DOOR LOCK FUNCTION : System DescriptionINFOID:0000000003794743
Only 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 activates the outside key antenna and
inside key antenna corresponding to the pressed door request switch and transmits the request signal to the
Intelligent 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 lock/unlock each door and sounds Intelligent Key warning buzzer (lock: 2 time, unlock: 1 times) at the
same time as a reminder.
OPERATION CONDITION
If the following conditions are satisfied, door lock/unlock operation is performed when the request switch is
operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.

U1000 CAN COMM CIRCUIT
BCM
BCM : DescriptionINFOID:0000000003794769
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 detectability. Modern vehi-
cles are 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-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.
CAN Communication Signal Chart. Refer to LAN-22, "
CAN Communication Signal Chart".
