DescriptionINFOID:0000000009462866
FUEL CUT CONTROL (AT NO LOAD AND HIGH ENGINE SPEED)
If the engine speed is above 2,000 rpm under no load (for ex
ample, the selector lever position is P or N and
engine speed is over 2,000 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off var-
ies based on engine speed.
Fuel cut will be operated until the engine speed reaches 1,100 rpm, then fuel cut will be cancelled.
NOTE:
This function is different from deceleration contro l listed under Multiport Fuel Injection (MFI) System, EC-568,
"MULTIPORT FUEL INJECTION SYSTEM : System Description".

EVAP LEAK CHECK
EVAP LEAK CHECK
Work ProcedureINFOID:0000000009462869
CAUTION:
• Never use compressed air or a high pressure pump.
• Never exceed 4.12 kPa (0.042 kg/cm
2, 0.6 psi) of pressure in EVAP system.
NOTE:
• Do not start engine.
• Improper installation of EVAP service port adapter (com mercial service tool) to the EVAP service port may
cause a leakage.
WITH CONSULT
1. To locate the EVAP leakage, install EVAP service port adapter (commercial service tool) and pressure pump to EVAP service
port.
2. Turn ignition switch ON.
3. Select the “EVAP SYSTEM CLOSE” of “WORK SUPPORT MODE” with CONSULT.
4. Touch “START”. A bar graph (Pressure indicating display) will appear on the screen.
5. Apply positive pressure to the EVAP system until the pressure indicator reaches the middle of the bar graph.
6. Remove EVAP service port adapter (commercial service tool) and hose with pressure pump.
7. Locate the leakage using a leakage detector (commercial ser- vice tool). Refer to EC-580, "EVAPORATIVE EMISSION SYS-
TEM : System Description".
WITHOUT CONSULT
1. To locate the EVAP leakage, install EVAP service port adapter
(commercial service tool) and pressure pump to EVAP service
port.
2. Apply battery voltage between the terminals of EVAP canister vent control valve to ma ke a closed EVAP system.
3. To locate the leakage, deliver positive pressure to the EVAP sys- tem until pressure gauge points r each 1.38 to 2.76 kPa (0.014 to
0.028 kg/cm
2, 0.2 to 0.4 psi).
4. Remove EVAP service port adapter (commercial service tool) and hose with pressure pump.

POSITIVE CRANKCASE VENTILATION
Work ProcedureINFOID:0000000009462870
1.CHECK PCV VALVE
With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace PCV valve.

PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951675
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 the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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 Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 minutes before performing any service.
Precaution for Draining CoolantINFOID:0000000009460453
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460454
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before any removal or disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460455
• When instructed to use special service tools, use the s pecified tools. Always be careful to work safely, avoid
forceful operations.
• Use maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or equivalent , if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organi zed way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, follow the specifications.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460456
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
