INTERIOR ROOM LAMP
 to power window main switch (door lock and unlock switch) terminal 14.
At the time that driver door are opened, BCM detects that driver door is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns interior room lamp and map lamp ON
for 30 seconds.
Key is in ignition key cylinder (key swit ch ON), or turned ignition knob switch,
Power is supplied
 through key switch and ignition knob switch terminal 4
 to BCM terminal 37,
 through key switch and ignition knob switch terminal 2
 to intelligent key unit terminal 27.
When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
And turned ignition knob switch, power supply to Intel ligent Key unit is terminated. BCM detects that key has
been removed, determines that interior room lamp and map lamp timer conditions are met, and turns interior
room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and key is not inserted in key s witch (or not turned ignition knob switch),
BCM terminal 62 changes between 0V (door open) → 12V (door closed). BCM determines that conditions for
interior room lamp and map lamp operation are met and turns interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
 Driver door is locked [when locked keyfob, power window main switch (door lock and unlock switch) or door
key cylinder switch].
 Driver door is opened (driver door switch terns ON).
 Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If lamps is left “ON”, it will not be turned out even when door is closed.
BCM turns off lamps automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls lamps listed below:
 Ignition key hole illumination
 Front step lamp (driver side)
 Front step lamp (passenger side)
 Rear step lamp RH
 Rear step lamp LH
 Front door inside handle illumination (driver side)
 Front door inside handle illumination (passenger side)
 Rear door inside handle illumination RH
 Rear door inside handle illumination LH
 Personal lamp RH
 Personal lamp LH
 Interior room lamp (without DVD player)
 Map lamp
 Vanity mirror lamp
 Luggage room lamp
After lamps turn OFF by battery sa ver system, lamps illuminate again when
 signal from keyfob, or power window main switch (door lock and unlock switch) or key cylinder is locked or
unlocked,
 door is opened or closed,
 key is removed from ignition key cylinder or inserted in ignition key cylinder, or turned ignition knob switch.
Interior lamp battery saver control period can be changed by the function setting of CONSULT-III.
