INTERIOR ROOM LAMP

System Description
When map lamp switch is in DOOR position, map lamp ON/OFF is controlled by timer according to signals from switches including key switch, front door switch driver side, unlock signal from keyfob, door lock and unlock switch, key cylinder lock and unlock switch, ignition switch.

When map lamp turns ON, there is a gradual brightening over 1 second. When map lamp turns OFF, there is a gradual dimming over 1 second.

The map lamp timer is controlled by the BCM (body control module).

ROOM LAMP TIMER OPERATION
When map lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer control (maximum 30 seconds) for map lamp ON/OFF.

In addition, when spot turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied
- to 10 A fuse [No. 21, located in the fuse block (J/B)]
- through key switch terminal 2.

Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.

Ground is supplied
- from BCM terminal 22
- to power window main switch (door lock and unlock switch) terminal 9(*1) or
- to power window main switch (door lock and unlock switch) terminal 8(*2).

At the time that driver door is opened, BCM detects that driver door is unlocked. It determines that map lamp timer operation condition is met, and turns the map lamp ON for 30 seconds.

Key is in ignition key cylinder (key switch ON),

Power is supplied
- through key switch terminal 1
- to BCM terminal 37.

When key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated. BCM detects that key has been removed, determines that map lamp timer conditions are met, and turns the map lamp ON for 30 seconds.

When driver door opens -> closes, and the key is not inserted in the key switch (key switch OFF), BCM terminal 62 changes between 0 V (door open) -> 12 V (door closed). The BCM determines that conditions for map lamp operation is met, and turns the map lamp ON for 30 seconds.

Timer control is canceled under the following conditions.
- Driver door is locked [when locked power window main switch (door lock and unlock switch) or door key cylinder switch]
- Driver door is opened (driver door switch turns ON)
- Ignition switch ON.

NOTE:
*1: With anti pinch system for all door window
*2: Except anti pinch system for all door window

INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left "ON", it will not be turned out 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:
- Trunk room lamp
- Vanity mirror lamp
- Map lamp
- Personal lamp

After lamps turn OFF by the battery saver system, the lamps illuminate again when
- signal from power window main switch (door lock and unlock switch) or key cylinder is locked or unlocked,
