KONNWEI KW902 Bluetooth OBD2 Scanner, Wireless ELM327 Diagnostic Adapter

The KW902 OBD-II Diagnostic Scanner is a compact vehicle diagnostic adapter that plugs directly into your car’s OBD-II port. It is powered by the vehicle’s diagnostic socket, so no batteries or extra cables are required. Its stable wireless connection and automatic sleep mode—activated after around 30 minutes without communication—make it convenient for everyday vehicle monitoring.

It supports all standard OBD-II protocols and uses a fast, reliable ARM chip for responsive diagnostics. Use it to read and erase fault codes, view code descriptions, switch off the Check Engine/MIL warning after the underlying issue has been resolved, and monitor live vehicle data.

Live information may include vehicle speed, engine load, coolant temperature, oil pressure, intake-manifold pressure, throttle position, oxygen-sensor readings, intake-air temperature, and fuel-consumption data. The device can also log parameters, display real-time graphs, and export data for later viewing or printing, depending on the compatible diagnostic app used.

To use, locate your vehicle’s OBD-II port—usually beneath the driver-side dashboard near the steering column—plug in the adapter, turn the ignition to ON without starting the engine, then connect through a compatible diagnostic application to read or clear supported codes.
