INTELLIGENT KEY SYSTEM
System Description
INFOID:0000000001703999
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start function) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).
• Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col-
umn to prevent accidental shut-off of the ignition switch and locking of the steering wheel during driving con-
dition when the vehicle is moving.
CAUTION:
The driver should always carry the Intelligent Key
• Operation of the remote controller buttons on the Intelligent Key also provides the same functions as the
remote control entry system. (Remote keyless entry functions)
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).
• Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked and
the engine started with the mechanical key built into the Intelligent Key.
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
• It has been made possible to diagnose the system and register an Intelligent Key with the CONSULT-III.
DOOR LOCK/UNLOCK FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door by carrying around the Intelli-
gent Key (without some key operation).
System Diagram
Operation Description
• When the Intelligent Key unit detects that each request switch is pressed, it starts the outside key antenna
and inside key antenna corresponding to the pressed request switch and sends the request signal to the
Intelligent Key. And then, make sure that the Intelligent Key is near door.
• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and
sends the key ID signal to the Intelligent Key unit.
• Intelligent Key unit receives the key ID signal and compares it with the registered key ID.
• If the key ID check result is OK, the Intelligent Key unit sends the door lock/unlock request signal to BCM
(Body control module) via CAN communication line.
• Intelligent Key unit sends the door lock/unlock signal and sounds Intelligent Key warning buzzer (lock: 2
times, unlock: 1 time) at the same time.
• When BCM receives the door lock/unlock signal, it operates door lock actuator and flashes the hazard warn-
ing lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition
If the following conditions are not satisfied, door lock/unlock operations are not performed even if the request
switch is operated.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703818
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, 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 NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Brake SystemINFOID:0000000001703819
CAUTION:
• Refer to MA-10
for recommended brake fluid.
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake
tube.
• If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF and remove the connector of the
ABS actuator and electric unit (control unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surfaces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to BR-28, "
Brake Burnishing Proce-
dure".
WARNING:
• Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000001703821
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
engine compartment. This is normal due to the self check operation.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
