PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012431679
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 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 inoper ative, 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 NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.

COMPRESSION PRESSURE
InspectionINFOID:0000000012431691
1. Warm up engine to full operating temperature and then turn it off.
2. Release fuel pressure. Refer to
EC-137, "
Work Procedure".
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-48, "
Exploded View".
4. Connect engine tachometer (not required in use of CONSULT).
5. Install compression gauge (B) with an adapter (A) into spark plug hole.
• Use an adapter with a diameter (a) smaller than 20 mm (0.79in). Otherwise, it may be caught by cylinder head during
removal.
6. With accelerator pedal fully depressed, turn ignition switch to »»» for cranking. When the gauge pointer stabilizes, read the compression pressure and the engi ne rpm. Perform these steps to check each cylin-
der.
CAUTION:
Always use a fully charged battery to obtain the specified engine speed.
• If the engine speed is out of the specified range, check the battery. Check the engine speed again with a
fully charged battery.
• If some cylinders have low compression pressure, pour a small amount of engine oil into the spark plug hole to recheck the compression.
- If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the piston rings and replace if necessary.
- If the compression pressure remains low despite the addition of engine oil, the valves may be malfunc-
tioning. Check the valves for damage. Replace the valve or valve seat as necessary.
• If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil the head gasket may be leaking, or valves in adjacent cylinders
may be damaged. Inspect and repair as required.
• If the compression pressure is below the minimum value, check the valve clearances and parts associ-
ated with the combustion chamber (valve, valve seat , piston, piston ring, cylinder bore, cylinder head,
cylinder head gasket). After repairing, measure the compression pressure again.
7. After inspection is completed, install removed parts.
8. Start the engine, and ensure that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-120, "
Work Flow".

INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
