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

PRECAUTIONS
4. Cover the serrated end of the valve with a large shop towel (A).
Strike the valve face end with a hammer, separating it into two
pieces.
5. Fill a bucket, such as a 20 (5-1/4 US gal, 4-3/8 Imp gal) oil can, with at least 10 (2-5/8 US gal, 2-1/4 lmp gal) of water.
Carefully place the already cut (serrated) valves into the water
one-at-a-time using a set of large tweezers and quickly move
away at least 2.7 m (9 ft).
6. The valves should be placed in a standing position as shown in the illustration to allow complete reaction. After the bubbling
action has subsided, additional valves can be placed into the
bucket allowing each subsequent chemical reaction to subside.
However, no more than 8 valves should be placed in the same
10 (2-5/8 US gal, 2-1/4 lmp gal) amount of water. The com-
plete chemical reaction may take as long as 4 to 5 hours.
Remove the valves using a set of large tweezers after the chem-
ical reaction has stopped. Afterwards, valves can be disposed
as ordinary scrap.
Precaution for Assembly and InstallationINFOID:0000000009460458
• Use torque wrench to tighten bolts or nuts.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
follow the specifications.
• Always replace the old with a new gas ket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• Bleed the air trapped within the system after draining the coolant.
• Before starting engine, apply fuel pressure to fuel li nes with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage or rattles.
Parts Requiring Angular TighteningINFOID:0000000009460459
• Use an angle wrench for the final tightening of the following engine parts.
- Cylinder head bolts
- Lower cylinder block bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
• Do not use a torque value for final tightening.
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.

CHECKING COMPRESSION PRESSURE
1. Warm up the engine to full operating temperature.
2. Release the fuel pressure. Refer to EC-182, "Work Procedure"
.
3. Remove the ignition coil and spark plug from each cylinder. Refer to EM-40, "Removal and Installation"
.
4. Connect engine tachometer (not required in use of CONSULT).
5. Disconnect the fuel injector harness connector to avoid any residual fuel injection during the measure- ment.
6. Install the compression tester with the adapter into the spark plug hole.
• Use compression tester whose end (a) (rubber portion) is smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be caught by
cylinder head during removal.
7. With the accelerator pedal fully depressed, turn the ignition switch to the “START” position to crank over
the engine. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform
these steps to check each cylinder.
Unit: kPa (kg/cm2, psi) / rpm
CAUTION:
Always use a fully charged battery to ob tain specified engine cranking speed.
• If the engine speed is out of specified rpm range, check the battery. Check engine speed again with a fully
charged battery.
• If compression pressure is below minimum value, check valve clearances and parts associated with com- bustion chamber (valve, valve seat, piston, piston ri ng, cylinder bore, cylinder head, cylinder head gasket).
After the checking, measure compression pressure again.
• If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole of the cylinder to re-check it for compression.
• If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the pis- ton rings and replace if necessary.
• If the compression pressure remains at low level des pite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the valve or valve seat accordingly.
