PRECAUTIONS PFP:00011

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

EKS00778

A

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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.

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 per­formed 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.

● through 15A fuse (No. 24, located in the fuse and fusible link box)

● to audio unit terminal 34,

With the ignition switch in the ACC or ON position, power is supplied

● through 10A fuse [No. 12, located in the fuse block (J/B)]

● to audio unit terminal 37,

Ground is supplied through the case of the audio unit.
Ground is also supplied

● through body ground M60,

● to audio unit terminal 38.

Audio signals are supplied

● through audio unit terminals 21, 22, 23, 24, 25, 26, 27, 28

● to terminals 1 and 2 of front door speaker LH and RH

● to terminals 1 and 2 of rear door speaker LH and RH (hatchback models)

● to terminals 1 and 2 of rear speaker top and low (C+C models)

● to terminals 1 and 2 of tweeter LH and RH.

When one of steering wheel audio control switches is pushed to volume down or seek down, resistance in
steering switch circuit changes depending on which button is pushed. This will change voltage. Power is sup­plied

● from audio unit terminal 11

● through combination switch (spiral cable) terminals 33 and 15

● to steering wheel audio control switch.

Ground is supplied

● from steering wheel audio control switch

● through combination switch (spiral cable) terminals 16 and 32

● from audio unit terminal 12.

When one of steering wheel audio control switches is pushed to volume up, seek up, or mode ON, resistance
in steering switch circuit changes depending on which button is pushed. This will change voltage. Power is
supplied

● from audio unit terminal 10

● through combination switch (spiral cable) terminals 34 and 14

● to steering wheel audio control switch.

Ground is supplied

● from steering wheel audio control switch

● through combination switch (spiral cable) terminals 16 and 32

● from audio unit terminal 12.

When opening or closing the roof, audio equalizer will change automatically. (C+C models)

NOTE:

● This is noise resulting from variations in field strength, such as fading noise and multi-path noise, or exter-

nal noise from trains and other sources. It is not a malfunction.

– Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-

tains or buildings blocking the signal.

– Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off of mountains or buildings.

FOR CD ONLY

Symptom Check items Possible cause

The CD cannot be played.

The sound skips, stops suddenly,
or is distorted.

Noise Inspection

● Check that the CD is not upside down.

● Check that there is no dirt, damage, or water on the disc.

● Check that there is no dirt, damage, or water on the disc.

● Check that the trouble is not due to strong vibration.

● Audio u nit

EKS0077K

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 rotation, ignition switch turned to each position, and oper­ation 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

A continuous gr owling noise occurs. The speed of the
noise varies with changes in the engine speed.

Occurs only when engine is ON.

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.

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

A cracking or snapping sound occurs with the opera-

Noise only occurs when various

tion of various switches.

electrical components are oper­ating.

The noise occurs when various motors are operating.

● Problem with the ignition condenser.

● Problem with the alternator

● Problem with the fuel pump condenser

● Relay malfunction, radio malfunction

● Problem with the motor case ground
