upside down.
Insert the DVD-ROM correctly.
A screen other than map screen is displayed. Press the “MAP” button.
The pickup lens of the DVD unit is dirty. The pickup lens can become dirty depending
on the usage of the vehicle. Clean the pickup
lens.
The screen is too dim.
The movement is slow. The temperature in the interior of the vehicle is
low. Wait until the interior of the vehicle has warmed
up.
Some pixels in the display are
darker or brighter than others. This condition is an inherent characteristic of liq-
uid crystal displays.
This is not a malfunction.
Some menu items cannot be se-
lected. Some menu items become unavailable while
the vehicle is driven. Park the vehicle in a safe location, then operate
the navigation system.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between plan view and BIRD-
VIEW
™ . This is because the quantity of the displayed in-
formation is reduced so that the screen does not
become difficult to read. There is also a chance
that names of the roads or locations may be dis-
played several times, and the names appearing
on the screen may be different because of a pro-
cessing procedure.
This is not a malfunction.
The vehicle mark is not displayed
in the correct position. The vehicle was transported after the ignition
switch was turned off, for example, by a ferry or
car transporter.
Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle mark
may be incorrect depending on the driving envi-
ronments and the levels of positioning accuracy
of the navigation system. This is not a malfunction. Drive the vehicle for a
while to automatically correct the position and
direction of the vehicle mark.
When the vehicle is travelling on a
new road, the vehicle mark is lo-
cated on another road nearby. The system automatically places the vehicle
mark on the nearest available road, because the
new road is not stored in the map data.
Updated road information will be included in the
next version of the DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the
headlights were turned on.
Set the screen to the night screen mode using
button when turning on the headlights.
The map does not scroll even
when the vehicle is moving. The current location map screen is not dis-
played.
Press the “MAP” button.
The vehicle mark is not displayed. The current location map screen is not dis-
played. Press the “MAP” button.
The GPS indicator on the screen
remains gray. GPS signals cannot be received depending on
the vehicle location, such as in a parking ga-
rage, on a road that has numerous tall buildings,
etc.
Drive on an open, straight road for a while.
A sufficient amount of GPS satellites is not avail-
able. Please wait for the satellites to move to loca-
tions available for the navigation system.
The location of the vehicle mark is
misaligned from the actual posi-
tion. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect.
Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to au-
tomatically correct the vehicle's mark position.
If this does not correct the vehicle mark posi-
tion, inspect the AV system.
The map data has a mistake or is incomplete
(the vehicle mark position is always misaligned
in the same area). Updated road information will be included in the
next version of the DVD-ROM.

BCM reads operation status of combination swit ch using combinations shown in table below.
NOTE:
Headlamp system has a dual switch.
Sample Operation: (When Lighting Switch 1ST Position Turned ON)
 When lighting switch 1ST position is turned ON, contact in combination switch turns ON. At this time if OUT-
PUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.
 When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that lighting
switch 1ST position is ON. Then BCM sends tail lamp and clearance lamp request signal to IPDM E/R using
CAN communication.
 When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and recog-
nizes that lighting switch 1S T position is continuously ON.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.
Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status When BCM is not in sleep status, OUTPUT terminals (1-5) send out ON signal every 10 ms.
2. Sleep status

< SERVICE INFORMATION >
BCM (BODY CONTROL MODULE)
When BCM is in sleep status, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low power
mode. Mean while OUTPUT 2, 3, and 4 send out ON signal every 60 ms, and accept input from lighting
switch system.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information transmission through the two communication lines (CAN
L line, CAN H line) connecting the various control units in the system. Each control unit transmits/receives
data but selectively reads required data only. For details of signals that are transmitted/received by BCM via
CAN communication, refer to LAN-43, "
CAN System Specification Chart".
BCM STATUS CONTROL
BCM changes its status depending on the operation stat us in order to save power consumption.
1. 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 isactive, CAN communication status is active.
2. Sleep transient status  This status shuts down CAN communication when ignition switch is turned OFF.
 It transmits sleep request signal to IPDM E/R and combination meter.
 2 seconds after CAN communication of all control units stops, sleep transient status is switched to CAN
communication inactive status.
3. CAN communication inactive status  With ignition switch OFF, CAN communication is not active.
 With ignition switch OFF, control performed only by BCM is active.
 3 seconds after CAN communication of all control units stops, CAN communication inactive status is
switched to sleep status.
4. Sleep status  BCM is activated with low power mode.
 CAN communication is not active.
 When CAN communication operation is detected, it switches to CAN communication status.
 When a state of the following switches changes , it switches to CAN communication state.
- Key switch
- Hazard switch

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612892
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000001612889
NOTE:
 This Procedure is applied only to models with Intell igent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.
Precaution for WorkINFOID:0000000001327777
 After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check their
operation.
 Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

CAN Communication System DescriptionINFOID:0000000001327791
CAN (Controller Area Network) is a serial communication li ne 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.
