What is an ELM327 Bluetooth OBD2 Scan Tool?
An ELM327 Bluetooth OBD2 scan tool is a compact device that plugs into your vehicle’s On-Board Diagnostic (OBD) port. This port is typically located under the dashboard, near the steering column. Once connected, the ELM327 tool uses Bluetooth technology to wirelessly transmit diagnostic data to a smartphone or tablet running a compatible app.
