Operation
Lock/unlock operation using door lock switch
1. When the door-electrical supply unit (driver’s side) detects a door lock switch signal (lock/unlock) (1), it sends the door lock switch signal (lock/unlock) (2) to the body control module (BCM) via CAN communication.
2. When the body control module (BCM) receives the door lock switch signal (lock/unlock) (2), it determines that the doors are to be locked/unlocked and sends a lock/unlock request signal (3) to the following parts via CAN
-
• Door-electrical supply unit (driver's side)
• Door-electrical supply unit (passenger’s side)
• Electrical supply unit (ESU)
• Charging port electrical supply unit
3. When the door-electrical supply unit (driver's side) and the door-electrical supply unit (passenger’s side) receive the lock/unlock request signal (3), they operate (4) the motors of the door lock actuators to lock/unlock the doors.
4. When the electrical supply unit (ESU) receives the lock/unlock request signal (3), it operates (4) the motor of the liftgate latch and lock actuator to lock/unlock the liftgate.
5. When the charging port electrical supply unit receives the lock/unlock request signal (3), it operates (4) the motor of the charge lid lock actuator to lock/unlock the charging port lid.
Double locking function (With double locking)
1. When the following operation condition is met, the body control module (BCM) sends a double-locking request signal (2) to the door-electrical supply units (driver's side and passenger's side).
-
Operation condition
-
• The lock button on the remote transmitter is pressed again (1) within approx. 3 s after locking all the doors and the liftgate using the remote transmitter.
2. When the door-electrical supply units (driver's side and passenger's side) receive the double-locking request signal, the motors of the door lock actuators operate (3) the double-locking function.
3. When the door lock actuator operates the double-locking function, the following operations cannot be performed.
-
• Unlocking doors using door lock knob
• Opening doors using inner handle
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
-
• When the collision detection unlock function operates, power is assured from the backup power supply.
Auto Door Lock Operation
Selector lever interlock door lock/unlock control
• The doors and charge lid lock when the selector lever is shifted to a position other than the P position with all the following conditions met.
-
― Main power ON (READY 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
• The doors and charge lid unlock when the selector lever is shifted to the P position with all the following conditions met.
-
― Main power ON (READY on) is detected
― AUTO P control is operating
Vehicle speed interlock door lock control
• The doors and charge lid unlock when a vehicle speed of 20 km/h {12 mph} or more is detected with all the following conditions met.
-
― Main power ON (READY on) is detected
― All door latch switch OFF (all doors closed condition) is detected
― Liftgate latch switch OFF (liftgate closed condition) is detected
IG interlock door unlock control
• When all of the following conditions are met, the doors unlock when it is detected that the main power is switched from ON (READY off or on) to OFF or ACC.
-
― Doors locked by selector lever interlock door lock control or vehicle interlock door lock control
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. Main power is switched 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 main power is switched to a position other than 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.
