SIDE TURN LIGHT

id091800706000


Purpose

•  The side turn lights are used to signal vehicles/people at the side of the vehicle that the vehicle is going to make a right or left turn.

Function

•  When the body control module (BCM) receives a turn switch LH signal or turn switch RH signal sent via CAN communication from the instrument cluster, it flashes the side turn light.

Structure/Construction

•  Side turn lights built into the power outer mirrors have been adopted.
•  LED type side turn lights have been adopted.

Operation


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 ignition switched on (engine off or on), it sends (3) a turn light (LH) flash request signal or turn light (RH) flash request signal to the door-electrical supply unit via CAN communication.
4.  When the door-electrical supply unit receives the turn light (LH) flash request signal or turn light (RH) flash request signal, it flashes (4) the side turn light (LH) or side 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 door-electrical supply unit via CAN communication.
4.  When the door-electrical supply unit receives the turn light (LH) flash request signal and turn light (RH) flash request signal, it flashes (4) the side turn light (LH) and side turn light (RH).
