INTERIOR ROOM LAMP CONTROL SYSTEM

System Diagram

INFOID:0000000005255030

System Description

INFOID:0000000005255031

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 rear map lamps) or room lamp 2nd row (without rear

map lamps).

• 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

front door lock assembly LH (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

• 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 function setting of CONSULT-III.

ILLUMINATION CONTROL SYSTEM

System Diagram

INFOID:0000000005255034

System Description

INFOID:0000000005255035

The illumination lamps operation is dependent upon the position of the lighting switch (combination switch).

When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated) the BCM

(body control module) receives input requesting the parking lamps to illuminate. This input is communicated to

the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU

(central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs

power to the parking and illumination lamps, which then illuminate.

BATTERY SAVER CONTROL

When the lighting switch (combination switch) is in the 1ST or 2ND position and the ignition switch is turned

from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the illumination

lamps remain illuminated for 30 minutes unless the lighting switch position is changed. If the lighting switch

position is changed, then the illumination lamps are turned off after a 30 second delay. When the lighting

switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after illumination lamps

have been turned off by the battery saver control, the illumination lamps illuminate again.

Description

BCM

The BCM monitors the lighting switch position with the combina-
tion switch reading function. The BCM requests, via CAN com-
munication, that the IPDM E/R activate the tail lamp relay.

IPDM E/R

The IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication network.

Combination meter (illumination control switch)

The illumination control switch is a part of the combination meter.
The combination meter controls illumination intensity by varying
ground to the illumination lamps based on the illumination control
switch position.

Combination switch

The combination switch provides input to the BCM about the light-
ing switch position.
