Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

AKS004FR

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 Diagnosis

●

Refer to

GI-14, "How to Read Wiring Diagrams"

●

Refer to

PG-3, "POWER SUPPLY ROUTING CIRCUIT"

for power distribution circuit.

When you perform trouble diagnosis, refer to the following:

●

Refer to

GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"

●

Refer to

GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident"

COMBINATION METERS

PFP:24814

System Description

AKS004FU

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 and CVT indicator 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 CVT
indicator lighting when the ignition switch is turned on. When the
lighting switch is turned on, light on for the combination meter dial,
odo/trip meter and illumination control switch and external lighting
are output. In addition, when the lighting switch is turned on, the illu-
mination 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 (maxi-
mum). Pressing the illumination control switch will brighten or darken
the lights. When the key switch is in the START position, the combi-
nation meter dial lighting and illumination control switch lighting are
turned off.

UNIFIED METER AND A/C AMP.

Refer to

DI-31, "System Description"

in “UNIFIED METER AND A/C AMP”.

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.

●

Depressing the odo/trip meter switch toggles the mode in the following order.

●

The odo/trip meter display mode toggling and trip display reset-
ting can be identified by the amount of time that elapses from
pressing the odo/trip meter switch to releasing it.

●

When resetting with trip A displayed, only trip A display is reset
(Trip B operates the same way).

POWER SUPPLY AND GROUND CIRCUIT

Power is supplied at all times

●

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

●

to unified meter and A/C amp. terminal 21

●

through 10A fuse [No. 21, located in the fuse block (J/B)]

●

to combination meter 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 20

●

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 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 22, 23 and 24

●

through body grounds M14 and M78

●

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

●

through body grounds M14 and M78.

WATER TEMPERATURE GAUGE

The water temperature gauge indicates the engine coolant temperature.
ECM provides a engine coolant temperature signal to unified meter and A/C amp. with CAN communication
line. Unified meter and A/C amp. provides a water temperature signal to combination meter for water temper-
ature gauge with communication line between unified meter and A/C amp. and combination meter.

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.

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 7, and

●

through the fuel level sensor unit (sub), and

●

through the fuel level sensor unit and fuel pump (main) terminals 6 and 2

●

to unified meter and A/C amp. terminal 28 for the fuel gauge.

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

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.
