PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS007X5
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.
Wiring Diagrams and Trouble DiagnosisAKS007X6
When reading wiring diagrams, refer to the following:

Refer to GI-15, "How to Read Wiring Diagrams" .
Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
When performing trouble diagnosis, refer to the following:

Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
Refer to GI-27, "
How to Perform Efficient Diagnosis for an Electrical Incident" .

Noise InspectionAKS00BMR
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.
TYPE OF NOISE AND POSSIBLE CAUSE
Occurrence condition Possible cause
Occurs only when engine is
ON.A continuous growling noise occurs. The speed
of the noise varies with changes in the engine
speed.

Ignition condenser
A whistling noise occurs while the engine speed
is high. A booming noise occurs while the engine
is running and the lighting switch is ON.

Alternator
The occurrence of the noise is linked with the operation of the fuel pump.

Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating.A cracking or snapping sound occurs with the
operation of various switches.

Relay malfunction, radio malfunction
The noise occurs when various motors are oper-
ating.

Motor case ground

Motor
The noise occurs constantly, not just under certain conditions.

Rear window defogger coil malfunction

Open circuit in printed heater

Poor ground of antenna amplifier or
antenna feeder line

Mirror type film is attached on the rear win-
dow glass

After-market TV antenna and/or electrical
accessories such as radio are attached on
the rear window glass.
A cracking or snapping sound occurs while the vehicle is being driven, especially
when it is vibrating excessively.

Ground wire of body parts.

Ground due to incorrectinstallation of
parts.

Wiring connections or ashort circuit.

Locking CD Auto-changer MechanismAKS007GD
CAUTION:

Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the
changer mechanism MUST BE LOCKED to prevent the mechanism from being damaged during
shipping.

If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism

PRECAUTION OF LCD MONITOR

In order to use LED for backlight of a display, by in car temperature, brightness may change. In low tem-
perature, the refreshing rate of the picture also becomes low because of the low response of the LCD
monitor. When passenger room becomes warm, however, the LCD recovers the normal display.

Backlight sometimes flickers or darkens according to the total consumption hours and the number of times
switched ON and OFF. In this case, display unit should be replaced. (Exchange only of backlight is impos-
sible.)
