Road config-
uration

Y–intersections

At a Y intersection or similar gradual divi-
sion of roads, error the direction of travel
deduced by the sensor may result in the
current-location mark appearing on the
wrong road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction.

Spiral roads

When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.

Straight roads

When driving on a long, straight road and
slow curve without stopping, map-match-
ing does not work effectively enough and
distance errors may accumulate. As a
result, the vehicle mark may deviate from
the correct location when the vehicle
turned at a corner.

Zigzag roads

When driving on a zigzag road, the map
may be matched to other roads in the simi-
lar direction nearby at every turn, and the
vehicle mark may deviate from the correct
location.

Roads laid out in a grid pattern

When driving at where roads are laid out in
a grid pattern, where many roads are run-
ning in the similar direction nearby, the
map may be matched to them by mistake
and the vehicle mark may deviate from the
correct location.

Parallel roads

When two roads are running in parallel
(such as highway and sideway), the map
may be matched to the other road by mis-
take and the vehicle mark may deviate
from the correct location.

Place

In a parking lot

When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.

If after travelling about 10km
(6miles) the correct location
has not been restored, perform
location correction and, if nec-
essary, direction correction.

Turn table

When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be
easily returned to after rotating the vehicle
on a turn table with the ignition OFF.

Slippery roads

On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.

Slopes

When parking in sloped garages, when
travelling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.

Map data

Road not displayed on the map screen

When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.

Different road pattern
(Changed due to repair)

If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.

Vehicle

Use of tire chains

When tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road.

Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.)

CURRENT LOCATION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG

In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and direc-
tion correction.

●

When location correction has not been done

–

If the receiving conditions of the GPS satellite signal is poor, if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.

●

When the vehicle has traveled by ferry, or when the vehicle has been being towed

–

Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the precise
location can be detected with GPS, the location will be corrected.

CURRENT-LOCATION MARK JUMPS

In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.

●

When map matching has been done

–

If the current location and the current-location mark are different when map matching is done, the current-
location mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a
location which is not on a road.

●

When GPS location correction has been done

–

If the current location and the current-location mark are different when the location is corrected using GPS
measurements, the current-location mark may seem to jump. At this time, the location may be “corrected”
to a location which is not on a road.

Precautions
for driving

Just after the engine is started

If the vehicle is driven off just after the
engine is started when the gyroscope
(angular speed sensor) correction is not
completed, the vehicle can lose its direc-
tion and may have deviated from the cor-
rect location.

Wait for a short while before
driving after starting the engine.

Continuous driving without stopping

When driving long distances without stop-
ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road.

Stop and adjust the orientation.

Abusive driving

Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct
detection, and may cause the vehicle mark
to deviate from the correct road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction.

How to cor-
rect location

Position correction accuracy

If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads.

Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the cor-
rection.

Direction when location is corrected

If the accuracy of location settings during
correction is poor, accuracy may be
reduced afterwards.

Perform direction correction.

Revision; 2004 April

CURRENT LOCATION MARK IS IN A RIVER OR SEA

The navigation system moves the current-location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.

WHEN DRIVING ON SAME ROAD, SOMETIMES CURRENT-LOCATION MARK IS IN RIGHT
PLACE AND SOMETIMES IT IS WRONG PLACE

The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.

LOCATION CORRECTION BY MAP-MATCHING IS SLOW

●

The map matching function needs to refer to the data of the surrounding area. It is necessary to drive
some distance for the function to work.

●

Because map matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be cor-
rected until some special feature is found.

ALTHOUGH GPS RECEIVING DISPLAY IS GREEN, VEHICLE MARK DOES NOT RETURN TO
CORRECT LOCATION

●

The GPS accuracy has an error of approximately 10 m (30 ft). In some cases the current-location mark
may not be on the correct street, even when GPS location-correction is done.

●

The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.

●

GPS location correction may not be performed when the vehicle is stopped.

NAME OF CURRENT PLACE IS NOT DISPLAYED

The current place name may not be displayed if there are no place names displayed on the map screen.

CONTENTS OF DISPLAY DIFFER FOR BIRDVIEW™ AND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW™ screen from the flat map screen are as follows.

●

The current place name displays names which are primarily in the direction of vehicle travel.

