U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009464841
CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication
line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control units , 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, CAN-L) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.
CAN communication signal chart. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
ITS COMMUNICATION
• ITS communication is a multiplex communication system . This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with 2 communication lines.
• ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.

DOOR LOCK FUNCTION
Door Lock and Unlock Switch
• The door lock and unlock switch (driver side) is built into power window main switch.
• The door lock and unlock switch (passenger side) is built into front power window switch (passenger side).
• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are
locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors are
unlocked.
Door Key Cylinder Switch
• With the mechanical key inserted in the door key cylinder on driver side, turning it to lock position locks door
lock actuators of all doors.
• With the mechanical key inserted in the door key cylinder on driver side, turning it to unlock position once
unlocks the driver side door, turning it to unlock pos ition again within 60 seconds after the first unlock opera-
tion unlocks all of the other door act uators. (SELECTIVE UNLOCK OPERATION)
Selective unlock operation mode can be changed using CONSULT.
Refer to BCS-15, "DOOR LOCK : CONSULT Function (BCM - DOOR LOCK)"
.

tem Description".
IGNITION POSITION WARNING FUNCTION
When door lock and unlock switch are operated while driv er side door is open and ignition position is ACC or
ON, door locks once but immediately unlocks.
INTERIOR ROOM LAMP CONTROL FUNCTION
Interior room lamp is controlled according to door lock/unlock state, refer to INL-7, "System Description".
AUTOMATIC DOOR LOCK/UNLOCK FUNCTION (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed or shift posi-
tion. It has 2 types as per the following items.
Vehicle Speed Sensing Auto Door Lock
All doors are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 24 km/h (15 MPH) or more.

OPERATION DESCRIPTION
• When the BCM detects that each door request switch (if equipped) is pressed, it activates the outside key
antenna and inside key antenna corresponding to the pres sed door request switch (if equipped) and trans-
mits the request signal to the Intelligent Key. T hen check that the Intelligent Key is near the door.
• If the Intelligent Key is within the outside key ant enna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM locks/unlocks each door.
• BCM sounds Intelligent Key warning buzzer (lock: 2 ti mes, unlock: 1 time) and blinks hazard warning lamps
(lock: 2 times, unlock: 1 time) at the same time as a reminder.
OPERATION CONDITION
If the following conditions are satisfied, door lock/unl ock operation is performed if the door request switch (if
equipped) is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be locked/unlocked from outside of the v ehicle with
a spare Intelligent Key as long as key IDs are different.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver, passenger door handles (1) and rear bumper (2). However,
this operating range depends on the ambient conditions.
SELECTIVE UNLOCK FUNCTION
Lock Operation
When a LOCK signal is sent from door r equest switch (if equipped), all doors are locked.
Unlock Operation
• When an UNLOCK signal from driver side door request swit ch (if equipped) is transmitted, driver side door is
unlocked. When another UNLOCK signal is transmitted within 60 seconds, all other doors are unlocked.
• When an UNLOCK signal from passenger side door reques t switch (if equipped) is transmitted, passenger
side door is unlocked. When another UNLOCK signal is transmitted within 60 seconds, all other doors are
unlocked.
How To Change Selective Unlock Operation Mode
Selective unlock operation mode can be changed using CONSULT.
Refer to BCS-22, "INTELLIGENT KEY : CONSUL T Function (BCM - INTELLIGENT KEY)"
.
HAZARD AND BUZZER REMINDER FUNCTION
During lock or unlock operation by each door request switch (if equipped), the hazard warning lamps and Intel-
ligent Key warning buzzer blinks or honks as a reminder.

REMOTE KEYLESS ENTRY FUNCT ION : System DescriptionINFOID:0000000009461781
The Intelligent Key has the same functions as the remote control entry system. Therefore, it can be used in the
same manner as the remote controller by operating the door lock/unlock button.
OPERATION
Remote keyless entry system controls operation of the following items.
• Door lock/unlock function
• Selective unlock function
• Auto door lock function
• Hazard and horn reminder function
• Trunk lid open function
• Remote engine start
OPERATION AREA
The remote engine start operating range is appr oximately 60 m (197 ft) from the vehicle.
REMOTE ENGINE START FUNCTION
• When the lock button and then the remote engine start butt on of the Intelligent Key are pressed within 5 sec-
onds of each other, a start signal is transmitted from Intelligent Key to BCM via remote keyless entry
receiver.
• When the BCM receives the remote engine start signal , it locks all doors, flashes the hazard lamps and
chirps the horn and the engine will then start.
• To exit the remote engine start mode from inside t he vehicle, depress the brake pedal and press the push-
button ignition switch at the same time.
• To cancel the remote engine start mode away from t he vehicle, press the remote engine start button on the
Intelligent Key.
• Once the vehicle has been started using the remote engi ne start feature it will remain running for 10 minutes.
Extended run time can be added to the initial 10 minute running time by pressing the lock button and remote
engine start button within 5 seconds of each other. Th is will add an additional 10 minutes of running time.
Extended time can only be added once, for a total run time of up to 20 minutes.
DOOR LOCK/UNLOCK FUNCTION
• When door lock/unlock button of the Intelligent Key is pr essed, lock signal or unlock signal transmitted from
Intelligent Key to BCM via remote keyless entry receiver.
