Bluetooth Mini Box ELM327 OBD2 Scanner, White, Pro Edition

The white mini-box is the “Professional Edition” listing of this shop’s smallest Bluetooth scanner: the same 4.7 × 3.2 × 2.3 cm, 22 g body as its blue and black siblings, with the most complete documentation of the trio. Pair from an Android smartphone (password 1234), run Easy OBD2, ScanMaster ELM, DashCommand, OBD Auto Doctor or wOBD Crazy, and you get the whole scanner repertoire — trouble codes read and explained (3000+ generic definitions), MIL reset, and the live stream: RPM, load, coolant temperature, speed, fuel trims, manifold pressure, timing advance, intake air temperature, air flow, throttle position, O2 voltages and fuel pressure.

The electronics: 12 V operation with internal protection from short circuits and overvoltage, 45 mA nominal idle draw. The original listing’s warnings are worth keeping verbatim because they prevent bad purchases: this unit does not work on iOS — buy WIFI or Bluetooth 4.0 for iPhone; the adapter does not support all protocols, so check your car’s protocol before ordering and know that protocol-mismatch disputes are not accepted; the tool shows engine status rather than fixing anything; and you should know what OBD-II is and where the port lives before buying, plus be comfortable installing phone or Windows software.
