POWER DOOR AND FUEL-FILLER LID LOCK SYSTEM

id091400705400

Outline

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.

Collision detection unlock function

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

Note

•  Depending on the impact location, the sensor may not detect and the collision detection unlock function may not operate. For details, refer to [AIR BAG SYSTEM]. (See AIR BAG SYSTEM [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

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 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.

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.

Collision detection unlock function operation

1.  When the air bags deploy, the SAS control module sends an air bag deployment signal to the door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger's side) via CAN signals and electric signals.

2.  The door-electrical supply unit (driver’s side) and the door-electrical supply unit (passenger's side) receive the air bag deployment signal and after approx. 6 s, they operate the front door lock actuator motors, and the front doors unlock.

Note

•  For the deployment conditions of each air bag, refer to [AIR BAG SYSTEM]. (See AIR BAG SYSTEM [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

•  When the collision detection unlock function operates, power is assured from the backup power supply.

Auto Door Lock Operation

―  Ignition switch ON (engine on) is detected

―  All door latch switch OFF (all doors closed condition) is detected

―  Liftgate latch switch OFF (liftgate closed condition) is detected

―  Vehicle is determined to be driven

―  Ignition switch ON (engine off or on) is detected

―  Ignition switch ON (engine on) is detected

―  All door latch switch OFF (all doors closed condition) is detected

―  Liftgate latch switch OFF (liftgate closed condition) is detected

―  Doors locked by selector lever interlock door lock control or vehicle interlock door lock control

Note

•  The time until the fuel-filler lid is locked by auto door lock operation cannot be changed.

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.
