System Description

AKS005P3

Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The light-
ing switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.When
the lighting switch is placed in the fog lamp position the BCM (body control module) receives input signal
requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communicated
to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The
CPU (central processing unit) of the IPDM E/R (intelligent power distribution module engine room) controls the
front fog lamp relay coil. When activated, this relay directs power to the front fog lamps.

Power is supplied at all times

●

through 15A fuse [No. 88, located in IPDM E/R (intelligent power distribution module engine room)]

●

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

●

room)].

Power is also supplied at all times

●

to BCM (body control module) terminal 42.

When the ignition switch is in ON or START position, power is supplied

●

through 10A 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 M14 and M78

●

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

●

through grounds E13, E26 and E28.

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 E13, E26 and E28

●

to front fog lamp RH terminal 2

●

through grounds E13, E26 and E28.

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 Description

AKS004JX

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.

Aiming Adjustment

AKS00AMA

The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

●

Keep all tires inflated to correct pressure.

●

Place vehicle on level ground.

●

See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver seat.

Adjust aiming in the vertical direction by turning the adjusting screw.

1.

Set the distance between the screen and the center of the fog
lamp lens as shown at left.

2.

Turn front fog lamps ON. 

3.

Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is in the hatched area as shown in the
figure.

●

When performing this adjustment, cover the headlamps and
the opposite fog lamp, if necessary.

Bulb Replacement 

AKS00AMB

1.

Remove fender protector front. Refer to 

EI-22, "FENDER PRO-

TECTOR"

   in “EI” section.

2.

Remove the one side of front bumper where a fog lamp bulb to
be changed.

3.

Disconnect connector.

4.

Turn bulb socket counterclockwise and unlock it.

5.

Install in the reverse order of removal.

CAUTION:

●

Do not touch the glass of bulb directly by hand. Keep
grease and other oily matters away from it. Do not touch bulb by hand while it is lit or right after
being turned off. Burning may result.

●

Do not leave bulb out of fog lamp reflector for a long time because dust, moisture smoke, etc. May
affect the performance of fog lamp. When replacing bulb, be sure to replace it with new one.

LH Turn

When the turn signal switch (combination switch) is moved to the left position, the BCM (body control module)
receives input signal requesting the left turn signals to flash. The BCM then supplies power

Ground is supplied to the front combination lamp LH terminal 8 through grounds E13, E26 and E28.
Ground is supplied to the rear combination lamp LH terminal 4 through grounds B7 and B20.
The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 across the CAN communica-

TURN SIGNAL AND HAZARD WARNING LAMPS

Revision: 2004 November

2004 Murano

RH Turn

When the turn signal switch (combination switch) is moved to the right position, the BCM (body control mod-
ule) receives input signal requesting the right turn signals to flash. The BCM then supplies power

●

through BCM (body control module) terminal 46

●

to front combination lamp RH terminal 2

●

to rear combination lamp RH terminal 3.

Ground is supplied to the front combination lamp RH terminal 8 through  grounds E13, E26 and E28.
Ground is supplied to the rear combination lamp RH terminal 4 through  grounds B7 and B20.
The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 across the CAN communica-
tion lines. 
The unified meter and A/C amp. which received the turn indicator signal makes a right turn signal indicator
turn on in combination meter. 
With power and input supplied, the BCM controls the flashing of the RH turn signal lamps.

HAZARD LAMP OPERATION

Power is supplied at all times

●

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

●

to BCM (body control module) terminal 55

●

through 10A fuse [No. 18, located in fuse block (J/B)]

●

to BCM (body control module) terminal 42

●

through 10A fuse [No. 19, located in fuse block (J/B)]

●

to unified meter and A/C amp. terminal 21

●

through 10A fuse [No. 21, located in fuse block (J/B)]

●

to combination meter terminal 21.

Ground is supplied

●

to BCM terminals 49 and 52

●

through grounds M14 and M78

●

to unified meter and A/C amp. terminals 29 and 30

●

through grounds M14 and M78

●

to combination meter terminals 22, 23 and 24

●

through grounds M14 and M78.

When the hazard switch is depressed, ground is supplied

●

to BCM terminal 29

●

through combination meter terminal 9

●

to combination meter terminals 22, 23 and 24 

●

through grounds M14 and M78.

The BCM then supplies power 

●

through BCM terminal 45

●

to front combination lamp LH terminal 2

●

to rear combination lamp LH terminal 3

●

through BCM terminal 46

●

to front combination lamp RH terminal 2

●

to rear combination lamp RH terminal 3.

Ground is supplied

●

to the front combination lamp LH terminal 8 through grounds E13, E26 and E28

●

to the front combination lamp RH terminal 8 through grounds E13, E26 and E28

●

to the rear combination lamp LH terminal 4 through grounds B7 and B20

●

to the rear combination lamp RH terminal 4 through grounds B7 and B20.

The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 across the CAN communica-
tion lines.
