ELM327 Mini OBDII Bluetooth Diagnostic Interface Car Scanner
The ELM327 Mini OBDII Bluetooth Diagnostic Interface is a compact, plug-and-play dongle that transforms your smartphone or PC into a vehicle diagnostic tool. Simply plug it into the vehicle’s OBD-II port (usually under the dashboard), pair via Bluetooth, and you can instantly access many of the car’s onboard diagnostics. This small adapter acts as a translator between the car’s electronic control unit (ECU) and your device, allowing for reading engine and sensor data, retrieving fault codes, and interpreting them in a human-readable way.
Once connected and paired, the ELM327 interface enables real-time reading of a wide range of vehicle parameters engine RPM, coolant temperature, fuel system status, vehicle speed, and many other live sensor outputs. It also allows retrieval of stored Diagnostic Trouble Codes (DTCs), both generic and manufacturer-specific, to help identify issues. When problems are resolved, the tool can clear the codes and reset the “Check Engine” (MIL) light, giving you immediate feedback and insight into the state of your vehicle without the need for a full diagnostic shop.
Because the ELM327 is Bluetooth-enabled, it works wirelessly with Android phones and Windows PCs (some apps may also run on other platforms), turning your device into a full-featured diagnostic console. Its small size makes it unobtrusive and easy to leave connected or store in the glovebox. For car owners, DIY enthusiasts, or mechanics, it’s a cost-effective, accessible tool to perform basic to intermediate diagnostics, monitor performance, and handle troubleshooting all without bulky or expensive scan tools.
Features:
- Supports multiple OBD-II protocols (CAN, ISO9141, ISO14230 (KWP), J1850 PWM/VPW) for broad vehicle compatibility.
- Reads both generic and manufacturer-specific diagnostic trouble codes (DTCs), with a large database of definitions.
- Retrieves real-time sensor and performance data (engine RPM, coolant temperature, vehicle speed, fuel trims, etc.).
- Clears error codes and resets the check-engine/MIL light after repair or diagnostics.
- Wireless Bluetooth connectivity works with Android phones and Windows PCs for convenient diagnostics without cables.
- Small, compact form factor minimal intrusion, easy to plug in and store.
