to ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]

through 15A fuse [No. 1, located in fuse block (J/B)]

to BCM (body control module) terminal 38.
When the ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM (body control module) terminal 11.
Ground is supplied

to BCM (body control module) terminals 49 and 52

through grounds M35, M45 and M85

to IPDM E/R (intelligent power distribution module engine room) terminals 38 and 60

through grounds E21, E50 and E51.
Fog Lamp Operation
The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position or
AUTO position (LOW beam is ON) and the fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the fog lamp
relay. The fog lamp relay then directs power

through IPDM E/R terminal 37

to front fog lamp LH terminal 1

through IPDM E/R terminal 36

to front fog lamp RH terminal 1.
Ground is supplied

to front fog lamp LH terminal 2

through grounds E21, E50 and E51, and

to front fog lamp RH terminal 2

through grounds E21, E50 and E51.
With power and grounds supplied, the 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 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 fog lamps (and headlamps) remain illuminated for 5 minutes, then the 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 DescriptionAKS007CJ
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 LAMPPFP:26410
Component Parts and Harness Connector LocationAKS007O8
System DescriptionAKS007F7
When room lamp and personal lamp switch is in DOOR position, room lamp and personal 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 room lamp and personal lamp turns ON, there is a gradual brightening over 1 second. When room lamp
and personal lamp turns OFF, there is a gradual dimming over 1 second.
The room lamp and personal lamp timer is controlled by the BCM (body control module).
Room lamp and personal lamp timer control settings can be changed with CONSULT-II.
Ignition keyhole illumination turns ON at time when driver door is opened (door switch ON) or removed keyfob
from key cylinder. Illumination turns OFF when driver door is closed (door switch OFF).
Step lamp turns ON at time when driver door or passenger door is opened (door switch ON). Lamp turns OFF
when driver, passenger doors are closed (all door switches OFF).
POWER SUPPLY AND GROUND
Power is supplied at all times (without intelligent key system)

through 15A fuse [No. 22, located in fuse block (J/B)]

to key switch terminal 2 and

to BCM (body control module) terminal 42

through 50A fusible link [letter M, located in fuse and fusible link block]

to BCM (body control module) terminal 55.
Power is supplied at all times (with intelligent key system)

through 10A fuse [No.38, located in fuse and fusible link block]

to key switch and ignition knob switch terminals 1

through 15A fuse [No.22, located in fuse block (J/B)]

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 interior room lamp and map lamp timer conditions are
met, and turns the interior room lamp and 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 termi-
nal 62 changes between 0V (door open) → 12V (door closed). The BCM determines that conditions for inte-
rior room lamp and map lamp operation are met and turns the 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 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 the 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 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 the interior
room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and the key is not inserted in the key switch (or not turned ignition knob
switch), BCM terminal 62 changes between 0V (door open) → 12V (door closed). The determines that condi-
tions for interior room lamp and map lamp operation are met and turns the interior room lamp ON for 30 sec-
onds.
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 terns ON).

Ignition switch ON.
