SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Revision: 2006 July 2007 FX35/FX45
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger room.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

4. Remove instrument driver lower panel. Refer to IP-11, "Removal and Installation" .
5. After the bolt of the case with the air cleaner is disconnected, and it is moved, the cable is pulled.
6. Remove the grommet on the dashboard, and pull the hood lock cable toward the passenger room. CAUTION:
While pulling, be careful not to damage (peeling) the outside of the hood lock cable.
INSTALLATION
1. Pull the hood lock cable through the panel hole to the engine room.
Be careful not to bend the cable too much, keeping the radius
100 mm (3.94 in) or more.
2. Make sure the cable is not offset from the positioning grommet, and push the grommet into the panel hole securely.
3. Apply the sealant to the grommet (at * mark) properly.
4. Install the cable securely to the lock.
5. After installing, check the hood lock adjustment and hood opener operation.
Hood Lock Control InspectionNIS001LQ
CAUTION:
If the hood lock cable is bent or deformed, replace it.
1. Make sure that the hood lock secondary latch is properly engaged with the secondary striker with hood's own weight.
2. Make sure that the hood lock primary latch is securely engaged with the hood striker with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81 in) or
more.
3. When pulling hood opener lever gently, make sure that front end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch are disengaged. Also make sure that hood
opener returns to the original position.

INTELLIGENT KEY SYSTEM
Revision: 2006 July 2007 FX35/FX45
System DescriptionNIS001N6

The Intelligent Key system is a system which can lock and unlock the doors (door lock function) and start
the engine (engine start function) by carrying around the Intelligent Key, which operates based on the
results of electrical key-ID verification using two-way communications between the Intelligent Key and the
vehicle

Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote control entry system. (Remote control entry functions)

As an ignition key warning function, when a door is locked or unlocked with entry switch or remote control-
ler button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.

Even if the vehicle or Intelligent Key battery runs down, the door can be locked and unlocked and the
engine started with the mechanical key built into the Intelligent Key.

If an Intelligent Key was 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, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK FUNCTION
Operation Description

When the driver door, passenger door, or back door request switch is pressed, Intelligent Key unit sends a
request signal from the transmission antenna corresponding to the pressed door request switch, key-ID
verification is performed using two-way communication with Intelligent Key, and if ID is successfully veri-
fied, a door lock/unlock request signal is sent to BCM (Body Control Module) using CAN communication
to lock/unlock the door lock.

When door is locking, door is unlocked, when door is unlocking, door is locked.

When door is locked/unlocked by door request switch operation, hazard lamps flash and Intelligent Key
warning buzzer sounds.

With the locking operation of door request switch, door lock actuators of all door are locked.
