Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           EKS003KS


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:
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.
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.
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.

When you read wiring diagrams, refer to the following:
q  GI-13, "How to Read Wiring Diagrams"
q  PG-8, "POWER SUPPLY ROUTING"
When you perform trouble diagnosis, refer to the following:
q  GI-9, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"
q  GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident"
Check for any Service bulletins before servicing the vehicle.

UNIFIED CONTROL METER
q   Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
    by unified meter control unit combined with speedometer and odo/trip meter.
q   Digital meter is adopted for odo/trip meter.*
    *The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter
    is erased when the battery cable is disconnected.
q   Odo/trip meter segment can be checked in diagnosis mode.
q   Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER




                                                                                                     SEL253V

NOTE:
Turn ignition switch ON to operate odo/trip meter.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
q   through 7.5A fuse [No. 28, located in the fuse block (J/B)]
q   to combination meter terminal 31.
With the ignition switch in the ON or START position, power is supplied
q   through 10A fuse [No. 11, located in the fuse block (J/B)]
q   to combination meter terminal 32.
Ground is supplied
q   to combination meter terminal 33
q   through body grounds M14 and M68.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank. The reading on the gauge is based on the
resistance of the fuel level sensor unit.
The fuel gauge is regulated by a variable ground signal supplied
q    to combination meter terminal 47
q    through fuel level sensor unit terminal 2
q    through fuel level sensor unit terminal 4
q    through body grounds B106 and B116.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.

                                                     DI-4
                                      METERS AND GAUGES

The water temperature gauge is regulated by a variable ground signal supplied
q    to combination meter terminal 46                                                                            A
q    through thermal transmitter terminal 1.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases and the nee-
dle on the gauge moves from C to H.                                                                              B

TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).                                           C
The tachometer is regulated by a signal
q   to combination meter terminal 48
q   from ECM terminal 3.                                                                                         D
SPEEDOMETER
The vehicle speed sensor provides a voltage signal to the combination meter for the speedometer.
The voltage is supplied                                                                                          E
q   to combination meter terminals 34 and 35
q   from vehicle speed sensor terminals 1 and 2.

DIAGNOSIS FUNCTION
q    Odo/trip meter segment can be checked in diagnosis mode.
q    Meters/gauges can be checked in diagnosis mode.                                                       B
HOW TO ALTERNATE DIAGNOSIS MODE
1.   Turn ignition switch ON while pressing and holding trip reset switch for 0.8 second.
                                                                                                           C
2.   Push trip reset switch 3 times within 7 seconds.
3.   All odo/trip meter segments should be turned on.
     NOTE:
                                                                                                           D
     If some segments are not turned on, speedometer (unified
     meter control unit) with odo/trip meter should be replaced.
     At this point, the unified meter control unit is in diagnosis mode.
                                                                                                           E

4.   Push odo/trip meter switch. Indication of each meter/gauge
     should be as shown in figure at left while pushing odo/trip meter
     switch if it is not malfunctioning.
                                                                                                           H
     NOTE:
     It takes about 1 minute for indication of fuel gauge to
     become stable.
