhone or Android?
Yes, most Bluetooth scanners are compatible with both iOS and Android. Look for models that support both platforms or a dedicated app. Our best iOS OBD2 scanner guide and best Android OBD2 scanner guide can help you choose the right one for your device.
How do I reset the check engine light with an OBD2 scanner?
After diagnosing and fixing the issue, most scanners have a “Clear Codes” or “Erase” function. Simply select it, and the scanner will reset the check engine light.
However, if the underlying problem isn’t fixed, the light will return after a few drive cycles. For step-by-step instructions, refer to your scanner’s manual.
What is the difference between a code reader and a scan tool?
A code reader simply retrieves DTCs and may clear them. A scan tool offers more advanced features like live data, bidirectional control, and system-specific diagnostics (ABS, SRS, etc.). Professionals and serious DIYers typically prefer scan tools. Our professional OBD2 scanner picks can guide you.
