LED HEADLIGHT WARNING LIGHT


id091800014700


Purpose

•  The LED headlight warning light notifies the driver the following conditions:
―  Headlight auto leveling system non-initialization
―  Headlight auto leveling system malfunction
―  Adaptive front lighting system (AFS) malfunction (With adaptive front lighting system (AFS))
―  Adaptive LED headlights malfunction (With adaptive LED headlights)
―  LED headlight malfunction

Function

•  When the instrument cluster receives the headlight auto leveling system/adaptive front lighting system (AFS)/adaptive LED headlights malfunction or an LED headlight warning light request signal sent from the AFS control module/adaptive LED headlights control module via CAN communication, it turns the LED headlight warning light on.
•  When the instrument cluster receives the headlight auto leveling system non-initialization signal sent from the AFS control module/adaptive LED headlights control module via CAN communication, it flashes the LED headlight warning light.
•  The flash pattern of the LED headlight warning light is as shown in the figure.

Construction

•  The LED headlight warning light is built into the instrument cluster.

Operation

1.  When the AFS control module/adaptive LED headlights control module detects the headlight auto leveling system non-initialization, a headlight auto leveling system/adaptive front lighting system (AFS)/adaptive LED headlights malfunction, or an LED headlight malfunction, it sends (1) a headlight auto leveling system non-initialization, headlight auto leveling system/adaptive front lighting system (AFS)/adaptive LED headlights malfunction, or an LED headlight malfunction signal to the instrument cluster via CAN communication.
2.  The instrument cluster turns the transistor on (2) based on each signal.
3.  When the transistor turns on intermittently, the LED headlight warning light flashes (3), when it turns on continuously, the LED headlight warning light turns on (3).
