id0914000092x2


Outline

•  When the door lock switch or the remote transmitter or the touch sensor located in outer handle is operated to lock/unlock, all the doors and the fuel-filler lid lock/unlock.
Note
•  The fuel-filler lid lock operation is delayed based on the personalized delay time.

Function


Door lock switch interlock function

•  When the door lock switch is operated to lock/unlock, all the doors and fuel-filler lid lock/unlock.
Note
•  The time until the fuel-filler lid is locked after locking the driver’s door can be changed.(Initial time is 0 sec)


Double locking function (With double locking)

•  When all the doors and liftgate are closed and locked two times concecutively, the unlock operation for all door lock knobs is disabled.


Collision detection unlock function

•  This function unlocks the doors in case of a collision to enhance rescue operation from outside the vehicle.


Auto door lock function

•  All doors and fuel-filler lid automatically lock/unlock in conjunction with the vehicle speed and the operation of the selector lever (ATX) and the ignition switch.


Function for locking all doors by lock knob operation without using remote transmitter

•  Any door can be locked without the remote transmitter or auxiliary key by setting the door lock knob to the lock position with the door open and closing the door.

Operation


Lock operation using door lock switch

1.  When the door-electrical supply unit (driver’s side) detects a door lock switch lock signal (1), it sends a door lock switch lock signal (2) using CAN communication to the body control module (BCM).

2.  When the body control module (BCM) receives a door lock switch lock signal (2), it determines the door lock operation and sends an all door lock signal (3) using CAN communication to the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) and electrical supply unit (ESU).

3.  When the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) and electrical supply unit (ESU) receive an all door lock signal (3), the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) turns the FET (lock side) on (4), and the electrical supply unit (ESU) turns the transistor on (4) and then the relay turns on (4).

4.  When the FET (lock side) turns on (4), the front and rear door latch and lock actuator motors perform a lock operation (5), and the front and rear doors lock. When the relay turns on, the fuel-filler lid lock actuator motor performs a lock operation, and the fuel-filler lid locks.

Note
•  The time until the fuel-filler lid is locked after locking the driver’s door can be changed.(Initial time is 0 sec)

Unlock operation using the door lock switch

1.  When the door-electrical supply unit (driver’s side) detects a door lock switch unlock signal (1), it sends a door lock switch unlock signal (2) using CAN communication to the body control module (BCM).

2.  When the body control module (BCM) receives a door lock switch unlock signal (2), it determines the door unlock operation and sends an all door unlock signal (3) using CAN communication to the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) and the electrical supply unit (ESU).

3.  When the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) and the electrical supply unit (ESU) receive an all door unlock signal (3), the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) turn the transistor on (4) and turn the door unlock relay on (4), at the same time FET (unlock side) on (4), and the electrical supply unit (ESU) turns the transistor on and then the relay turns on.

4.  When the door unlock relay (4) and FET (unlock side) turns on (4), the front and rear door latch and lock actuator motors perform an unlock operation (5), and the front and rear doors unlock. When the relay turns on, the fuel-filler lid lock actuator motor performs an unlock operation, and the fuel-filler lid unlock.

Double locking function (With double locking)

•  When all the doors and liftgate are closed and locked two times concecutively, the unlock operation for all door lock knobs is disabled.

1.  When the LOCK button of the remote transmitter is pressed, the remote transmitter sends a door lock signal to the keyless receiver (1).

2.  When the keyless receiver recveives a door lock signal, it sends a door lock signal to the LF control unit (2).

3.  When the LF control unit receives a door lock signal, it sends a door lock signal using SERIAL LFU (UART) to the body control module (BCM) (3).

4.  When the control module (BCM) receives a door lock signal, it sends a door lock signal (4) using CAN communication to the door-electrical spply unit (driver’s side), the door-electrical supply unit (passenger’s side) and the electrical supply unit (ESU).

5.  When the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) receive a door lock signal, they turn the FET on (5). And then the door latch and lock actuator motor performs a lock operation (6) and all the door lock.

6.  When the electrical supply unit (ESU) receives a door lock signal, it turns the transistor on (5) and turns the relay on. And then the fuel-filler lid actuator motor performs a lock operation (6) and the fuel-filler lid locks.

7.  When the LOCK button of the remote transmitter is pressed again (7) and send a door lock signal via keyless receiver (8) and the LF control unit (9) within approx. 3 sec after performing LOCK button operation, the body control module (BCM) determines the double locking and sends a double locking signal (10) to the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side).

8.  When the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) receive a double locking signal, they turn the FET and transistor (relay) on (11). And then the door latch and lock actuator motor performs a doubule locking operation (12), and the connection of all door knobs is disconnected. Therefore, the lock/unlock operation cannot be performed using the door lock knobs.

Collision detection unlock function operation

1.  When an air bag deploys, the SAS control module sends an air bag deployment signal (1) to the door-electrical supply unit(driver’s side) and the door-electrical supply unit(passenger’s side) as a CAN signal via the body control module (BCM).At the same time, the SAS control module sends an airbag deployment signal (1) to the door-electrical supply unit(driver’s side) and the door-electrical supply unit(passenger’s side) as a serial signal.

2.  The door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger’s side) receives the air bag deployment signal (1) and after approx. 6 sec, it operates (2) the front and rear door lock actuator motors, and the front and rear doors unlock.

Note
•  The time until the fuel-filler lid is locked by auto door lock operation cannot be changed.
Function for locking all doors by lock knob operation without using remote transmitter
•  All the doors, fuel filler lid, and the liftgate can be locked using the following procedure.
1.  Switch the ignition OFF (engine off).
2.  Open any of the doors and lock all the door lock knobs from unlock (lock stand-by status).
3.  Close any open door.
Caution
•  Even though the ignition is switched to a position other than OFF (engine off) between Steps 2 and 3 above, the lock stand-by status remains as is, and the doors are locked.
Remove the remote transmitter from the vehicle because unlocking by the remote transmitter left-in-vehicle prevention function does not occur.
