OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK AIR BAG FUSE AGAIN
Replace “AIR BAG” fuse and turn ignition switch ON.
Does the
“AIR BAG” fuse blow again?
YES >> Repair or replace main harness.
NO >> INSPECTION END
4. CHECK DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is “AIR BAG” displayed on CONSULT-II?
YES or NO
YES >> GO TO 5.
NO >> Visually check the wiring harness connection of diagno- sis sensor unit. If the harness connection check result is
OK, replace diagnosis sensor unit.
5. CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
OK or NG
OK >> Replace diagnosis sensor unit.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NDS0009M
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.
PrecautionsNDS0009N

Before connecting or disconnecting the AWD control unit
harness connector, turn ignition switch “OFF” and discon-
nect battery ground cable. Because battery voltage is
applied to AWD control unit even if ignition switch is turned
“OFF”.

When connecting or disconnecting pin connectors into or
from AWD control unit, take care not to damage pin termi-
nals (bend or break).
When connecting pin connectors, make sure that there are
no bends or breaks on AWD control unit pin terminal.

Before replacing AWD control unit, perform AWD control
unit input/output signal inspection and make sure whether
AWD control unit functions properly or not. Refer to TF-20,
"AWD Control Unit Input/Output Signal Reference Values" .

COMPONENTS FUNCTION DESCRIPTION
CAN CommunicationNDS0009X
SYSTEM DESCRIPTION
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.
For details, refer to LAN-32, "
CAN Communication Unit" .
Component parts Function
AWD control unit

Controls driving force distribution by signals from each sensor and switch from rear wheel driving
mode (0:100) to AWD mode (50:50).

2WD mode is available by fail-safe function if malfunction is detected in AWD system.
Wheel sensors Detects wheel speed.
AWD solenoid Controls electric controlled coupling by command current from AWD control unit.
Electric controlled coupling Transmits driving force to front final drive.
AWD warning lamp

Illuminates if malfunction is detected in electrical system of AWD system.

There is 1 blink in 2 seconds if rotation difference of front wheels and rear wheels is large.

There are 2 blinks in 1 second if load is still applied to driving parts.
ABS actuator and electric unit
(control unit) Transmits the following signals via CAN communication to AWD control unit.

Vehicle speed signal

Stop lamp switch signal (brake signal)
ECM Transmits the following signals via CAN communication to AWD control unit.

Accelerator pedal position signal

Engine speed signal
Unified meter and A/C amp. Transmits conditions of parking brake switch via CAN communication to AWD control unit.

harness connectors.
PrecautionsNES000LS

Before connecting or disconnecting the BCM harness con-
nector, turn ignition switch “OFF” and disconnect the bat-
tery cable from the negative terminal. Battery voltage is
applied to BCM even if ignition switch is turned “OFF”.

When connecting or disconnecting pin connectors into or
from BCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on BCM pin terminals.

Before replacing BCM, perform control unit input/output
signal inspection and make sure whether BCM functions
properly or not. Refer to WT-17, "
Control Unit Input/Output
Signal Standard" .
