PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000006496471

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:

• 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:

• 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.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000006496472

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

On Board Diagnostic (OBD) System of Engine

INFOID:0000000006496473

The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.

CAUTION:

• Be sure to turn the ignition switch OFF and disconnect the battery negative cable before any repair

or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MI to light up.

• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will

cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

PIIB3706J

PRECAUTIONS

EC-809

< PRECAUTION >

[K9K]

• Certain systems and components, especially those related to OBD, may use a new style slide-lock-

ing type harness connector. For description and how to disconnect, refer to

PG-4, "Harness Connec-

tor"

• Be sure to route and secure the harnesses properly after work. The interference of the harness with

a bracket, etc. may cause the MI to light up due to the short circuit.

• Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube

may cause the MI to light up due to the malfunction of the fuel system, etc.

• Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM before

returning the vehicle to the customer.

General Precautions

INFOID:0000000006496474

• Always use a 12 volt battery as power source.
• Do not attempt to disconnect battery cables while engine is

running.

• Before connecting or disconnecting the ECM harness con-

nector, turn ignition switch OFF, wait 3 minutes and discon-
nect battery negative cable. Failure to do so may damage the
ECM because battery voltage is applied to ECM even if igni-
tion switch is turned OFF.

• Before removing parts, turn ignition switch OFF and then dis-

connect battery negative cable.

• Do not disassemble ECM.

• When connecting ECM harness connector, fasten (A) it

securely with levers (1) as far as they will go as shown in the
figure.

- ECM (2)
- Loosen (B)

• When connecting or disconnecting pin connectors into or

from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.

• Securely connect ECM harness connectors.

A poor connection can cause an extremely high (surge) volt-
age to develop in coil and condenser, thus resulting in dam-
age to IC's.

EC-810

< PRECAUTION >

[K9K]

PRECAUTIONS

• Keep engine control system harness at least 10cm (4 in) away from adjacent harness, to prevent

engine control system malfunctions due to receiving external noise, degraded operation of IC's, etc.

• Keep engine control system parts and harness dry.
• Handle mass air flow sensor carefully to avoid damage.
• Do not disassemble mass air flow sensor.
• Do not clean mass air flow sensor with any type of detergent.
• Even a slight leak in the air intake system can cause serious incidents.
• Do not shock or jar the camshaft position sensor, crankshaft position sensor.
• When measuring ECM signals with a circuit tester, never allow

the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.

• Do not use ECM ground terminals when measuring input/out-

put voltage. Doing so may result in damage to the ECM's tran-
sistor. Use a ground other than ECM terminals, such as the
ground.

• Do not disassemble fuel pump.

If NG, take proper action.

• Do not disassemble fuel injector.

If NG, replace fuel injector.

• Do not depress accelerator pedal when staring.
• Immediately after staring, do not rev up engine unnecessarily.
• Do not rev up engine just prior to shutdown.

• When installing C.B. ham radio or a mobile phone, be sure to

observe the following as it may adversely affect electronic
control systems depending on installation location.

- Keep the antenna as far as possible from the electronic con-

trol units.

- Keep the antenna feeder line more than 20 cm (8 in) away

from the harness of electronic controls.
Do not let them run parallel for a long distance.

- Adjust the antenna and feeder line so that the standingwave

radio can be kept smaller.

- Be sure to ground the radio to vehicle body.

ENGINE RUNNING

• No work should be carried out on the hydraulic system while engine is running.
• Remember that fuel pressure values in hydraulic circuit can reach up to 1,600 bar.
• Keep hands or face (particularly eyes) out of any high pressure leak.
• Recall that fuel is dangerous for health.

FUEL RAIL PRESSURE SENSOR

• Under warranty, do not remove the fuel rail pressure sensor from the rail.
• Do not try to measure the resistance of the fuel rail pressure sensor. This test is destructive for the

internal components.

FUEL INJECTOR

• Fuel injectors are driven by over 100V.
• FUEL injector electronics are polarised. In case of intervention on wiring harness, do not

invertwires. It is destructive for the piezo components.

• Do not drive the fuel injectors if their body is not connected to the battery ground (risk ofelectro-

static discharge). For instance, fuel injector body have to be in contact with cylinder.

• Piezo fuel injector connector must not be unplugged while engine is running. Risk of majordamage

to the engine (fuel injector could stay opened).

Cleanliness

RISKS ASSOCIATED WITH CONTAMINATION

The high pressure direct injection system is highly sensitive to contamination. The risks associated with con-
tamination are:
• damage to or destruction of the high pressure injection system,
• components jamming,
• components losing seal integrity.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the fuel injectors.
What are the sources of contamination?
• metal or plastic chips,
• paint,
• fibres:
- from cardboard,
- from brushes,
- from paper,
- from clothing,
- from cloths,
• foreign bodies such as hair,
• ambient air
• etc.
NOTE:
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create electrical connection malfunction.

INSTRUCTIONS TO BE FOLLOWED BEFORE CARRYING OUT ANY WORK

JMBIA0432ZZ

EC-812

< PRECAUTION >

[K9K]

PRECAUTIONS

NOTE:
Before any work is carried out on the high pressure injection system, protect:
• the accessories and timing belts,
• the electrical accessories, (starter, alternator, electric power assisted steering pump),
• the flywheel surface, to prevent any diesel from running onto the clutch friction plate.

• Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department).

The plugs are single-use only. After use, they must be discarded (once used they are soiled and cleaning is
not sufficient to make them reusable). Unused plugs must be discarded.

• Check that you have hermetically resealable plastic bags for storing removed parts. Stored parts will there-

fore be less subject to the risk of impurities. The bags are to be used once only, and discarded after use.

• Use lint-free cleaning cloths. Using normal cloth or paper is prohibited. They are not lint-free and could con-

taminate the fuel circuit. Each cloth should only be used once.

• Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncon-

taminated container.

• For each operation, use a clean brush in good condition (the brush must not shed its bristles).
• Use a brush and cleaning agent to clean the unions to be opened.
• Blast compressed air over the cleaned parts (tools, workbench, the parts, unions and injection system

zones). Check that no bristles remain.

• Wash your hands before and during the operation if necessary.
• When wearing leather protective gloves cover them with latex gloves to prevent contamination.

INSTRUCTIONS TO BE FOLLOWED WHEN CARRYING OUT ANY WORK

• As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.

The plugs to be used are available from the Parts Department. The plugs must not be reused under any cir-
cumstances.

• Seal the pouch shut, even if it has to be opened shortly afterwards. Ambient air carries contamination.
• All components removed from the injection system must be stored in a hermetically sealed plastic bag once

they have been plugged.

• Using a brush, cleaning agent, air gun, sponge or normal cloth is strictly prohibited once the circuit has been

opened. These items could allow contamination to enter the system.

• A new component replacing an old one must not be removed from its packaging until it is to be fitted to the

vehicle.
