HBC INDICATOR LIGHT (GREEN)/HBC WARNING LIGHT (AMBER)
id091800005200
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)
-
• The HBC warning light (amber) warns the driver that a malfunction is occurring in the high beam control (HBC) system.
Function
HBC indicator light (green)
-
• The instrument cluster illuminates the HBC indicator light (green) based on the system conditions display request signal sent via a CAN signal from the forward sensing camera (FSC).
HBC warning light (amber)
-
• The instrument cluster illuminates the HBC warning light (amber) based on the system conditions display request signal sent via a CAN signal from the forward sensing camera (FSC).
• The instrument cluster flashes the HBC warning light (amber) based on the system malfunction display request signal sent via a CAN signal from the forward sensing camera (FSC).
• The flash pattern of the HBC warning light (amber) is as shown in the figure.
Construction
• The HBC indicator light (green) and HBC warning light (amber) are equipped in the instrument cluster.
• For vehicles with center display, a warning message in the center display is displayed when the HBC warning light (amber) is flashed. For the message content and verification method, refer to the CENTER DISPLAY. (See
CENTER DISPLAY [WITH CENTER DISPLAY].)
• For instrument cluster type B, a warning message in the multi-information display is displayed simultaneously when the HBC warning light (amber) flashes. For the message content, refer to the MULTI-INFORMATION DISPLAY. (See
MULTI-INFORMATION DISPLAY.)
Operation
HBC indicator light (green)
1. The instrument cluster receives the system conditions display request signal from the forward sensing camera (FSC) via the CAN signal.
2. The instrument cluster turns the transistor on based on the system conditions 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) illuminates.
HBC warning light (amber)
1. The instrument cluster receives the system conditions display request signal or a system malfunction display request signal from the forward sensing camera (FSC) via a CAN signal.
2. The instrument cluster turns the transistor on intermittently for a system malfunction display request signal, and continuously for a system conditions display request signal.
3. When the transistor is turned on intermittently, the HBC warning light (amber) flashes, and when it is turned on continuously, the HBC warning light (amber) illuminates.
Fail-safe
• Function not equipped.
