INTELLIGENT KEY SYSTEM
Warning Procedure
CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-III or Intelligent Key operation.
Changing Settings With the Intelligent Key
Warning for take out of Intelligent
Key to outside the car (from win-
dow) When the ignition knob is pressed in so that it can be rotated (or has been rotated), if the
vehicle speed is no greater than 5 km per hour, the Intelligent Key unit compares the key-ID
with that of the Intelligent Key every 30 seconds using the inside key antenna, if the results
of the comparison are NG (the Intelligent Key is not found)
Note: The factory setting for this function is OFF.
Door lock non-operation warningWhen any of the following conditions are met
Intelligent Key Lock-in Prevention Warning
 When the Intelligent Key is inside the car and the ignition knob is not pressed, when an
attempt is made to lock a door lock with a door request switch
NOTE:
This warning is issued even if the Intelligent Key is not in the out side key antenna detec-
tion area corresponding to the door request switch was operated.
Knob Return Forgotten Warning
 When the ignition knob is pressed, when an attempt is made to lock a door lock with a door
request switch
NOTE:
This warning is only issued if the Intelligent Key is in the out side key antenna detection
area corresponding to the door request switch was operated.
Door Ajar Alarm
 When any of the doors is open, when an attempt is made to lock a door lock with a door
request switch
NOTE:
This warning is only issued if the Intelligent Key is in the out side key antenna detection
area corresponding to the door request switch was operated.
Intelligent Key low battery pre-warn-
ing This warning is issued when it is detected that the battery in the Intelligent Key has been
used up.

Intelligent Key remote controller button and door reques t switch operations change the engine startup function
settings (startup enabled/disabled) for each Intelligent Key independently.
Settings Change Procedure1. With the ignition switch is in the LOCK positi on (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-III
The settings for the Intelligent Key system func tions can be changed using CONSULT-III (WORK SUPPORT).
Refer to BL-104, "
CONSULT-III Application Item".
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
Changing Settings Using Display Unit
The settings of the Intelligent Key system can be changed, using CONSULT-III, display unit, Intelligent Key
and door request switch in the cent er of the instrument panel.
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 executed using the CONSULT-III. Up to 4 can be registered.
CAUTION:
 After a new Intelligent Key-ID is regi stered, 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-III can be used to check and delete Intelligent Key-IDs.
For future information, see the CO NSULT-III Operation Manual NATS.
STEERING LOCK UNIT REGISTRATION
Steering Lock Unit ID Registration
CAUTION:
 The method for registering a steering lock unit ID depends on the status of the steering lock unit and
Intelligent Key unit (new or old unit).
 After registration is completed, press ignition knob with a portable unit in the vehicle so that it can
be rotated, and confirm that it cannot be rotated even when ignition switch is pressed without a por-
table unit in the vehicle.
For further information, see the CONS ULT-III Operation Manual NATS.
CAN Communication System DescriptionINFOID:0000000001327838
CAN (Controller Area Network) is a serial communication li ne 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.
Setting item Description
Intelligent Key Lock Response-Sound The sound pattern of the Intelligent Key operation can be set as desired. (Setting value:
OFF, Beeper or Horn chirp)
Intelligent Key Unlock Response-Beep
Sound The beep sound when unlocking door with the Intelligent Key operation can be turned ON
or OFF.
Intelligent Key Engine Start Function This function can be performed to ON or OFF.
Intelligent Key Lock/Unlock Function The door handle request switch lock/unlock operation with the Intelligent Key can be can-
celed or activated.
Return All Settings to Default The all settings made by VEHICLE ELECTRONICS will return to default.

DTC P0335 CKP SENSOR (POS)
Component DescriptionINFOID:0000000001326141
The crankshaft position (CKP) sensor (POS) is located on the oil pan
facing the gear teeth (cogs) of the si
gnal plate. It detects the fluctua-
tion of the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic fiel d, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.

TESTING CONDITION:
Before performing the following procedure, confirm th at battery voltage is more than 10.5V with igni-
tion switch ON.
1. Crank engine for at least 2 seconds and run it for at least 5 seconds at idle speed.
2. Check 1st trip DTC.

CMP SENSOR (PHASE)
DTC P0340, P0345 CMP SENSOR (PHASE)
Component DescriptionINFOID:0000000001326149
The camshaft position (CMP) sensor (PHASE) senses the retraction
of camshaft (INT) to identify a particular cylinder. The camshaft posi-
tion sensor (PHASE) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoper-
ative, the camshaft position sensor (PHASE) provides various con-
trols of engine parts instead, utilizi ng timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.
ECM receives the signals as shown in the figure.
