REMOVALNBBT0019S01After removing moldings, remove glass using piano wire or power
cutting tool and an inflatable pump bag.
WARNING:
When cutting the glass from the vehicle, always wear safety
glasses and heavy gloves to help prevent glass splinters from
entering your eyes or cutting your hands.
CAUTION:
IBe careful not to scratch the glass when removing.
IDo not set or stand the glass on its edge. Small chips may
develop into cracks.
INSTALLATIONNBBT0019S02IUse a genuine Nissan Urethane Adhesive Kit or equivalent
and follow the instructions furnished with it.
IWhile the urethane adhesive is curing, open a door win-
dow. This will prevent the glass from being forced out by
passenger compartment air pressure when a door is
closed.
IThe molding must be installed securely so that it is in
position and leaves no gap.
IInform the customer that the vehicle should remain sta-
tionary until the urethane adhesive has completely cured
(preferably 24 hours). Curing time varies with temperature
and humidity.
WARNING:
IKeep heat and open flames away as primers and adhesive
are flammable.
IThe materials contained in the kit are harmful if
swallowed, and may irritate skin and eyes. Avoid contact
with the skin and eyes.
IUse in an open, well ventilated location. Avoid breathing
the vapors. They can be harmful if inhaled. If affected by
vapor inhalation, immediately move to an area with fresh
air.
IDriving the vehicle before the urethane adhesive has com-
pletely cured may affect the performance of the wind-
shield in case of an accident.
CAUTION:
IDo not use an adhesive which is past its usable term.
Shelf life of this product is limited to six months after the
date of manufacture. Carefully adhere to the expiration or
manufacture date printed on the box.
IKeep primers and adhesive in a cool, dry place. Ideally,
they should be stored in a refrigerator.
IDo not leave primers or adhesive cartridge unattended
with their caps open or off.
IThe vehicle should not be driven for at least 24 hours or
until the urethane adhesive has completely cured. Curing
time varies depending on temperature and humidities. The
curing time will increase under higher temperatures and
lower humidities.

SBT191-A
Repairing Water Leaks for WindshieldNBBT0019S0301Leaks can be repaired without removing and reinstalling glass.
If water is leaking between the urethane adhesive material and
body or glass, determine the extent of leakage. This can be
done by applying water to the windshield area while pushing
glass outward.
To stop the leak, apply primer (if necessary) and then urethane
adhesive to the leak point.

Idle Air Volume LearningNBEC0642
SEF454Y
SEF455Y
DESCRIPTIONNBEC0642S01ªIdle Air Volume Learningº is an operation to learn the idle air vol-
ume that keeps each engine within the specific range. It must be
performed under any of the following conditions:
IEach time IACV-AAC valve, throttle body or ECM is replaced.
IIdle speed or ignition timing is out of specification.
PRE-CONDITIONINGNBEC0642S02Before performing ªIdle Air Volume Learningº, make sure that all of
the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are
missed for even a moment.
IBattery voltage: More than 12.9V (At idle)
IEngine coolant temperature: 70 - 99ÉC (158 - 210ÉF)
IPNP switch: ON
IElectric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime running light systems, if
the parking brake is applied before the engine is started the
headlamp will not illuminate.
ICooling fan motor: Not operating
ISteering wheel: Neutral (Straight-ahead position)
IVehicle speed: Stopped
ITransmission: Warmed-up
For A/T models with CONSULT-II, drive vehicle until ªFLUID
TEMP SEº in ªDATA MONITORº mode of ªA/Tº system indi-
cates less than 0.9V.
For A/T models without CONSULT-II, drive vehicle for 10 min-
utes.
OPERATION PROCEDURENBEC0642S03With CONSULT-IINBEC0642S03011. Turn ignition switch ªONº and wait at least 1 second.
2. Turn ignition switch ªOFFº and wait at least 10 seconds.
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic ªPRE-CONDITION-
INGº (previously mentioned) are in good order.
5. Turn ignition switch ªOFFº and wait at least 10 seconds.
6. Start the engine and let it idle for at least 30 seconds.
7. Select ªIDLE AIR VOL LEARNº in ªWORK SUPPORTº mode.
8. Touch ªSTARTº and wait 20 seconds.
9. Make sure that ªCMPLTº is displayed on CONSULT-II screen.
If ªINCMPº is displayed, ªIdle Air Volume Learningº will not be
carried out successfully. In this case, find the cause of the
problem by referring to the NOTE below.
10. Rev up the engine two or three times. Make sure that idle
speed and ignition timing are within specifications.
ITEM SPECIFICATION
Idle speed 750±50 rpm (in ªPº or ªNº position)
Ignition timing 15ɱ5É BTDC (in ªPº or ªNº position)

TROUBLE DIAGNOSIS Ð GENERAL DESCRIPTION
ECM Terminals and Reference Value (Cont'd)
EC-131

DescriptionNBEC0717The specification (SP) value indicates the tolerance of the value that is displayed in ªDATA MONITOR (SPEC)º
mode of CONSULT-II during normal operation of the Engine Control System. When the value in ªDATA MONI-
TOR (SPEC)º mode is within the SP value, the Engine Control System is confirmed OK. When the value in
ªDATA MONITOR (SPEC)º mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:
IB/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)
IA/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
IMAS A/F SE-B1 (The signal voltage of the mass air flow sensor)
Testing ConditionNBEC0718IVehicle driven distance: More than 5,000 km (3,100 miles)
IBarometric pressure: 101.3 kPa (760.0 mmHg, 29.92 inHg)±3 kPa (22.5 mmHg, 0.89 inHg)
IAtmospheric temperature: 20 - 30ÉC (68 - 86ÉF)
IEngine coolant temperature: 75 - 95ÉC (167 - 203ÉF)
ITransmission: Warmed-up*1
IElectrical load: Not applied*2
IEngine speed: Idle
*1: For A/T models, after the engine is warmed up to normal operating temperature, drive vehicle until ªFLUID
TEMP SEº (A/T fluid temperature sensor signal) indicates less than 0.9V.
*2: Rear window defogger switch, air conditioner switch, lighting switch are ªOFFº. Cooling fans are not oper-
ating. Steering wheel is straight ahead.
SEF601Z
Inspection ProcedureNBEC0719NOTE:
Perform ªDATA MONITOR (SPEC)º mode in maximum scale dis-
play.
1. Perform ªBasic Inspectionº, EC-101.
2. Confirm that the testing conditions indicated above are met.
3. Select ªB/FUEL SCHDLº, ªA/F ALPHA-B1º, ªA/F ALPHA-B2º
and ªMAS A/F SE-B1º in ªDATA MONITOR (SPEC)º mode with
CONSULT-II.
4. Make sure that monitor items are within the SP value.
5. If NG, go to ªDiagnostic Procedureº, EC-137.
