System DescriptionAKS007F7
When room lamp and personal lamp switch is in DOOR position, room lamp and personal lamp ON/OFF is
controlled by timer according to signals from switches including key switch, front door switch driver side,
unlock signal from keyfob, door lock and unlock switch, key cylinder lock and unlock switch, ignition switch.
When room lamp and personal lamp turns ON, there is a gradual brightening over 1 second. When room lamp
and personal lamp turns OFF, there is a gradual dimming over 1 second.
The room lamp and personal lamp timer is controlled by the BCM (body control module).
Room lamp and personal lamp timer control settings can be changed with CONSULT-II.
Ignition keyhole illumination turns ON at time when driver door is opened (door switch ON) or removed keyfob
from key cylinder. Illumination turns OFF when driver door is closed (door switch OFF).
Step lamp turns ON at time when driver door or passenger door is opened (door switch ON). Lamp turns OFF
when driver, passenger doors are closed (all door switches OFF).
POWER SUPPLY AND GROUND
Power is supplied at all times (without intelligent key system)
