SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
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 compartment.
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.

CAN Communication System DescriptionNIS001WR
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

INTELLIGENT KEY SYSTEM
Revision: 2006 January2006 M35/M45
System DescriptionNIS001X8
The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), open the trunk (trunk open function), and start the engine (engine start function) by carry-
ing around the Intelligent Key (without some key operation), which operates based on the results of elec-
tronic ID verification using two-way communications between the Intelligent Key and the vehicle
(Intelligent Key unit).
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 controller 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, unlocked or trunk open with request switch or remote controller button opera-
tion, the hazard lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/
horn reminder function).
Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked
with the mechanical key built into the Intelligent Key, and then initiates engine by inserting Intelligent Key
into key slot.
The settings for each function can be changed with the CONSULT-II.
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-II.
DOOR LOCK/UNLOCK/TRUNK OPEN FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door and open the trunk by carry-
ing around the Intelligent Key (without some key operation).
System Diagram
Operation Description/Door Lock/Unlock
When the Intelligent Key unit detects that each door request switch is pressed, it starts the outside key
antenna and inside key antenna corresponding to the pressed door request switch and sends the request
signal to the Intelligent Key. And then, make sure that the Intelligent Key is near the 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 via remote keyless entry receiver.
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 buzzer warning (lock: 1
time, unlock: 2 times) at the same time.

Selective Unlock Function
When an LOCK signal is sent from door request switch (driver side or passenger side), all doors will be locked.
When an UNLOCK signal is sent from door request switch (driver side or passenger side) once, driver's door
will be unlocked.
Then, if an UNLOCK signal is sent from door request switch (driver side and passenger side) again within 5
seconds, all other door will be unlocked.
Hazard and Buzzer Reminder Function
During lock, unlock, or trunk opening operation by each request switch, the hazard warning lamps and Intelli-
gent Key warning buzzer will flashes or honk as a reminder.
When doors are locked, unlocked or trunk open by each request switch, Intelligent Key unit honks Intelligent
Key warning buzzer as a reminder and sends hazard request signal to BCM via CAN communication line.
