BCS OBD-II Bluetooth Diagnostic Interface ELM327 v1.5 for Android & Windows

Tap into your vehicle's onboard diagnostics with the BCS OBD-II Bluetooth interface, built around the proven ELM327 v1.5 chipset. It reads and clears fault codes, streams live sensor data, and supports all five OBD-II protocols — including CAN, KWP2000, ISO9141-2, J1850 VPW, and J1850 PWM — making it compatible with virtually any OBD-II compliant car or light truck sold in the US since 1996, or in the EU since 2001 (petrol) and 2004 (diesel).

Overview

The BCS-OB-2 plugs directly into your vehicle's 16-pin OBD-II port and pairs wirelessly with your Android phone, tablet, or Windows laptop via Bluetooth Class 2, giving you a stable connection up to 10 meters away. It draws less than 50mA from the port, so it won't drain your battery when the ignition is off. The compact ABS housing is built to withstand under-dash temperatures from -20°C to 70°C, and three LED indicators keep you informed of power, OBD data flow, and Bluetooth link status.
