HBC WARNING LIGHT (AMBER)/HBC WARNING INDICATION/HBC INDICATOR LIGHT (GREEN)

id151300003800


Purpose


HBC indicator light (green)

•  The HBC indicator light (green) notifies the driver that the high beam control (HBC) system is operating.


HBC warning light (amber)/HBC warning indication

•  HBC warning light (amber)/HBC warning indication warns the driver that a malfunction is occurring in the high beam control (HBC) system.


Functions


HBC indicator light (green)

•  The instrument cluster turns the HBC indicator light (green) on based on the system conditions display request signal sent from the forward sensing camera (FSC) as a CAN signal.


HBC warning light (amber)/HBC warning indication

•  The instrument cluster turns on/displays the HBC warning light (amber)/HBC warning indication based on the the system malfunction display request signal sent from the forward sensing camera (FSC) as a CAN signal.


Structure/Construction

•  The HBC indicator light (green) and HBC warning light (amber) are built into the instrument cluster.
•  The HBC warning indication is displayed in the multi-information display.
•  A warning message is indicated in the center display when the HBC warning light (amber) is turned on. For the message content and verification method, refer to the [CENTER DISPLAY]. (See CENTER DISPLAY.)

Operation


HBC indicator light (green)

1.  When the high beam control (HBC) system operates, the forward sensing camera (FSC) sends (1) a system condition display request signal to the instrument cluster via CAN communication.
2.  The instrument cluster turns the transistor on (2) based on the system condition display request signal.
3.  When the transistor turns on, a ground circuit with the HBC indicator light (green) is established, and the HBC indicator light (green) turns on (3).

HBC warning light (amber)

1.  If there is a malfunction in the high beam control (HBC) system, the forward sensing camera (FSC) sends (1) a system malfunction display request signal to the instrument cluster via CAN communication.
2.  The instrument cluster turns the transistor on (2) based on the system malfunction display request signal.
3.  When the transistor is turned on, the HBC warning light (amber) turns on (3).

HBC warning indication

1.  If there is a malfunction in the high beam control (HBC) system, the forward sensing camera (FSC) sends (1) a system malfunction display request signal to the instrument cluster via CAN communication.
2.  The instrument cluster displays (2) an HBC warning indication in the multi-information display based on the system malfunction display request signal.
