Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ABS009A8
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 Liquid GasketABS005ZR
REMOVAL OF LIQUID GASKET SEALING

After removing mounting bolts and nuts, separate the mating
surface using a seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where seal cutter is difficult to use, use plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

COMBINATION METERS
Revision: 2004 November 2004 FX35/FX45
COMBINATION METERSPFP:24814
System DescriptionAKS005MH
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter*.
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter, A/T indicator and ICC system display segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination Control
The unified meter control unit outputs the odo/trip meter and A/T
indicator lighting when the ignition switch is turned on. When the
lighting switch is turned on, light on for the combination meter dial,
illumination control switch and external lighting are output. In addi-
tion, when the lighting switch is turned on, the illumination control
switch on the left side of the combination meter can be used to
adjust the brightness of each light. The brightness can be adjusted
to sixteen different levels: From 0 (no lights) to 15 (maximum).
Pressing the illumination control switch will brighten or darken the
lights. When the key switch is in the START position, the combina-
tion meter dial lighting and illumination control switch lighting are
turned off.
UNIFIED METER AND A/C AMP.

to Intelligent Key unit terminal 27.
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 1.
Front door switch (driver side) is case grounded.
BCM sends front door switch signal to Intelligent Key unit with CAN communication line.
Intelligent Key unit detects ignition knob return is forgotten, and sends key warning signal to unified meter and
A/C amp. with CAN communication line. Unified meter and A/C amp. sends key warning signal to combination
meter with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives key warning signal, it sounds warning chime.
LIGHT WARNING CHIME
With the key removed from the ignition switch or with the ignition knob is in LOCK (push switch OFF) [with
Intelligent Key], the driver's door open, and the lighting switch in ON position, the warning chime will sound.
[Except when headlamp battery saver control operates (for 5 minutes after ignition switch is turned to OFF or
ACC position) and headlamps do not illuminate.]
Signal is supplied

from combination switch (lighting switch) terminals 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10

to BCM terminals 2, 3, 4, 5, 6, 32, 33, 34, 35 and 36.
NOTE:
BCM detected lighting switch in 1st or 2nd position, refer to BCS-3, "
COMBINATION SWITCH READING
FUNCTION" .
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 1.
Front door switch (driver side) is case grounded.
BCM detects headlamps are illuminated, and sends light warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends light warning signal to combination meter with
communication line between unified meter and A/C amp. and combination meter.
When combination meter receives light warning signal, it sounds warning chime.
SEAT BELT WARNING CHIME
With ignition switch turned ON and seat belt unfastened [seat belt buckle switch (driver side) ON], warning
chime will sound for approximately 6 seconds.
Ground is supplied

to combination meter terminal 9

through seat belt buckle switch (driver side) terminal 60.
Seat belt buckle switch (driver side) terminal 61A is grounded through body grounds B15 and B45.
Combination meter sends seat belt unfastened [seat belt buckle switch (driver side) ON] signal to unified
meter and A/C amp. with communication line between unified meter and A/C amp. and combination meter.
BCM receives seat belt unfastened [seat belt buckle switch (driver side) ON] signal from unified meter and A/
C amp. with CAN communication line, and sends seat belt warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends seat belt warning signal to combination meter
with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives seat belt warning signal, it sounds warning chime.
CAN Communication System DescriptionAKS007Z2
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS007YY
Refer to LAN-6, "CAN Communication Unit" in “LAN SYSTEM”.
