THINKDIAG HML is a smart Vehicle Communication Interface (VCI) designed for heavy-duty 12V/24V vehicles. It operates diagnostics on over 74 truck brands in collaboration with the THINKTOOL Series. Unlike the THINKDIAG 2, THINKDIAG HML requires THINKCAR tablet devices to function and cannot be used independently.

The THINKCAR THINKDIAG HML scanner tool adapter is a device that serves as a communication interface between your vehicle and the diagnostic tool. It reads the vehicle data and sends it to the diagnostic tool via Bluetooth, WIFI, or USB connection. The LED indicator on the device allows you to easily identify the working status of the module. This tool is ideal for mechanics who work on heavy-duty vehicles and require a simple yet powerful diagnostic tool.
