OBD2: FAQ

How do I ensure the scanner works with my car model?

Check the protocol support list in the product description, specifically looking for CAN-BUS or J1850. Most AliExpress sellers provide a detailed vehicle coverage list; always confirm your car's manufacturing region and engine type.

How can I tell if an ELM327 scanner is high quality?

Look for the PIC18F25K80 chipset mentioned in the technical specs, as it offers the highest stability and command support. Avoid ultra-cheap versions that lack the full instruction set required for advanced diagnostic apps.

What is the difference between a basic reader and a professional tool?

Basic readers only clear engine codes, while professional AliExpress tools offer multi-system diagnostics like Airbag, ABS, and Transmission. Check for 'Bi-directional control' if you need to perform active tests on car components.

Will the scanner arrive safely given its sensitive electronics?

Reputable sellers use anti-static bags and hard-shell carrying cases to protect the internal circuitry during transit. Choose AliExpress Standard Shipping for better tracking and specialized handling of electronic diagnostic equipment.
