FRONT COMBINATION LIGHT
id091800010200
Purpose
• The front combination light groups and houses together the parts related to the front exterior lights such as the headlight, running light, parking light, front turn light, headlight leveling actuator, swivel actuator, wiring harnesses, and connectors.
• Energy consumption reduction and maintenance-free design been achieved with the adoption of LEDs on the headlights LO, HI, running light (LED type), parking light (LED type), and front turn light.
• Visibility of road signs positioned higher up has been improved by blurring the cut lines of the headlights between light and dark to the extent possible.
• Long distance visibility of pedestrians and roadside zones and short distance visibility during poor weather conditions such as rain and fog have been improved by expanding the light distribution of the headlights.
Function
• Each light illuminates or flashes when the light switch, turn switch, or hazard warning switch is operated.
Structure/Construction
• The front combination light groups the parking light/running light bulb. (With parking light/running light (bulb type))
• The front combination light is integrated with the following parts:
Parking light/running light (bulb type)
-
― Headlight HI/LO (LED)
― Front turn light (LED)
― Headlight leveling actuator
Parking light/running light (LED type) (with adaptive front lighting system (AFS))
-
― Headlight HI/LO (LED)
― Front turn light (LED)
― Parking light/running light (LED)
― Headlight leveling actuator
― Swivel actuator
Parking light/running light (LED type) (with adaptive LED headlights)
-
― Headlight HI/LO (LED)
― Front turn light (LED)
― Parking light/running light (LED)
― Side-illuminating LED (LED)
― Headlight leveling actuator
• A projector type headlight has been adopted for the headlight HI/LO.

Note
-
• Fogging or condensation on the inside of the front combination lights may occur, however, it is a natural phenomenon occurring as a result of a temperature difference between the interior and exterior of the front combination lights and has no effect on the light performance.
• Fogging or condensation occurring as a natural phenomenon will dissipate when the temperature inside the front combination lights rises after the headlights are illuminated and a period of time has elapsed.
• Heat generated by the illumination of the LEDs is absorbed and dispersed by the heat radiation plates installed to the back of the headlight HI/LO reflectors.
• The optimized shape of the headlight LO and HI reflectors emits light over a wide area.
Operation
Headlight LO
1. When the light switch is moved to the HEAD position and the dimmer switch is moved to the LO position, the start stop unit detects (1) a headlight LO signal.
2. The start stop unit sends (2) the headlight LO signal to the front body control module (FBCM) via CAN communication.
3. When the front body control module (FBCM) receives the headlight LO signal with the ignition switched ON (engine off or on), it turns (3) the headlight LO relay on.
4. When the headlight LO relay turns on, the headlight LO is illuminated (4).
Headlight HI
-
Without adaptive LED headlights
-
1. When the light switch is moved to the HEAD position and the dimmer switch is moved to the HI position, the start stop unit detects (1) a headlight LO signal and headlight HI signal.
2. The start stop unit sends (2) the headlight LO signal and headlight HI signal to the front body control module (FBCM) via CAN communication.
3. When the front body control module (FBCM) receives the headlight LO signal and headlight HI signal with the ignition switched ON (engine off or on), it turns (3) the headlight LO relay and headlight HI relay on.
4. When the headlight LO relay and headlight HI relay turn on, the headlight LO and headlight HI are illuminated (4).

With adaptive LED headlights
-
Flash-to-pass
1. When the dimmer switch is moved to the FLASH-TO-PASS position, the start stop unit detects (1) a FLASH-TO-PASS signal.
2. The start stop unit sends (2) the FLASH-TO-PASS signal to the front body control module (FBCM) via CAN communication.
3. When the front body control module (FBCM) receives the FLASH-TO-PASS signal with the ignition switched ON (engine off or on), it turns (3) the headlight LO relay and headlight HI relay on.
4. When the headlight LO relay and headlight HI relay turn on, the headlight LO and headlight HI are illuminated (4).
Parking light
1. When the light switch is moved to the TNS (parking lights) position, the start stop unit detects (1) a TNS (parking lights) signal.
2. The start stop unit sends (2) the TNS (parking lights) signal to the front body control module (FBCM) via CAN communication.
3. When the front body control module (FBCM) receives the TNS (parking lights) signal, it turns (3) the TNS relay on.
4. When the TNS relay turns on, the parking light is illuminated (4).
Front turn light
-
Turn light system
-
1. When the turn switch is moved to the LH or RH position, the start stop unit detects (1) a turn switch LH signal or turn switch RH signal.
2. The start stop unit sends (2) the turn switch LH signal or turn switch RH signal to the front body control module (FBCM) via CAN communication.
3. When the front body control module (FBCM) receives the turn switch LH signal or turn switch RH signal with the ignition switched ON (engine off or on), it flashes (3) the front turn light (LH) or front turn light (RH).
-
Hazard warning system
-
1. When the hazard warning switch is turned on, the start stop unit detects (1) a hazard warning switch on signal.
2. The start stop unit sends (2) the hazard warning switch on signal to the front body control module (FBCM) via CAN communication as a turn switch LH signal and turn switch RH signal.
3. When the front body control module (FBCM) receives the turn switch LH signal and turn switch RH signal, it flashes (3) the front turn light (LH) and front turn light (RH).
