Bluetooth OBD2 Car Diagnostic Scanner – ELM327 Auto Code Reader

Bluetooth OBD2 Car Diagnostic Scanner – ELM327 Auto Code Reader

Easily monitor your car’s health with this Bluetooth OBD2 Car Diagnostic Interface Scanner (ELM327). Designed to connect directly to your vehicle’s OBD-II port, this compact device provides real-time diagnostics via your smartphone, tablet, or PC.

It supports multiple OBD-II protocols (including ISO9141, ISO14230, and ISO15765 CAN), making it compatible with most cars worldwide. With built-in short-circuit and overvoltage protection, it ensures safe and reliable operation.

This smart scanner reads and clears error codes, turns off the Check Engine Light, and provides live sensor data such as RPM, fuel status, intake air temperature, coolant temperature, throttle position, fuel pressure, and more.

Perfect for DIY car owners, mechanics, and anyone who wants to save time and money on vehicle diagnostics.
