CANTS".
6. Install the boot securely into the grooves (indicated by the *
marks) as shown.
CAUTION:
If there is grease on the boot mounting surfaces (indicated
by the * marks) of the drive shaft and joint sub-assembly,
the boot may come off. Remove all grease from the drive
shaft surfaces.
7. Check that the boot installation length “L” is the specified length.
Insert a flat-tip screwdriver or similar tool into the bigger side of

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.

lTo reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
HOSE CLAMPING
lIf old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there is
a trace of tube bulging left on the old rubber hose, align rubber
hose at that position.
lDiscard old clamps; replace with new ones.
lAfter installing plate clamps, apply force to them in the direction
of the arrow, tightening rubber hose equally all around.
Precautions for Engine OilsEAS001GQ
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
lAvoid prolonged and repeated contact with oils, particularly used engine oils.
lWear protective clothing, including impervious gloves where practicable.
lDo not put oily rags in pockets.
lAvoid contaminating clothes, particularly underpants, with oil.
lHeavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
lFirst aid treatment should be obtained immediately for open cuts and wounds.
lUse barrier creams, applying them before each work period, to help the removal of oil from the skin.
lWash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
rations containing lanolin replace the natural skin oils which have been removed.
lDo not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
lIf skin disorders develop, obtain medical advice without delay.
lWhere practical, degrease components prior to handling.

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.
