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))
―  LED headlight malfunction

Function

•  The instrument cluster flashes the LED headlight warning light based on the following signals:

Signal name

Sending module/part name

Communication method
Headlight auto leveling system non-initialization signal
Auto leveling control module/AFS control module
HS-CAN
•  Headlight auto leveling system malfunction signal
•  Adaptive front lighting system (AFS) malfunction signal (with adaptive front lighting system (AFS))
•  LED headlight malfunction signal

•  The flash pattern of the LED headlight warning light is as shown in the figure.

Operation

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