PRECAUTIONS

FOR USA AND CANADA

FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000007540705

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

FOR USA AND CANADA : Precaution for Procedure without Cowl Top Cover

INFOID:0000000007540706

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

FOR USA AND CANADA : Precaution for Work

INFOID:0000000007540707

• After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check their

operation.

• Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

Perform symptom diagnosis and narrow down the malfunctioning parts.

>> GO TO 8.

6.

CHECK COMBINATION METER POWER SUPPLY AND GROUND CIRCUITS

Inspect combination meter power supply and ground circuits. Refer to

MWI-44, "COMBINATION METER :

Diagnosis Procedure"

.

Is inspection result OK?

YES

>> GO TO 7.

NO

>> GO TO 8.

7.

REPLACE COMBINATION METER

Replace combination meter.

COMBINATION METER

• The combination meter receives the information required to control the operation of each gauge, indicator/

warning lamp, and information display via CAN communication from each unit, each switch, and sensor.

• The combination meter incorporates a trip computer that displays warnings and messages on the informa-

tion display according to the information received from various units.

• The combination meter incorporates a buzzer function that sounds an audible alarm with the integrated

buzzer device. Refer to

WCS-5, "WARNING CHIME SYSTEM : System Description"

for further details.

• The combination meter integrates the meter circuit check function and the segment check function that

checks the information display operation.

IPDM E/R

• IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch signal to

the combination meter via BCM with the CAN communication line.

• IPDM E/R is equipped with the diagnosis function. It can perform the operation check of oil pressure warning

lamp with the auto active test and the diagnosis with CONSULT.
