Precautions Necessary for Steering Wheel Rotation After Battery DisconnectABS00B3J
NOTE:

This Procedure is applied only to models with Intelligent 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-II 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 power 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-II.
Precautions for Drain Engine Coolant and Engine OilABS00E3J
Drain engine coolant and engine oil when the engine is cooled.
Precautions for Disconnecting Fuel PipingABS00E3K

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.
Precautions for Removal and DisassemblyABS00E3L

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.

Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
make sure that dowel pins are installed in the original position.

Cover openings of engine system with a tape or equivalent, if necessary, to seal out foreign materials.

Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-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, do exactly as specified. Power tools may be
used in the step.
Precautions for Inspection, Repair and ReplacementABS00E3M
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.

e. Tighten mounting bolts in numerical order as shown in the fig-
ure.

There are two type mounting bolts. Refer to the following for
locating bolts.
f. After all bolts are tightened, retighten them to the specified torque in numerical order shown in the figure.

If liquid gasket protrudes, wipe it off immediately.
g. After installing rear timing chain case, check the surface height difference between the following parts on the oil pan (upper)
mounting surface.

If not within the standard, repeat the installation procedure.
3. Install water pump with new O-rings. Refer to CO-22, "
WATER PUMP" .
4. Make sure that dowel pin hole, dowel pin and crankshaft key are located as shown in the figure. (No. 1 cylinder at compression
TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
CAUTION:
Hole on small dia. side must be used for intake side dowel pin hole. Do not misidentify (ignore big
dia. side).
5. Install timing chains (secondary) and camshaft sprockets as follows: CAUTION:
Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions
repeatedly during the installation process. Bolt length: Bolt position
