Component Function Within System

When power is supplied from battery and receives control signal from the IPDM E/R, the LED headlight control module internally calculates the supplied power. The calculated power is distributed to multiple LEDs that consist of circuit boards and other components, illuminating the each lights.

When a malfunction is detected in the headlight (LO) circuit, the LED headlight control module outputs a headlight warning signal to the IPDM E/R (via LIN communication) to inform the driver of the malfunction.
