Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNAS0008J
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 Procedures without Cowl Top CoverNAS00077
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionsNAS00078
Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to
properly ventilate the area before working with hazardous mate-
rials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.
When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
Battery posts, terminals and related accessories contain lead
and lead compounds. Wash hands after handling.
To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.
Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
Replace inner and outer races of tapered roller bearings and needle bearings as a set.
Arrange the disassembled parts in accordance with their assembled locations and sequence.
Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
Use only the fluids and lubricants specified in this manual.
Use approved bonding agent, sealants or their equivalents when required.
Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.
When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

PDU (POWER DISTRIBUTION UNIT)PFP:285F1
Component Parts and Harness Connector LocationNKS004ED
System DescriptionNKS004EE
PDU (Power Distribution Unit) is the unit that executes the power distribution with the control signal from
the Intelligent Key unit, instead of the mechanical power supply mechanism by conventional key cylinder.
The push-button ignition switch is operable when the Intelligent Key is within the detention area of the
interior antenna or is inserted to the key slot.
The push-button ignition switch operation is input to the Intelligent Key unit as a request signal. Then, the
Intelligent Key unit processes the request signal and orders the PDU to switch into the appropriate power
supply position.
NOTE:
The prerequisite for starting the engine varies by the state of brake pedal, A/T selector lever, and vehicle
speed.
PDU distributes power to each power supply circuit according to the request signal received.
The power supply position can be confirmed by illumination of the indicators in the upper surroundings of
the push-button ignition switch.
PUSH-BUTTON IGNITION SWITCH OPERATING PROCEDURE
The power supply position switching operation can be performed by the following operation.
NOTE:
When an Intelligent Key is within the detection area of inside antenna and when it is inserted to the key
slot, it is equivalent to the operations below.
When starting the engine, the Intelligent Key unit monitors the engine start conditions (brake pedal operat-
ing condition, A/T selector lever position, and vehicle speed).
Unless each start condition is fulfilled, the engine will not response regardless of how many times the
push-button ignition switch is pushed. At that time, illumination repeats the position in the order of LOCK
ACC ON LOCK.
