PRECAUTIONS
PRECAUTIONS PFP:00011
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" AKS004FO
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 C
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: D
q 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. E
q 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. F
q 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.
G
Wiring Diagrams and Trouble Diagnosis AKS004FQ
When you read wiring diagrams, refer to the following:
H
q Refer to GI-14, "How to Read Wiring Diagrams" in GI section
q Refer to PG-2, "POWER SUPPLY ROUTING" for power distribution circuit in PG section
When you perform trouble diagnosis, refer to the following: I
q Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section
q Refer to GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section

System Description AKS002NH
AUDIO SYSTEM
Refer to Owner's Manual for audio system operating instructions. B
Power is supplied at all times
q through 15A fuse [No. 52, located in the fuse, fusible link and relay block (J/B)]
q to audio unit terminal 73 C
q to CD auto changer terminal 12
q through 20A fuse (No. 75, located in the fuse, fusible link and relay box)
q to BOSE speaker amp. terminal 11. D
With the ignition switch in the ACC or ON position, power is supplied
q through 10A fuse [No. 21, located in the fuse block (J/B) No.1]
q to audio unit terminal 72 and BOSE speaker amp. terminal 34. E
q to CD auto changer terminal 16.
Ground is supplied through the case of the audio unit.
Ground is also supplied to CD auto changer terminal 15 through body grounds M24 and M114. F
Ground is also supplied to BOSE speaker amp. terminal 27 through body grounds B217 and B256.
Audio unit is connected to BOSE speaker amp. as communication line.
When the audio unit is turned to the ON position, audio sound signals are supplied. G
q through audio unit terminals 12,11
q to BOSE speaker amp. terminals 5, 6.
When the audio unit is turned to the ON position, audio signals are supplied. H
q through terminals 79, 80, 81 and 82 of audio unit
q to terminals 39, 40, 38 and 41 of the BOSE speaker amp.
I
q through terminals 18, 19, 21, 20, 28, 12, 23, 22, 16, 17, 25, 24, 30 and 14 of the BOSE speaker amp.
q to instrument panel speakers and the front and rear door speakers and woofer terminals 1 and 2.
When steering switch pushed ON, signal is sent J
q from steering switch terminal 2
q through combination switch (spiral cable) terminals 15 and 7
q to multi-function switch terminal 7, then AV
q to audio unit.
AV COMMUNICATION LINE
L
Audio system components (Audio unit, BOSE speaker amplifier, etc.) are connected by AV communication line
and controlled by signals from the multi-function switch.
AUDIOPILOTTM SYSTEM M
AudioPilotTMis the sound improving system that picks up any noises or the sound of music coming into the
vehicle by a microphone equipped with audio unit, and that the BOSE speaker amp. revises the frequency
feature of music at real time in response to the frequency feature of the noise while driving and listening to
music.
q If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.
q If high frequency area noise from vehicle is loud, it adjusts high frequency element of music to be bigger
than vehicle noise.
q If vehicle noise is smaller than the setting volume, correction is not performed.
This compensate vehicle noise when listening to music.
