While Driving, AWD Warning Lamp Flashes Rapidly (When Flashing in Approx.
1 Minute and Then Turning OFF)
NDS000AH
NOTE:
Rapid flashing: 2 times/second
This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before lamp flashes rapidly. Both cases are not malfunction.
When this symptom occurs, stop vehicle and allow it to idle for some times. Flashing will stop and system will
be restored.
While Driving, AWD Warning Lamp Flashes Slowly (When Continuing to Flash
until Turning Ignition Switch OFF)
NDS000AI
NOTE:
Slow flashing: 1 time/2 seconds
DIAGNOSTIC PROCEDURE
1. CHECK TIRE
Check the following.

Tire pressure

Wear condition

Longitudinal tire size (There is no difference between longitudinal tires.)
OK or NG
OK >> GO TO 2.
NG >> Drive at vehicle speed of 20 km/h (12 MPH) or more for 5 seconds or more after repairing or
replacing damaged parts. (Initialize improper size tire information.)
2. CHECK INPUT SIGNAL OF TIRE DIAMETER
With CONSULT-II
1. Start engine.
2. Drive at 20 km/h (12 MPH) or more for approx. 200 seconds.
3. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
4. Check monitor “DIS-TIRE MONI”.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NES000LR
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.
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" .

Service Notice or PrecautionsNES000LT

Low tire pressure warning lamp flashes 1min, then turns ON when occurring any malfunction except low
tire pressure. Delete the memory with CONSULT-II, or register the ID to turn low tire pressure warning
lamp OFF. Refer to WT-18, "
ID Registration Procedure" .

ID registration is required when replacing or rotating wheels, replacing transmitter or BCM. Refer to WT-
18, "ID Registration Procedure" .

Replace grommet seal, valve core and cap of the transmitter in TPMS every tire replacement by reaching
wear limit of tire.
