CAN Communication System DescriptionINFOID:0000000001327814
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.

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.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
When headlamp high relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied
to headlamps (LH and RH) and horns (HIGH and LOW).
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the back door must be unlocked with the key, key fob or
Intelligent Key.
When the key is used to unlock a door, BCM terminal 22 receives signal
 from terminal 14 of the power window ma in switch (door lock and unlock switch).
When the BCM receives either one of these signals or unl ock signal from key cylinder switch, key fob or Intel-
ligent Key, the vehicle security sy stem is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operat e vehicle security system (horn and headlamps) as
required.
When the remote keyless entry system is triggered, ground is supplied intermittently from IPDM E/R terminals
38 and 60.
When headlamp relay (which built-in IPDM E/R) and hor n relay are energized and then power is supplied to
headlamps (LH and RH) and horns (HIGH and LOW).
The headlamp flashes and the hor n sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob or Intelligent
Key.
