FRONT TURN LIGHT/PARKING LIGHT
id091800705900
Purpose
• The front turn lights are used to signal vehicles/people at the front of the vehicle that the vehicle is going to make a right or left turn.
• The parking lights are used to signals the presence of the vehicle to vehicles/people at the front during nighttime.
Function
• Each light illuminates or flashes when the light switch, turn switch, or hazard warning switch is operated.
Structure/Construction
• Front turn lights/parking lights built into the front bumper have been adopted.
• LED type front turn lights/parking lights have been adopted.
Operation
Parking light
1. When the light switch is in the TNS (parking lights) position, the instrument cluster detects (1) a TNS (parking lights) signal.
2. The instrument cluster sends (2) the TNS (parking lights) signal to the body control module (BCM) via CAN communication.
3. When the body control module (BCM) receives the TNS (parking lights) signal, it sends (3) a TNS (parking lights) on request signal to the light control module via CAN communication.
4. When the light control module receives the TNS (parking lights) on request signal, it turns the parking lights on (4).

Turn light system
-
1. When the turn switch is in the LH or RH position, the instrument cluster detects (1) a turn switch LH signal or turn switch RH signal.
2. The instrument cluster sends (2) the turn switch LH signal or turn switch RH signal to the body control module (BCM) via CAN communication.
3. When the body control module (BCM) receives the turn switch LH signal or turn switch RH signal with the main power switched ON (READY off or on), it sends (3) a turn light (LH) flash request signal or turn light (RH) flash request signal to the light control module via CAN communication.
4. When the light control module receives the turn light (LH) flash request signal or turn light (RH) flash request signal, it flashes (4) the front turn light (LH) or front turn light (RH).

Hazard warning system
-
1. When the hazard warning switch is turned on, the climate control unit detects (1) a hazard warning switch on signal.
2. The climate control unit sends (2) the hazard warning switch on signal to the body control module (BCM) via CAN communication.
3. When the body control module (BCM) receives the hazard warning switch on signal, it sends (3) a turn light (LH) flash request signal and turn light (RH) flash request signal to the light control module via CAN communication.
4. When the light control module receives the turn light (LH) flash request signal and turn light (RH) flash request signal, it flashes (4) the front turn light (LH) and front turn light (RH).
