PRECAUTIONS
Revision: 2006 January2006 M35/M45
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NIS001WA
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.
WAR NING :
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.
Precautions for Procedures without Cowl Top CoverNIS001WB
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions Necessary for Steering Wheel Rotation after Battery DisconnectNIS001WC
NOTE:
Before removing and installing any control units, first turn the push-button ignition switch to the LOCK
position, then disconnect both battery cables.
After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, 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. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.

INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30

FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15
25 mm (0.590.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW (TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit. Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingNIS001WH
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

CAN Communication System DescriptionNIS001WR
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.

Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-83, "
WORK SUPPORT" .
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is performed using the CONSULT-II.
CAUTION:
After a new Intelligent Key-ID is registered, be sure to check the function.
When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-II can be used to check and delete Intelligent Key-IDs.
For future information, see Technical Bulletin.
STEERING LOCK UNIT REGISTRATION
Steering Lock Unit ID Registration
CAUTION:
The method for registering a steering lock unit ID depends on the status of the steering lock unit
and Intelligent Key unit (new or old unit).
After registration is completed, press ignition switch with an Intelligent Key in the vehicle so that it
can be turned, and confirm that it cannot be turned even when ignition switch is pressed without
an Intelligent Key in the vehicle.
For future information, see Technical Bulletin.

*1: When the A/T selector lever position is N position, the engine start condition is different according to the vehicle speed.
At vehicle speed of 5 km/h or less, the engine can start only when the brake pedal is depressed.
At vehicle speed of 5 km/h or more, the engine can start even if the brake pedal is not depressed. (It is the same as “Engine stall
return operation while driving”.)
*2: When the A/T selector lever position is in any position other than P position and when the vehicle speed is 5 km/h or more, the
engine stop condition is different.
Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short
a time, the operation may be invalid, so properly press and hold to prevent the incorrect operation.)
Press the push-button ignition switch 3 times or more within 1.5 seconds. (Emergency stop operation)
