PRECAUTIONS
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001524895
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-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 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-III.
Precaution for Drain Engine Coolant and Engine Oil
INFOID:0000000001325752
Drain engine coolant and engine oil when engine is cooled.
Precaution for Disconnecting Fuel Piping
INFOID: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 Disassembly
INFOID: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 equivalent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized 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, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and Replacement
INFOID:0000000001325755
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
