• BCM switches the status (control mode) by itself wit
h the power saving control function. It performs the sleep
request to each unit (IPDM E/R and combination mete r) that operates with the ignition switch OFF.
Normal mode (wake-up)- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
• The reading interval of each switch changes from 10 ms interval to 60 ms interval.
Sleep mode activation
• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
• Each unit stops the transmission of CAN communication with the sleep wakeup signal. BCM is in CAN com- munication sleep mode.
• BCM is in the low power consumption mode and perform s the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
• BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions are fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the
normal mode.
• Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the com- bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.

DOOR REQUEST SWITCH OPERATION
When pressing the request switch, it is possible to lock and unlock the door by carrying the Intelligent Key.
OPERATION DESCRIPTION
• When the BCM detects that each door request switch is pressed, it starts the outside key antenna and inside
key antenna corresponding to the pressed door request swit ch and transmits the request signal to the Intelli-
gent Key. And then, check 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
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 transmits door lock/unlock signal and operates each door lock actuator. At the same time, BCM blinks
hazard warning lamp (lock: 2 times, unlock: 1 time) and sounds Intelligent Key buzzer (lock: 1 time, unlock:
1 time) as a reminder.
OPERATION CONDITION
If the following conditions are satisfied, door lock/unl ock operation is performed if the door request switch is
operated:
Key reminder The key reminder buzzer sounds a warning if the door is locked with the key left
inside the vehicle. DLK-27
WarningIf an action that does not meet the operating condition of the Intelligent Key sys-
tem is taken, the buzzer sounds to inform the driver.
DLK-27
Engine start
The engine can be turned on while carrying the Intelligent Key. DLK-22
Interior room lamp control Interior room lamp is controlled according to door lock/unlock state. DLK-20

INFOID:0000000012430156
• Door lock actuator and unlock sensor are Integrated in front door
lock assembly LH.
• Door lock actuator receives lock/unlock signal from BCM, and then locks/unlocks driver door.
• Only front door lock assembly LH integrates unlock sensor. Unlock sensor transmits lock/unlock status of driver door to BCM.
3. BCM Then, when the ignition switch is turned ON, BCM
performs ID verification between BCM and ECM. If
the ID verification result is OK, ECM can start en-
gine.
Refer to BCS-77, "
BODY CONTROL SYSTEM :
Component Parts Location" for detailed installation
location.
4. Main power window and door lock/unlock switch Door lock and unlock switch is integrated into the
main power window and door lock/unlock switch.
Door lock and unlock switch transmits door lock/un-
lock operation signal to BCM.
Refer to PWC-7, "
Main Power Window And Door
Lock/Unlock Switch".
5. Front door lock assembly LH Door key cylinder switch is integrated into front door
lock assembly (driver side).
Door key cylinder switch detects door LOCK/UN-
LOCK operation using mechanical key, and then
transmits the operation signal to BCM.
Refer to DLK-194, "
REMOTE KEYLESS ENTRY
SYSTEM : Front Door Lock Assembly (Driver
Side)".
6. Rear door lock actuator LH Rear door lock actuator locks/unlocks the rear door
latch assembly.
