System Description EKS006MB
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 and key lock solenoid, front door
switch LH side, unlock signal from keyfob, door lock and unlock switch, key cylinder lock and unlock switch,
ignition switch, and glass hatch ajar 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.
Step and foot lamp turns ON when front or rear doors are opened (door switch ON). Lamp turns OFF when
front and rear doors are closed (all door switches OFF).

● to door mirror LH and RH terminal 13 (with puddle lamps)
● to front room/map lamp assembly terminal 1 and
● to personal lamps terminal 1
● through front room/map lamp assembly terminal 2
● through BCM terminal 63, and
● to cargo lamp terminal 1 (when cargo lamp switch is in DOOR position)

● to front and rear step lamps LH and RH and foot lamp LH and RH terminal –
● through BCM terminal 62.
And power is supplied
● through BCM terminal 56
● to front and rear step lamps LH and RH terminal +

When vanity lamp (LH and RH) is ON, ground is supplied
● to vanity lamp (LH and RH) terminal 2
● through grounds M57, M61 and M79.
When cargo lamp is ON, ground is supplied through cargo lamp case ground.
ROOM LAMP TIMER OPERATION
When lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer control
(maximum 30 seconds) for interior room lamp and map lamp ON/OFF.
Power is supplied
● through 10A fuse [No. 19, located in the fuse block (J/B)]
● to key switch and key lock solenoid terminal 3.

Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
Serial data is supplied
● to BCM terminal 22
● through main power window and door lock/unlock switch terminal 14.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns the interior room lamps ON for 30 seconds.
Key is in ignition key cylinder (key switch ON), power is supplied
● through key switch and key lock solenoid terminal 4
● to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), power supply to BCM terminal
37 is terminated. BCM detects that key has been removed, determines that interior room lamp and map lamp
timer conditions are met, and turns the interior room lamps ON for 30 seconds.
When front door LH opens →closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), BCM terminal 47 changes between 0V (door open) →12V (door closed). The BCM determines
that conditions for interior room lamp operation are met and turns the interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
● Front door LH is locked [when locked by keyfob, main power window and door lock/unlock switch, or front
door lock assembly LH (key cylinder switch)]
● Front door LH is opened (front door switch LH turns ON)
● Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left “ON”, it will not be turned off even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls interior lamps listed below:
● Vanity lamp
● Room/map lamp
● Cargo lamp
● Personal lamp
● Step lamps
● Puddle lamps
● Foot lamps
After lamps turn OFF by the battery saver system, the lamps illuminate again when
● signal received from keyfob, or main power window and door lock/unlock switch or front door lock assembly LH (key cylinder switch) is locked or unlocked
● door is opened or closed
● key is removed from ignition key cylinder (key switch OFF) or inserted in ignition key cylinder (key switch
ON).
Interior lamp battery saver control period can be changed by the function setting of CONSULT-II.
