PRECAUTION
PRECAUTION PFP:00011
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS00ACO
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 C
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: D
q 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. E
q 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. F
q 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.
G
Wiring Diagrams and Trouble Diagnosis EKS00ACP
When you read wiring diagrams, refer to the following:
H
q Refer to GI-14, "How to Read Wiring Diagrams" .
q Refer to PG-4, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit.
When you perform trouble diagnosis, refer to the following: I
q Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
q Refer to GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" .

System Description EKS00ACR
UNIFIED METER CONTROL UNIT
q Speedometer, odometer, tachometer, fuel gauge, oil pressure gauge, voltage meter, A/T temperature B
gauge, and water temperature gauge are controlled by the unified meter control unit, which is built into the
combination meter.
q Warning indicators are controlled by signals drawn from the CAN communication system, and compo-
nents connected directly to the combination meter. C
q Digital meter is adopted for odometer/trip meters*, as well as the A/T position indicator display.
*The record of the odometer is kept even if the battery cable is disconnected.
D
q Odometer/trip meters and A/T indicator segments can be checked in diagnosis mode.
q Meters/gauges can be checked in diagnosis mode.
Illumination control E
The unified meter control unit outputs the speedometer, odometer/trip meters, tachometer, engine oil pressure
gauge, voltage meter, A/T indicator, A/T oil temperature gauge, fuel and temperature gauge lighting when the
ignition switch is turned on. When the headlamp (combination) switch is turned on, the illumination control F
switch can be used to adjust the brightness of the combination meter illumination and the odometer/trip meters
and meter illumination. When the ignition switch is turned from the OFF to the ON position, the combination
meter dial lighting will remain off for 0.7 seconds. For additional combination meter illumination control infor-
mation, refer to LT-151, "System Description" . G

q through oil pressure sensor terminal 2
q to combination meter terminal 20.
NOTE:
This gauge is not designed to indicate low oil level. Use the oil level gauge to check the oil level.
A/T OIL TEMPERATURE GAUGE
The A/T oil temperature gauge indicates the A/T fluid temperature.
TCM provides a A/T oil temperature signal to combination meter via CAN communication lines.
VOLTAGE GAUGE
The voltage gauge indicates the battery/charging system voltage.
The voltage gauge is regulated by the unified meter control unit.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to combination meter via CAN communication lines.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by the unified meter control unit and a variable resistor signal supplied
q to combination meter terminal 15.
q through fuel level sensor unit and fuel pump terminal 2
q through fuel level sensor unit and fuel pump terminal 5
q from combination meter terminal 16.
