OUTLINE

• Front room/map lamp and room lamp 2nd row are controlled by the interior room lamp timer control function

of the BCM.

• 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 switches, the door switches, the key switch and the power window and door lock/

unlock switches. 

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 main power window and door lock/unlock switch, or front door lock

assembly LH (key cylinder switch)].

• When a door opens 

→ closes.

Timer control is cancelled under the following conditions.

• When the front door LH is locked [with 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).

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 10 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 a 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 interior lamp battery saver control time period can be changed with the CONSULT.
