COMPONENT DESCRIPTION
Air Mix Door Motor
The air mix door motor is attached to the A/C unit assembly. It
rotates so that the air mix door is opened or closed to a position set
by the front air control. Motor rotation is conveyed through a shaft
and the air mix door position is then feedback to the front air control
by PBR built-in air mix door motor.

INTERIOR ROOM LAMP CONTROL SYSTEM
System DiagramINFOID:0000000001728854
System DescriptionINFOID:0000000001728855
OUTLINE
• Interior room lamps* are controlled by the interior room lamp timer control function of the BCM.
*Map lamp, interior room lamp, vanity lamps and trunk room lamp.
The timer control functions of the BCM activate based on inputs from the remote keyless entry receiver, the
key cylinder lock/unlock switch, the door switches, the key switch and key lock solenoid (without Intelligent
Key) or the key switch and ignition knob switch (with Intelligent Key).
ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM
begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.
 When the front door LH is unlocked [with Intelligent Key, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)].
 When a door opens → closes and the Intelligent Key is not inserted in the key slot.
Timer control is canceled under the following conditions.
 When the front door LH is locked [with Intelligent Key, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)].
 A door is opened (door switch turns ON).
 Intelligent Key is inserted into the key slot.
Interior lamp operational settings can be changed with the function setting of CONSULT-III.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the battery 30 minutes after the ignition switch is turned OFF.
The BCM controls power and ground to all interior lamps.
After the battery saver system turns the lamps OFF, the lamps will illuminate again when
