Precautions For Liquid GasketEBS01E5N
REMOVAL OF LIQUID GASKET
lAfter removing the mounting bolts and nuts, separate the mating
surface using the seal cutter [SST] and remove the old liquid
gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
lTap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.
lIn areas where seal cutter [SST] is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
lRemove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach the liquid gasket tube to the tube presser [SST].
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
lIf there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
lAs for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.
lWithin five minutes of liquid gasket application, install the mat-
ing component.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten mounting bolts or nuts after the installation.
lAfter 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.

PRECAUTIONSPFP:00001
DescriptionEAS001GG
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EAS001GH
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:
lTo 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.
lImproper 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.
lDo 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.
Precautions for NATS (NISSAN ANTI-THEFT SYSTEM)EAS001GI
NATS will immobilize the engine if someone tries to start it without the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
lWhen NATS detects trouble, the security indicator lamp lights up while ignition switch is in "ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.
lWhen servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), CONSULT-II hardware and CONSULT-II NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
Therefore, CONSULT-II NATS software (program card and operation manual) must be kept strictly con-
fidential to maintain the integrity of the anti-theft function.
lWhen servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to
receive all keys from vehicle owner. A maximum of four or five key IDs can be registered into NATS.
lWhen failing to start the engine first time using the key of NATS, start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectEAS001HY
NOTE:
lThis Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
lRemove and install all control units after disconnecting both battery cables with the ignition knob in the
²LOCK²position.
lAlways use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.

Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
Vehicle Vibration
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gentlyapply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
lConnectors not fully seated.
lWiring harness not long enough and is being stressed due to engine vibrations or rocking.
lWires laying across brackets or moving components.
lLoose, dirty or corroded ground wires.
lWires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.
BEHIND THE INSTRUMENT PANEL
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.

Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasti-
cally affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
lRemove the ground bolt or screw.
lInspect all mating surfaces for tarnish, dirt, rust, etc.
lClean as required to assure good contact.
lReinstall bolt or screw securely.
lInspect for “add-on” accessories which may be interfering with the ground circuit.
lIf several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.
For detailed ground distribution information, refer to “Ground Distribution” in PG section.
Voltage Drop Tests
Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage
drop in a circuit is caused by a resistance when the circuit is in operation.
Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will
give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire
is not able to carry the current. The single strand will have a high resistance to the current. This will be picked
up as a slight voltage drop.
Unwanted resistance can be caused by many situations as follows:
lUndersized wiring (single strand example)
lCorrosion on switch contacts
lLoose wire connections or splices.
