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" .

A/C and AV Switch Self-Diagnosis FunctionAKS00BMP
It can check ON/OFF operation of each switch in the A/C and AV switch and diagnose the input signals to the
audio steering wheel switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “MUTE/II ” and
“PREV ” simultaneously for 3 seconds.
DIAGNOSIS FUNCTION
The following are checked:
All the indicators (LED) in the A/C and AV switch.
Continuity of the switches by sounding the buzzer when the A/C and AV switch is pressed.
Continuity of harness between A/C and AV switch and audio steering wheel switch.
EXITING THE SELF-DIAGNOSIS MODE
Turn ignition switch OFF.
Trouble DiagnosisAKS00BMQ
The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
MALFUNCTION WITH RADIO, TAPE AND CD (BASE SYSTEM)
Make sure that operation excepting audio system can be done with A/C and AV switch. If not, refer AV- 8 4 , "A/
C and AV Switch Does Not Operate" to repair malfunctioning parts.

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
sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the Audio unit, press the
same disc selection button again within 5 seconds.
The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and
then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.
Removal and Installation of Audio UnitAKS005TO
REMOVAL
1. Perform damper lock operation. Refer toAV- 4 4 , "Locking CD Auto-changer Mechanism" .
2. Remove cluster lid C. Refer to IP-11, "
Removal and Installation" .
3. Remove screws (6) with power tool, and remove audio unit with
display and unified meter and A/C amp. from instrument panel.
INSTALLATION
Install in the reverse order of removal.
