KONNWEI OBD2 Diagnostic Meter

The KONNWEI OBD2 Diagnostic Meter KDIAG is a compact and reliable tool for reading and clearing diagnostic trouble codes (DTCs) from your vehicle's engine control unit (ECU). It supports all OBD2 protocols including CAN, ISO9141, KWP2000, and more, ensuring broad compatibility with most cars manufactured after 1996 in the United States. The device features a clear LCD display that shows live data such as engine RPM, coolant temperature, oxygen sensor readings, and fuel system status, helping you quickly identify issues.

Designed for ease of use, the KDIAG requires no external power source—it draws power directly from the OBD2 port. Simply plug it into your vehicle's diagnostic connector, turn the ignition on, and start scanning. The meter can also reset the check engine light after repairs. Its compact size makes it easy to store in your glove compartment. Whether you are a DIY enthusiast or a professional mechanic, this diagnostic meter provides essential functionality at an affordable price point.
