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 harness connec-
tors.

System DescriptionEKS002Z7
UNIFIED CONTROL METER
●Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in 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 segment can be checked in diagnosis mode.
●Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
NOTE:
Turn ignition switch to the “ON” position to operate odo/trip meter.
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 45.
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 terminal 46.
Ground is supplied
●through body grounds M27 and M70
●to combination meter terminal 47.
WATER TEMPERATURE GAUGE
Gasoline engine models
The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is received
engine coolant temperature signal from ECM. ECM is detected by water temperature sensor.
The water temperature gauge is received by a signal
●from ECM terminal 32
●to combination meter terminal 55.
The needle on the gauge moves from “C” to “H”

Diesel engine models
The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases. A variable
ground is supplied to terminal 55 of the combination meter for the water temperature gauge. The needle on
the gauge moves from “C” to “H”.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
The tachometer is regulated by a signal
●from terminal 36 (Gasoline engine models) or D1 (Diesel engine models) of the ECM
●to combination meter terminal 54 for the tachometer.
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 body grounds, B8 and B18
●through terminals 4 and 1 of the fuel level sensor unit and
●through terminals 1 and 3 of the Sub fuel level sensor unit
●to combination meter terminal 51 for the fuel gauge.
SPEEDOMETER
The combination meter provides a voltage signal to the vehicle speed signal from 4WD/ABS control unit (with-
out ESP) or 4WD control unit (with ESP).
The voltage is supplied
●from combination meter terminal 52 for the speedometer
●to terminal 20 of 4WD control unit (with ESP) or 4WD/ABS control unit (without ESP).
The speedometer converts the voltage into the vehicle speed displayed.

Meter/Gauge Operation and Odo/Trip Meter Segment Check in Diagnosis Mode
EKS002ZC
DIAGNOSIS FUNCTION
●Odo/trip meter segment can be checked in diagnosis mode.
●Meters/gauges can be checked in diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch to ON and change odo/trip meter to “TRIP A” or “TRIP B”.
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter switch.
4. Confirm that trip meter indicates “000.0”.
5. Push odo/trip meter switch more than three times within 5 seconds.
6. All odo/trip meter segments should be turned on.
NOTE:
If some segments are not turned on, unified meter control unit
with odo/trip meter should be replaced.
At this point, the unified control meter is turned to diagnosis
mode.
7. Push odo/trip meter switch. Indication of each meter/gauge
should be as shown left during pushing odo/trip meter switch if it
is no malfunctioning.
NOTE:
It takes about a few seconds for indication of fuel gauge and
water temperature gauge to become stable.
