INTERIOR ROOM LAMP CONTROL SYSTEM
System DiagramINFOID:0000000005146715
System DescriptionINFOID:0000000005146716
OUTLINE
• Interior room lamps* are controlled by the interior room lamp timer control function of the BCM.
*Front room/map lamps, personal lamp 2nd row, personal lamp 3rd row (when lamp switch is in DOOR posi-
tion) and puddle lamps.
• Cargo lamp is controlled by the cargo lamp control function of the BCM.
• Step lamps* are controlled by the step lamp control function of the BCM. *Front step lamps, rear step lamps and foot lamps.
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 switc hes or the key switch and ignition knob switch.
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 ignition switch.
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
front door lock assembly LH (key cylinder switch)].
• A door is opened (door switch turns ON).
• Ignition switch is turned ON.
Interior lamp operational settings can be c hanged 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 batte ry 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 la mps 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 ignition switch.
The Interior lamp battery saver control time peri od can be changed with the function setting of CONSULT-III.
