to BCM terminal 38.
When ignition switch is in ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminals 49 and 52
through grounds M35, M45 and M85,
to IPDM E/R terminals 38 and 60
through grounds E21, E50 and E51.
FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the front fog lamp switch must be ON for front fog lamp operation.
With the front fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power
through IPDM E/R terminal 36
to front fog lamp RH terminal 1,
through IPDM E/R terminal 37
to front fog lamp LH terminal 1.
Ground is supplied
to front fog lamp RH and LH terminals 2
through grounds E21, E50 and E51.
With power and grounds supplied, front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS002WY
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

INTERIOR ROOM LAMP
Revision: 2006 December 2006 FX35/FX45
When the 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 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 switch (key switch OFF), 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 or power window main switch (door lock and unlock switch),
door key cylinder switch].
Driver door is opened (driver door switch turns ON).
Ignition switch ON.
With Intelligent Key System
When the interior room lamp and map lamp switch is in DOOR position, and when all conditions below are
met, BCM performs timer control (maximum 30 second) for interior room lamp and 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 15A fuse [No. 22, located in fuse and fuse block (J/B)]
through key switch and ignition knob switch terminal 3.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
And not turned ignition knob switch, power will not be supplied to Intelligent Key unit.
Ground is supplied
from BCM terminal 22
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 switch 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 Intelligent 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 switch (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 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.
