by the auto light function.
NOTE:
ON/OFF timing differs based on the sensitivity from the setting. The setting can be set by CONSULT-III. Refer
to EXL-215, "
HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)".
DELAY TIMER FUNCTION
BCM turns the exterior lamp OFF depending on the vehicle condition with the auto light function when the igni-
tion switch is turned OFF.
