DOOR LOCK FUNCTION

Door Lock/Unlock Switch

Interlocked with the locking operation of door lock/unlock switch, door lock actuator of all doors and fuel filler lid lock actuator are locked.
Interlocked with the unlocking operation of door lock/unlock switch, door lock actuator of all doors and fuel filler lid lock actuator are unlocked.

INTERIOR ROOM LIGHT CONTROL FUNCTION

Interior room light is controlled according to door lock /unlock state, refer to 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 position. It has two types as per the following items.

Vehicle Speed Sensing Auto Door Lock

All doors are locked when the vehicle speed reaches 15 km/h (9 MPH) or more.

BCM outputs the lock signal to all door lock actuators when it detects all doors are closed and the vehicle speed received from the ABS actuator and electric unit (control unit) via CAN communication becomes 15 km/h (9 MPH) or more.

P Range Interlock Door Lock

All doors are locked when shifting the selector lever from any position other than the P to P position.

BCM outputs the lock signal to all door lock actuators when it detects the shift position signal received from TCM via CAN communication is shifted from any position other than the P to P position.

Setting Change of Automatic Door Lock Function

The lock operation setting of the automatic door lock function can be changed by combination meter setting.

AUTOMATIC DOOR LOCK/UNLOCK FUNCTION (UNLOCK OPERATION)

The automatic door lock/unlock function is the function that unlocks all doors linked with the key position or shift position. It has 2 types as per the following items.

IGN OFF Interlock Door Unlock

All doors are unlocked when the ignition position is changed from ON to OFF.

BCM outputs the unlock signal to all door lock actuators when it detects that the ignition position is changed from ignition switch ON to OFF.

P Range Interlock Door Unlock

All doors are unlocked when shifting the selector lever from any position other than the P to P position.

BCM outputs the unlock signal to all door lock actuators when it detects the shift position signal received from TCM via CAN communication is shifted from any position other than the P to P position.

Setting Change of Automatic Door Unlock Function

The unlock operation setting of the automatic door unlock function can be changed by combination meter setting.

REAR SEAT ALERT

It is a function to prevent mislay of luggage in the rear seat when getting off, by setting the function with the combination meter in advance when getting on.

Operation condition

When all of the following conditions are satisfied.

Setting	Condition
Alert only	Rear door: open → close Driver door: open → close Select "Alert only" of combination meter setting Vehicle: running → stop Shift position: P position
Alert & horn	Rear door: open → close Driver door: open → close Select "Alert & horn" of combination meter setting Vehicle: running → stop Shift position: P position Front door LH: 8 seconds after open → close the horn operates

TELEMATICS LOCK/UNLOCK FUNCTION

BCM outputs the lock signal to all door lock actuators when it detects the door lock signal received from TCU via CAN communication.
BCM outputs the unlock signal to driver/all door lock actuators (selective unlock function operation) when it detects the door unlock signal received from TCU via CAN communication.
