Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009976114
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.
On Board Diagnosti c (OBD) System of Engine and CVTINFOID:0000000009462476
The ECM has an on board diagnostic system. It will illuminate the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
• Always to turn the ignition swit ch OFF and disconnect the negative battery cable before any repair
or inspection work. The open/short circuit of re lated switches, sensors, solenoid valves, etc. will
cause the MIL to illuminate.
• Always to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to illuminate due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For descrip tion and how to disconnect, refer to PG-65, "Description"
.
• Always route and secure the harnesses properly afte r work. The interference of the harness with a
bracket, etc. may cause the MIL to illu minate due to the short circuit.
• Always to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to illuminate due to the malfuncti on of the EVAP system or fuel injection system,
etc.
• Always to erase the unnecessary malfunction informati on (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.

• 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.

CRANKSHAFT RUNOUT
• Place a V-block on a precise flat table to support the journals on
both ends of the crankshaft.
• Place a dial gauge (A) straight up on the No. 3 journal.
• While rotating the crankshaft, read the movement of the pointer on the dial gauge (A), the total indicator runout reading.
OIL CLEARANCE OF CONNECTING ROD BEARING
Method of Measurement
• Install the connecting rod bearings (2) to the connecting rod (3)
and the cap (1), and tighten the c onnecting rod bolts to the speci-
fied torque. Using a inside micrometer measure the inner diameter
of connecting rod bearing (B).
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)
• If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing. Refer
to EM-105, "How to Select Piston and Bearing"
.
Method of Using Plastigage
• Remove oil and dust on the crankshaft pin and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
• Install the connecting rod bearings to the connecting rod cap, and tighten the connecting rod bolts to the specified torque.
CAUTION:
Do not rotate the crankshaft.
• Remove the connecting rod cap and bearings, and using the scale on the Plastigage bag, measure the Plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the method by calculation.
OIL CLEARANCE OF MAIN BEARING
Method of Measurement
• Install the main bearings to the cylinder block and bearing cap. Measure the main bearing inner diameter with the bearing cap bolt tightened to the specified torque.
(Oil clearance) = (Inner diameter of main beari ng) – (Outer diameter of crankshaft journal)
• If the measured value exceeds the limit, select main bearings referring to the main bearing inner diameter
and crankshaft journal outer diameter, so that t he oil clearance satisfies the standard. Refer to EM-105,
"How to Select Piston and Bearing".
