Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS00IZO
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.

System Description EKS00IZQ
UNIFIED METER CONTROL UNIT
q Speedometer, odometer, tachometer, fuel gauge, oil pressure gauge, voltage gauge, A/T oil temperature B
gauge (if equipped), 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, BCM (body con-
trol module), and components 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, oil pressure gauge,
voltage meter, A/T indicator, A/T temperature gauge (if equipped), fuel and temperature gauge lighting when
the ignition switch is turned on. When the lighting switch is turned on, the illumination control switch can be F
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 information, refer
to LT-128, "System Description" . G
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times H
q through 10A fuse [No.19, located in the fuse block (J/B)]
q to combination meter terminal 8.
With the ignition switch in the ON or START position, power is supplied I
q through 10A fuse [No.14, located in the fuse block (J/B)]
q to combination meter terminal 24.
Ground is supplied J
q to combination meter terminal 17
q through body grounds M57, M61 and M79.
DI
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter via CAN communication lines. L
ENGINE OIL PRESSURE GAUGE
The engine oil pressure gauge indicates whether the engine oil pressure is low or normal.
The oil pressure gauge is controlled by the IPDM E/R (intelligent power distribution module engine room). Low M
oil pressure causes oil pressure switch terminal 1 to provide ground to IPDM E/R terminal 42. The IPDM E/R
then signals the combination meter (unified meter control unit) via CAN communication lines and a low oil
pressure indication is displayed by the oil pressure gauge.
A/T OIL TEMPERATURE GAUGE (IF EQUIPPED)
The A/T oil temperature gauge indicates the A/T fluid temperature.
TCM (transmission control module) provides an A/T fluid 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.
Revision: August 2006 DI-5 2007 Armada
COMBINATION METERS
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.
SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the combination meter via CAN
communication lines.
ODO/TRIP METER
The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combi-
nation meter and the mileage is displayed.
How to Change the Display
Refer to Owner's Manual for odo/trip meter operating instructions.

How to Proceed With Trouble Diagnosis EKS00IZY
1. Confirm the symptom or customer complaint.
2. Perform preliminary check. Refer to DI-16, "Preliminary Check" .
3. According to the symptom chart, repair or replace the cause of the symptom.
4. Does the meter operate normally? If so, go to 5. If not, go to 2.
5. Inspection End.
Preliminary Check EKS00IZZ
1. CHECK WARNING INDICATOR ILLUMINATION
1. Turn ignition switch ON.
2. Make sure warning indicators (such as malfunction indicator lamp and oil pressure low/coolant tempera-
ture high warning indicator) illuminate.
Do warning indicators illuminate?
YES >> GO TO 2.
NO >> Check ignition power supply system of combination meter. Refer to DI-17, "Power Supply and
Ground Circuit Inspection" .
2. CHECK OPERATION OF SELF-DIAGNOSIS MODE (COMBINATION METER)
Perform self-diagnosis mode of combination meter. Refer to DI-12, "Self-Diagnosis Mode of Combination
Meter" .
Does self-diagnosis mode operate normally?
YES >> GO TO 3.
NO >> Check combination meter power supply and ground circuit. Refer to DI-17, "Power Supply and
Ground Circuit Inspection" .
3. CHECK ODOMETER OPERATION
Check segment display status of odometer.
Is the display normal?
YES >> GO TO 4.
NO >> Replace the combination meter. Refer to IP-13, "COM-
BINATION METER" .
WKIA1531E
4. CHECK COMBINATION METER CIRCUIT
Check indication of each meter/gauge in self-diagnosis mode.
