Bluetooth Mini Dome ELM327 OBD2 Scanner, White

The white dome is the same scanner as its blue and black siblings under the shell: an ELM327 processor in a pocket-format body that pairs over Bluetooth Classic to Android phones and Windows laptops. Read generic and manufacturer-specific trouble codes — more than 3000 generic definitions in the database — see what each means, clear them, and watch the check-engine light go out instead of paying a shop just to tell you the gas cap was loose.

Live sensor data streams the full everyday set: RPM, calculated load, coolant temperature, vehicle speed, fuel system status, short- and long-term fuel trim, intake manifold pressure, timing advance, intake air temperature, air flow rate, throttle position, oxygen sensor voltages and fuel pressure. The white shell earns its keep in practice — against a dark footwell it is the version you actually find when you need it. Honest boundaries as for the whole dome family: no Nissan compatibility, and no iOS pairing — iPhone and iPad users need the WIFI or Bluetooth 4.0 variants.
