SQUEAK AND RATTLE TROUBLE DIAGNOSES
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. 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. 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.

INTELLIGENT KEY SYSTEM
System DescriptionBIS000WZ
The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (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 Intelli-
gent Key and the vehicle
Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote keyless entry system. (Remote keyless entry functions)
As an ignition key warning function, when a door lock is locked or unlocked with request switch or remote
controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.
Even if the Intelligent Key battery runs down, the door locks can be locked and unlocked and the engine
started with the mechanical key built into the Intelligent Key.
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, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK/UNLOCK, TRUNK OPEN FUNCTION
Operation Description
When the driver door, passenger door, or trunk open request switch is pressed, Intelligent Key unit sends
a request signal from the outside key antenna corresponding to the pressed request switch, key-ID verifi-
cation is performed using two-way communication with Intelligent Key, and if ID is successfully verified, a
door lock/unlock request signal is sent to BCM 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 lock 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.
When trunk open request switch is pushed, trunk lid is opened.
Operation Condition
Auto Door Lock Function
After the door request switch in the driver or passenger door is operated and the vehicle door locks are
unlocked, all the doors are automatically locked unless the mechanical key is inserted into the ignition knob,
the ignition knob is pressed, any door request switch is pressed, any one of the doors is opened, or an Intelli-
gent Key remote control button is operated within 2 minutes.
Hazard Reminder Function
The hazard lamps are flashed when the door lock is locked or unlocked by door request switch operation.
When ignition switch ON or any door is opened, key reminder function is not operate.

Hazard Reminder Function
The hazard lamps are flashed when the door lock is locked or unlocked by remote controller button.
When ignition switch ON or any door is opened, key reminder function is not operate.
List of Operation Related Parts
Parts marked with × are the parts related to operation.
ENGINE START FUNCTION
Operation Description
When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID
verification is performed with Intelligent Key using two-way communication, and if verification is success-
ful, an ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit
releases ignition knob rotation prohibition latch. (Ignition knob can now be turned.)
When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights
up red.
When key-ID verification is successful, Intelligent Key unit uses CAN communication to send engine start
permission signal to BCM.
When BCM receives engine start permission signal, it uses CAN communication to sent starter request
signal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the vehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, trunk room or in glove box.

INTELLIGENT KEY SYSTEM
CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II or Intelligent Key operation.
Changing Settings With the Intelligent Key
Intelligent Key remote controller button and door request switch operations change the engine startup function
settings (startup enabled/disabled) for each Intelligent Key independently.
Settings Change Procedure
1. With the ignition switch is in the LOCK position (ignition knob not pressed), hold down both the LOCK and
UNLOCK remote control buttons on the Intelligent Key at the same time for at least 10 seconds (The yard-
stick is that the Intelligent Key LED flashes 20 times.)
2. Within 5 seconds of releasing the Intelligent Key remote controller buttons, press the driver door request
switch.
3. The KEY warning lamp in combination meter lights up for 3 seconds (engine starting enabled → starting
disabled: lights up red, engine starting disabled → flashes green). This completes the settings change.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-94, "
WORK SUPPORT" .
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is performed using the CONSULT-II. Up to 4 can be registered.
CAUTION:
After a new Intelligent Key-ID is registered, be sure to check the function.
When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-II can be used to check and delete Intelligent Key-IDs.
For future information, see the CONSULT-II Operation Manual NATS.
