The selection boundary

This listing is included for its documented use context. It is not a hands-on test, best-price claim, rating claim, or performance guarantee.

What to know

It reads and clears standard OBD2 codes with a compatible app (app may cost extra); it does not diagnose the cause, and brand-specific modules (ABS/airbag on many makes) need higher tools.

Compatibility / use

Fits standard OBD2 ports (1996+ vehicles); Bluetooth pairing per the listing.