●

The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.

●

The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.

●

Some thinning of the character data is done to prevent the display becoming to complex. In some cases
and in some locations, the display contents may differ.

●

The same place name, street name, etc. may be displayed multiple times.

PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

AKS007KU

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

WARNING:

●

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

BCM (BODY CONTROL MODULE)

BCS-3

BCS

Revision; 2004 April

BCM (BODY CONTROL MODULE)

PFP:284B2

System Description

AKS004CD

●

BCM (Body Control Module) controls the operation of various electrical units installed on the vehicle.

BCM FUNCTION

BCM has a combination switch reading function for reading the operation of combination switches (light, wiper
washer, turn signal) in addition to the function for controlling the operation of various electrical components.
Also, it functions as an interface that receives signals from the unified meter and A/C amp., and sends signals
to ECM using CAN communication.

COMBINATION SWITCH READING FUNCTION

Description

●

BCM reads combination switch (light, wiper washer, turn signal) status, and controls various electrical
components according to the results.

●

BCM reads information of 20 switches and 5 diagnostic results by combining five output terminals
(OUTPUT 1 - 5) and five input terminals (INPUT 1 - 5).

Operation description

●

BCM outputs battery voltage from input terminals (INPUT 1 - 5) all the time. At the same time output ter-
minals (OUTPUT 1 - 5) activate transistors in turn, and allow current to flow. At this time, if any (1 or
more) of the switches are ON, the input terminals corresponding to these switches detect current flow,
and the interface of BCM detects the condition. Then BCM judges switches are ON.

BCM - Operation table of combination switches

SKIA4106E

BCS-4

BCM (BODY CONTROL MODULE)

Revision; 2004 April

2003 Murano

●

BCM reads operation status of combination switches by the combination shown in the table.

NOTE:
Dual switches are set for head lamps.

Example (When fog lamp switch is turned ON)

●

When fog lamp switch is turned ON, contact in combination switch turns ON. At this time if OUTPUT 4
transistor is activated, BCM detects current flow in INPUT 5.

●

When OUTPUT 4 transistor is ON, BCM detects current flow in INPUT 5, and judges fog lamp switch is
ON. Then BCM sends fog lamp ON signal to IPDM E/R using CAN communication.

●

When OUTPUT 4 transistor is activated again, BCM detects current flow in INPUT 5, and confirms fog
lamp switch is continuously ON.

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore, after a switch is turned ON,
the electrical loads are activated with a time delay, but this time delay is so short that it cannot be noticed.

Revision; 2004 April

2003 Murano

Operation mode

●

Combination switch reading function has operation modes shown below.

Normal mode

●

When BCM is not in sleep mode, each OUTPUT (1 - 5) terminal turns ON-OFF at 10 ms intervals.

Sleep mode

●

When BCM is in sleep mode, transistors of OUTPUT 1 and 2 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (3 - 5) turn ON-OFF at 60 ms intervals, and receive lighting switch
input only.

CAN COMMUNICATION CONTROL

CAN communication is capable of dealing with a lot of information through the two communication lines (CAN
L-line, CAN H-line) connecting control units in the system. Also each control unit functions to transmit and
receive data, and reads necessary information only.

BCM STATUS CONTROL

BCM changes its status depending on the operation status in order to save power consumption.

CAN communication status

●

With ignition switch ON, CAN communicates with other control units normally.

●

Control by BCM is being operated properly.

●

When ignition switch is OFF, switching to sleep mode is possible.

●

Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.

Sleep status

●

This is the status to stop CAN communication when ignition switch is turned OFF.

●

It transmits sleep request signal to IPDM E/R and combination meter.

●

Two seconds after CAN communication with another control unit stops, it switches to CAN communica-
tion inactive status.

CAN communication inactive status

●

With ignition switch OFF, CAN communication is not active.

●

With ignition switch OFF, control performed only by BCM is active.

●

Two seconds after CAN communication with another control unit stops, it switches to CAN communica-
tion inactive status.

Sleep status

●

BCM is activated with low-current-consumption mode.

●

CAN communication is not active.

●

When CAN communication operation is detected, it switches to CAN communication status.

●

When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.

●

It changes combination switch reading function.
