System Diagram
INFOID:0000000007355218
System Description
INFOID:0000000007355219
OUTLINE
• Interior room lamps* are controlled by the interior room lamp timer control function of the BCM.
*Front room/map lamp, personal lamp 2nd row (with personal lamp 2nd row) or room lamp 2nd row (without
personal lamp 2nd row).
• Cargo lamp is controlled by the cargo lamp control function of the BCM.
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 (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 LH (key cylinder switch)].
• When a door opens
→
closes and the Intelligent Key is not inserted in the key slot.
Timer control is cancelled under the following conditions.
• When the front door LH is locked [with Intelligent Key, main power window and door lock/unlock switch, or

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 15 minutes (early production) or 10 minutes (late produc-
tion) 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
• a signal is received from an Intelligent Key or main power window and door lock/unlock switch, or when the
front door lock assembly LH (key cylinder switch) is locked or unlocked
• a door is opened or closed
• the Intelligent Key is removed from or inserted into the key slot.
The Interior lamp battery saver control time period can be changed with the CONSULT.
