LED HEADLIGHT WARNING LIGHT

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.

  

Construction

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

  

Operation

• 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.

• The instrument cluster turns the transistor on (2) intermittently based on each signal.

• When the transistor turns on intermittently, the LED headlight warning light flashes (3).

Fail-safe

• Not applicable
