How to choose:
• Quick checks & live data → compact Bluetooth/Wi-Fi dongle + your favorite app.
• Workshop & multi-brand → handheld scanner with on-device menus, graphing & service resets.
• Brand-specific features → choose a model that lists your make/year for ABS/SRS/TPMS & coding/adaptations.

Setup tips: Plug into the OBD-II port (usually under the dash), turn ignition to ON, pair via Bluetooth/Wi-Fi, select the correct vehicle profile, then scan. Do not leave dongles inserted if the car sits for long periods.

*Advanced functions vary by vehicle and scanner/app. Always verify compatibility for your make, model, and year.
