1.PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to CHG-23, "Diagnosis Procedure"
.
>> GO TO 2.
2.STOP POWER GENERATION VOLT AGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variabl e control in either of the following procedures:
• After selecting “ENGINE” using CONSULT, set the DUTY value of “ALTERNATOR DUTY” to 0 % by select- ing “ALTERNATOR DUTY” with “Active Test”. Continue “Active Test” until the end of inspection. (When the
DUTY value is 0 or 100 %, the normal power generation is performed according to the characteristic of the
IC regulator of the generator.)
• Turn the ignition switch OFF, and disconnect the batte ry current sensor connector. [However, DTC (P1550 -
P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self-diagnostic results history of the engine using CONSULT.]

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951689
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for Liquid GasketINFOID:0000000009460384
REMOVAL OF LIQUID GASKET
• After removing the bolts and nuts, separate the mating surface and
remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemical Products and Sealants"

PERIODIC MAINTENANCE
ENGINE COOLANT
System InspectionINFOID:0000000009460390
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for the following:
• Improper attachment
• Leaks
•Cracks
• Damage
• Loose connections
• Chafing
• Deterioration
CHECKING RESERVOIR LEVEL
• Check if the reservoir tank coolant level is within MIN to MAX when
the engine is cool.
• Adjust coolant level if it is too much or too little.
CHECKING COOLING SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system using
suitable tool (A) and Tool (B).
WARNING:
Do not remove the radiator cap wh en the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
CHECKING RADIATOR CAP
1. Inspect the radiator cap. • Replace the cap if the metal plunger cannot be seen around the edge of the black rubber gasket.
• Replace the cap if deposits of waxy residue or other foreign material are on the black rubber gasket or
the metal retainer.
NOTE:
Thoroughly wipe out the radiator filler neck to remove any waxy residue or foreign material.
