Precaution Necessary for Steering W
heel Rotation After Battery Disconnect
INFOID:0000000001524895
NOTE:
This Procedure is applied only to models with In telligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the ″LOCK ″ position.
Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS /IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.
Precaution for Drain Engine Coolant and Engine OilINFOID:0000000001325752
Drain engine coolant and engine oil when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001325753
Before starting work, make sure no fire or spark producing items are in the work area.
Release fuel pressure before disconnecting and disassembly.
After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000001325754
When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.
Exercise maximum care to avoid damage to mating or sliding surfaces.
Cover openings of engine system with tape or the equival ent, 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, star t with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001325755
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.

Precaution for Assembly and InstallationINFOID:0000000001325756
Use torque wrench to tighten bolts or nuts to specification.
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,
do exactly as specified.
Replace with new gasket, packing, oil seal or O-ring.
Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for any restriction and blockage.
Guide pins are used for several parts alignment. When replacing and reassembling parts with guide pins, make sure that guide pins are installed in the original portion.
Avoid damaging sliding or mating surfaces. Completely re move foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
Release air within route when refilling after draining engine coolant.
After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Parts Requiring Angle TighteningINFOID:0000000001325757
Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angletightening)
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.
Precaution for Liquid GasketINFOID:0000000001325758
REMOVAL OF LIQUID GASKET SEALING
After removing mounting nuts and bolts, separate the mating sur- face using seal cutter (SST) and remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
Tap seal cutter to insert it, and then slide it by tapping on the side
as shown in the figure.
In areas where seal cutter (SST) is difficult to use, use plastic ham-
mer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reaso n tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur- face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.
Within five minutes of liquid gasket application, install the mat-
ing component.
If liquid gasket protrudes, wipe it off immediately.
Do not retighten after the installation.
Wait 30 minutes or more after installation before refilling engine with engine oil and engine coolant.
CAUTION:
If there are specific instruct ions in this manual, observe
them.
