The OBD2 Multi-Function Display utilizes the Controller Area Network (CAN / CAN bus) to rapidly retrieve real-time vehicle data from the ECU. Equipped with a 16MHz processing core, it ensures high-speed and accurate data presentation. Featuring a plug-and-play design, it offers quick installation with no modification to the vehicle’s wiring required.

The high-contrast OLED screen provides excellent visibility under all lighting conditions. Users can customize multiple warning thresholds for key metrics such as coolant temperature, oil temperature, exhaust temperature, and boost pressure. When any monitored value exceeds the set limit, the system immediately triggers visual flashing and an audible buzzer alert—allowing drivers to detect potential issues early, respond in time, and enhance driving safety and vehicle awareness.
