PRECAUTIONS
Revision: 2006 November2007 350Z
PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS00001
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.
Precautions for Battery ServiceNKS00002
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

PRELIMINARY INSPECTION
1. CHECK BATTERY TERMINALS CONNECTION
Check if battery terminals are clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair battery terminals connection.
2. CHECK FUSE AND FUSIBLE LINK
Check for blown alternator and combination meter fuses and fusible links.
OK or NG
OK >> GO TO 3.
NG >> Be sure eliminate cause of malfunction before installing new fuse and fusible link.
3. CHECK ALTERNATOR DRIVE BELT TENSION
Check alternator drive belt tension. Refer to EM-12, "
Checking Drive Belts" .
OK or NG
OK >> INSPECTION END
NG >> Repair as needed.
DIAGNOSTIC PROCEDURE 1
Check “L” Terminal Circuit (Open)
1. CHECK “L” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “L” terminal is clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair “L” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2. CHECK “L” TERMINAL CIRCUIT (OPEN)
1. Disconnect alternator connector.
2. Apply ground to alternator harness connector terminal.
3. Check condition the charge warning lamp with the ignition
switch in the ON position.
OK or NG
OK >> Go to SC-22, "Trouble Diagnoses with Starting/Charging
System Tester (Charging)" .

Removal and Installation NKS0000H
REMOVAL
1. Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal.
CAUTION:
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent
any interference between the window edge and the vehicle when the door is opened/closed. Dur-
ing normal operation, the window slightly raises and lowers automatically to prevent any window
to vehicle interference. The automatic window function will not work with the battery discon-
nected.
2. Remove engine undercover, using power tools.
3. Remove air cleaner assembly and harness clip. Refer to EM-15, "
AIR CLEANER AND AIR DUCT" .
4. Remove radiator cooling fan assembly. Refer to CO-21, "
COOLING FAN" .
5. Remove alternator and power steering oil pump belt. Refer to EM-12, "
Removal and Installation" .
6. Disconnect alternator connector (1).
7. Remove “B” terminal mounting nut (2).
8. Remove the harness bracket bolts (A).
