PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS00CS7
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.

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 ignition switch is in the START position, the combi-
nation meter dial lighting and illumination control switch lighting are
turned off.

HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER

The vehicle speed signal and the memory signals from the meter memory circuit are processed by the
combination meter and the mileage is displayed.

Switch modes with following procedure.

When trip transfer switch is pressed, trip meter display changes.

If trip reset switch is pressed for 1 second or more while trip A is
displayed, only trip A is reset. (Trip B operates the same way.)

If the battery is disconnected, odometer mileage will be retained
but the trip meter is reset to 0.0.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No. 19, located in the fuse block (J/B)]

to combination meter terminal 8, and

to unified meter and A/C amp. terminal 21.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 7,

through 10A fuse [No. 12, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 22.
With the ignition switch in the ACC or ON position, power is supplied

through 15A fuse [No. 10, located in the fuse block (J/B)], and

through 15A fuse [No. 11, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 46.
Ground is supplied

to combination meter terminals 5, 6 and 15

through grounds M35, M45 and M85,

to unified meter and A/C amp. terminals 29 and 30

through grounds M35, M45 and M85.

SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp.
with CAN communication line. After unified meter and A/C amp. received the vehicle speed signal, it changes
the signal to 8 pulse signal and provides the 8 pulse signal to the combination meter for the speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to unified meter and A/C amp. with CAN communication line. Unified
meter and A/C amp. provides an engine speed signal to combination meter for tachometer with communica-
tion line between unified meter and A/C amp. and combination meter.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to unified meter and A/C amp. with CAN communication
line. Unified meter and A/C amp. provides a engine coolant temperature signal to combination meter for water
temperature gauge with communication line between unified meter and A/C amp. and combination meter.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied

from unified meter and A/C amp. terminal 36

through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and

through the fuel level sensor unit (sub) terminals 2 and 1

to unified meter and A/C amp. terminal 28 for the fuel gauge.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
