PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00I9C
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.
WA RN ING:

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.

UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter.

Warning and indicator lamps are controlled by signals drawn from the CAN communication system, BCM
(body control module), and components connected directly to the combination meter.

Odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) segments can be checked in self-
diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No. 13, located in the fuse block (J/B)]

to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 28.
Ground is supplied

to combination meter terminals 21, 22 and 23
1. Combination meter M24 2. ECM E16 3. ABS actuator and electric unit (con-
trol unit) E33

through grounds M57 and M61.
SPEEDOMETER
With ABS
The ABS actuator and electric unit (control unit) provides a vehicle speed signal to the combination meter via
CAN communication lines.
Without ABS or CVT
The vehicle speed sensor provides a vehicle speed signal to the combination meter for speedometer indica-
tion.
With CVT, Without ABS
The TCM provides a vehicle speed signal to the combination meter via CAN communication lines.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm). The 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

to combination meter terminal 24

through fuel level sensor unit and fuel pump terminal 5

through fuel level sensor unit and fuel pump terminal 2

from combination meter terminal 6.
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.
CAN COMMUNICATION SYSTEM DESCRIPTION
Refer to LAN-4, "SYSTEM DESCRIPTION" .
