Power Locks: Description and Operation

CENTRAL DOOR LOCKING SYSTEM
The central door locking system operates the door lock actuator to lock or unlock the doors and liftgate using the operation of the door lock switch or key built into the driver's side inside door lock knob and front power window (main or sub) switch. The system has the following operations and features.
- Insert the key into the driver's key cylinder and turn once to the unlock side to unlock the driver's door. Turn the key once again to the unlock side to unlock all doors.
- All doors can be locked or unlocked using the front door [RH] key cylinder key operation.
- All doors and liftgate can be locked using the driver's inside door lock knob.
- All doors can be locked using the door lock switch built into the front power window (main or sub [RH]) switch.
- A key reminder function that automatically unlocks all doors when door lock operation is performed and the front doors are opened while the key is inserted into the ignition switch is provided.

CENTRAL DOOR LOCKING SYSTEM OPERATION
When the driver's inside lock knob is locked or unlocked, the lock relay inside the ETACS-ECU turns on to lock or unlock all doors.

With all the doors locked, turning the key in the driver's door unlocks the door. Turning it again makes the door unlock relay close to send a signal for unlocking all doors.

When the door lock switch (built into the power window switch) is operated, the lock or unlock relay inside the ETACS-ECU is turned on to lock or unlock all doors.







The ECUs affect the functions and control of the central door locking system.


DOOR LOCK FUNCTION







OPERATING THE DRIVER'S OR FRONT PASSENGER'S DOOR LOCK KEY CYLINDER
When you insert the ignition key to the driver's or front passenger's door lock key cylinder and turn the key clockwise to lock the door, the ETACS-ECU energizes its door lock relay for 0.25 second to activate all the door lock actuators. Then all the doors will be locked.







OPERATING THE DRIVER'S OR FRONT PASSENGER'S DOOR LOCK SWITCH
When the door is locked by driver's or front passenger's door lock switch, the ETACS-ECU energizes its door lock relay for 0.25 second to activate all the door lock actuators. Then all the doors will be locked.

DOOR UNLOCK FUNCTION







OPERATING THE DRIVER'S DOOR LOCK KEY CYLINDER
When you insert the ignition key to the driver's door lock key cylinder and turn the key counterclockwise to unlock the door, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate only the driver's door lock actuator. Then only the driver's door will be unlocked. When you turn the key counterclockwise again, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate all the door lock actuators. Then all the doors will be unlocked.







OPERATING THE FRONT PASSENGER'S DOOR LOCK KEY CYLINDER
When you insert the ignition key to the front passenger's door lock key cylinder and turn the key counterclockwise to unlock the door, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate all the door lock actuators. Then all the doors will be unlocked.







OPERATING THE DRIVER'S OR FRONT PASSENGER'S DOOR LOCK SWITCH
When the door is unlocked by driver's or front passenger's door lock switch, the ETACS-ECU energizes its door unlock relay for 0.25 second to activate all the door lock actuators. Then all the doors will be unlocked.
