PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS0005P
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 ServiceNKS0005Q
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.

UNIFIED METER AND A/C AMP
Revision: 2006 November2007 350Z
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS0006X
DESCRIPTION

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter and triple meter are integrated in
the A/C auto amp.

Unified meter and A/C amp. corresponds a CONSULT-III func-
tion (self-diagnosis results, CAN diagnosis support monitor and
data monitor).
COMBINATION METER CONTROL FUNCTION

Unified meter and A/C amp. receives necessary information for combination meter from each unit.

Unified meter and A/C amp. converses with the combination meter transmits a signal through with com-
munication line (TX, RX) between unified meter and A/C amp. and combination meter.
Input/output signals between unified meter and A/C amp. and combination meter.
NOTE:
Combination meter performs fail-safe operation when unified meter and A/C amp. communication is malfunctioning. Refer to DI-7,
"FAIL-SAFE" .

WARNING CHIMEPFP:24814
System DescriptionNKS00266

The buzzer for warning chime system is installed in the combination meter.

The buzzer sounds when the combination meter receives buzzer output signal from each unit through uni-
fied meter and A/C amp.
IGNITION KEY WARNING CHIME
With the key inserted into the key switch, and the ignition switch in OFF or ACC position, when driver's door is
open, the ignition key warning chime sounds.

BCM detects key inserted into the key switch, ignition switch in OFF or ACC position, and driver side door
switch ON. And then, BCM transmits buzzer output signal (ignition key warning chime) to unified meter
and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits buzzer output signal (ignition key warning chime) to combination
meter with communication line.

When combination meter receives buzzer output signal (ignition key warning chime), it sounds the buzzer.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, drivers door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sounds.

BCM detects ignition switch in OFF or ACC position, driver side door switch ON, and lighting switch in
1ST or 2ND position. And then, BCM transmits buzzer output signal (light warning chime) to unified meter
and A/C amp. with CAN communication line.

Unified meter and A/C amp. transmits buzzer output signal (light warning chime) to combination meter
with communication line.

When combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer to LT- 8 7 , "
