INTERIOR ROOM LAMP
Revision: June 20062007 Versa
When key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal
37.
When the ignition knob switch is released, power will not be supplied to Intelligent Key unit terminal 27.
When front door key cylinder switch LH is unlocked, ground is supplied

to BCM terminal 7

through front door key cylinder switch LH terminal 3

through front door key cylinder switch LH terminal 2

through grounds M57 and M61.
At the time the front door LH is opened, the BCM detects the front door LH is unlocked. It determines that the
interior room lamp timer operation conditions are met, and interior room lamp ON for 30 seconds.
When the key is in ignition key cylinder (key switch ON), or ignition knob switch is pushed, power is supplied

through key switch and ignition knob switch terminal 1

to BCM terminal 37, or

through key switch and ignition knob switch terminal 3

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.
When the ignition knob switch is released, power supply to intelligent key unit is terminated. The BCM detects
that the key has been removed, determines that interior room lamp timer conditions are met, and turns room
lamp ON for 30 seconds.
When the front door LH opens → closes, and key is not inserted in key switch (or ignition knob switch is
released), BCM terminal 47 changes between 0V (door open) → 12V (door closed). BCM determines that
conditions for room lamp operation are met, and turns room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:

Front door LH is locked (with keyfob or front door key cylinder switch LH).

Front door LH is opened (front door switch LH).

Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior room 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.
After lamps are turned OFF by the battery saver system, the lamps illuminate again when

front door key cylinder switch LH is locked or unlocked

door is opened or closed

key is removed from ignition key cylinder or inserted in ignition key cylinder, or the ignition knob switch is
pushed or released.
Interior lamp battery saver control time period can be changed by the function setting of CONSULT-II.
