What is an OBD2 Bluetooth ELM327 App?

An OBD2 (On-Board Diagnostics II) Bluetooth ELM327 app works in conjunction with a small, inexpensive hardware device – the ELM327 adapter.

The adapter communicates with your car’s computer, reading diagnostic trouble codes (DTCs), sensor data, and other information. This data is then transmitted wirelessly via Bluetooth to your smartphone or tablet, where the obd2 bluetooth elm327 app displays and interprets it.
