FUNCTION OF MAIN COMPONENTS
| Component | Function | |
|---|---|---|
| Headlight Dimmer Switch Assembly | Light Control Switch | The light control switch transmits a switch position signal to the main body ECU (driver side junction block assembly). |
| Main Body ECU (Driver Side Junction Block Assembly) | The main body ECU (driver side junction block assembly) receives the fog light switch signal from the light control switch and transmits a signal to the LED driver module (light control ECU). | |
| Fog Light Unit | Light Emitting Diode (LED) | The LED light shines ahead over a broader area, increasing the area visible to the driver. |
| LED Driver Module (Light Control ECU) | The LED driver module keeps a constant level of direct current applied to the LED, achieving stable LED illumination. | |
FUNCTION
The Light Emitting Diode (LED) fog light system consists of LEDs and LED driver modules.
SYSTEM CONTROL
LED Driver Module (Light Control ECU)
When the fog lights are turned on, the LED driver modules immediately turn on the LED (approximately 0.1 seconds). In addition, by regulating the output current flowing into the LED at a specified level, the LED driver modules prevent the light from getting brighter and dimmer due to voltage variation.
If malfunctions occur in the LED fog light system, the LED driver module turns off the LED.
