OUTLINE
Functions available by operating the inside door lock and unlock switches
• 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.
Functions available by operating the front door lock assembly LH (key cylinder switch)
• Interlocked with the locking operation of front door lock assembly LH (key cylinder switch), door lock actua-
tors of all doors are locked.
• When front door lock assembly LH (key cylinder switch) is unlocked, front door lock assembly LH (actuator)
is unlocked.
• When front door lock assembly LH (key cylinder swit ch) is unlocked for the second time within 5 seconds
after the first operation, front door lock assembly RH (actuator), rear door lock actuator LH and rear door
lock actuator RH are unlocked.
Key reminder door system
When door lock and unlock switch is operated to lock doors with ignition key inserted in key cylinder and any
door open, all door lock actuators are locked and then unlocked.
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed.
Vehicle Speed Sensing Auto Door Lock*1
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 15 MPH (24 km/h) or more.
If a door is opened and closed at any time during one ignition cycle (OFF → ON), even after initial auto door
lock has taken place, the BCM will relock all doors when the vehicle speed reaches 15 MPH (24 km/h) or more
again.
Setting change of Automatic Door Locks (LOCK) Function
The lock operation setting of the autom atic door locks function can be changed.
With CONSULT-III
The ON/OFF switching of the automatic door locks (LOC K) function and the type selection of the automatic
door locks (LOCK) function can be performed at the WO RK SUPPORT setting of CONSULT-III. Refer to BL-
41, "CONSULT-III Function (BCM)".
Without CONSULT- III
The automatic door locks (LOCK) function can be swit ched ON/OFF by performing the following operation.
