PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00367
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 EKS00368
When reading wiring diagrams, refer to the following:
GI-14, "How to Read Wiring Diagrams" in GI section
PG-2, "POWER SUPPLY ROUTING" for power distribution circuit in PG section
When performing trouble diagnosis, refer to the following:
GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section
GI-23, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section

System DescriptionEKS00EGZ
UNIFIED CONTROL METER
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.
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 segments can be checked in diagnosis mode.
Meter/gauge can be checked in diagnosis mode.
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.
Ambient temperature indicator indicates signal from ambient sensor processed by combination meter.
Depressing the odo/trip meter switch toggles the mode in the following order.
The odo/trip meter display mode toggling and trip display resetting 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 (The same way for trip B).
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
through 10A fuse [No. 28, located in the fuse block (J/B)]
to combination meter terminal 1.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 11, located in the fuse block (J/B)]
to combination meter terminals 2.
Ground is supplied
to combination meter terminals 21
through grounds M27 and M70.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter for water temperature gauge with
CAN communication line.

TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to combination meter for tachometer with CAN communication line.
SPEEDOMETER
ESP/TCS/ABS control unit (with ESP) or ABS actuator and electric unit (without ESP) provides a vehicle
speed signal to the combination meter for the speedometer with CAN communication line.
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 grounds B8 and B18 (LHD models)
from grounds B107 and B119 (RHD models)
through terminal 1 and 4 of the fuel level sensor unit
through terminal 3 and 1 of the sub fuel level sensor unit and
to combination meter terminal 8 for the fuel gauge.
AMBIENT TEMPERATURE INDICATOR
The ambient temperature is indicated by the signal from ambient sensor.
Combination meter inputs voltage conversed from resistance which ambient sensor detects.
Indication range is between −30 and 55 °C (−22 and 131 °F). When ambient air temperature is less than −30
°C (−22 °F) or more than 55 °C (131 °F), display shows “---°C”. When indicated temperature becomes less
than 3 °C (37 °F), ambient temperature indicator flashes as a sign of warning.
Without Auto A/C
Power is supplied
through combination meter terminal 27
to ambient sensor terminal 1.
Ground is supplied
to combination meter terminal 28
through ambient sensor terminal 2.
Signal is supplied
through ambient sensor terminal 1
to combination meter terminal 27.
With Auto A/C
Power is supplied
through auto amp terminal 9
to ambient sensor terminal 1.
Ground is supplied
to combination meter terminal 28 and auto amp terminal 24
through ambient sensor terminal 2.
And combination meter receives ambient sensor signal from ambient sensor
through ambient sensor terminal 1
to combination meter terminal 27.
NOTE:
Combination meter distinguishes whether or not the combination meter terminal 29 receives voltage (auto A/C
recognition signal) from auto amp terminal 28. If the terminal receives, combination meter discerns as auto A/
C.
Indication When Turning Ignition Switch OFF
In a case that temperature detected by ambient sensor is higher than indicated temperature before turn-
ing ignition switch OFF.
–In a case of more than 3.5 hours after turning ignition switch OFF, temperature detected by ambient sen-
sor is indicated when turning ignition switch ON.

COMBINATION METERS
–In a case of less then 3.5 hours after turning ignition switch OFF, temperature at the time of turning ignition
switch off is indicated.
In a case that temperature detected by ambient sensor is lower than indicated temperature before turning
ignition switch OFF.
–Temperature detected by ambient sensor is indicated when turning ignition switch ON.
Indication During Running
Though temperature detected by ambient sensor temporarily changed, indicating temperature continentally
indicates.
In a case that temperature detected by ambient sensor is higher than indicated temperature.
–If vehicle speed is more than 20 km/h (13 MPH), elevation of indicating temperature is limited according to
the speed until temperature detected by ambient sensor is indicated.
NOTE:
Vehicle speed 20 km/h (13 MPH): 256 sec., 25 km/h (16 MPH): 238 sec., 35 km/h (22 MPH): 200 sec., 50
km/h (31 MPH): 144 sec., 65 km/h (40 MPH): 88 sec., more than 80 km/h (50 MPH): 32 sec.
–If vehicle speed is more than 20 km/h (13 MPH), and that temperature detected by ambient sensor
becomes 8 °C (46 °F) more than indicating temperature, indicating temperature will be elevated unit the
degree becomes same as temperature detected by ambient sensor with limiting elevation of indicating
temperature 1 °C par a minute.
–If vehicle speed is less than 20 km/h (13 MPH), indicating temperature is continually kept.
In a case that temperature detected by ambient sensor is lower than indicated temperature.
–Temperature detected by ambient sensor is indicated during running.
CAN CommunicationEKS00EH0
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.
