The Konnwei KW340 is a reliable and comprehensive OBDII/EOBD diagnostic scanner, designed for immediate detection and resolution of engine problems. With a 2.8" color display and an ergonomic design in red-black color, it allows reading and clearing of fault codes (DTC), deactivation of the Check Engine light, and viewing of live sensor data.
It is compatible with gasoline and diesel vehicles from 1996 onwards, while also offering additional battery check functions and one-click checks for maximum speed in diagnosis.
The KW340 connects directly to the vehicle's OBD2 port and provides access to the ECU data in real time. It allows you to read and clear fault codes (DTC), helping you identify the reason why the Check Engine (MIL) light is on.
After repairs, you can reset the faults, clearing the warning indicator on the dashboard. It is the ideal tool for preparing your vehicle before inspection, ensuring that the emissions system is functioning properly.
The large 2.8-inch LCD color screen offers excellent clarity for reading data, while the three bright LED indicators provide instant visual updates on the vehicle’s status.
The Green light indicates that all systems are fine, the Yellow warns of pending faults, and the Red indicates the presence of a serious malfunction. This combination makes diagnosis simple and understandable even for non-professional users.
Time is valuable in diagnostics, which is why the Konnwei KW340 features One-click buttons for the most common functions. With just one press, you can perform an I/M Readiness check for emissions readiness, view the fault code (DTC), read the vehicle identification number (VIN), or quickly check the battery status. This ease of use speeds up the inspection process for cars, SUVs, and light commercial vehicles.
Beyond fault diagnosis, the KW340 offers the Battery Voltage Waveform Test function, which displays the fluctuation of the battery voltage in a graph. This helps in assessing the health of the battery and the alternator charging system.
Additionally, the Live Data Stream function allows you to monitor in real time the values of engine sensors, such as RPM, coolant temperature, and pressure, providing a complete picture of the vehicle's operational status.
The device supports all modern communication protocols, including OBDII, EOBD, and CAN. It is compatible with most gasoline and diesel vehicles manufactured from 1996 onwards for the US market, and from 2000 (gasoline) / 2004 (diesel) for Europe.
It is powered directly from the OBD2 port (DC 8-18V), so it never needs charging or internal batteries, making it always ready for use in case of need.
Made from durable ABS plastic in red and black color, the KW340 is designed to withstand workshop conditions. The package is complete and includes the diagnostic unit with an integrated 85cm cable, a USB Type-C cable for future upgrades, and a detailed user manual.
Weighing only 0.229kg and with compact dimensions, it is the essential gadget that every driver should have in their car's glove compartment for safety and prevention.
