POWER DOOR LOCK CONTROL SYSTEM SYSTEM DESCRIPTION


  1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION


    1. The power door lock system locks/unlocks all doors.


      • The driver door control switch sends lock/unlock request signals to the main body ECU (multiplex network body ECU). Then, the main body ECU (multiplex network body ECU) sends these request signals to the door lock motors in each door to lock/unlock all doors at once in response to the inputs.

      • Operating the driver door lock using a mechanical key sends request signals to lock or unlock the doors to the main body ECU (multiplex network body ECU).

  2. FUNCTION OF MAIN COMPONENTS

    Component Function

    • Turns on when door is opened and turns off when door is closed.
    Front door lock assembly (for driver side)

    • Built-in motor locks or unlocks door.

    • Built-in door control switch (key-linked) detects door key operation status (locked or unlocked) and outputs a signal to main body ECU (multiplex network body ECU).

    • Built-in position switch detects door status (locked or unlocked) and outputs a signal to main body ECU (multiplex network body ECU). This switch turns off when door is locked and turns on when door is unlocked.

    Front door lock assembly (for front passenger side)

    Rear door lock assembly LH/RH

    • Built-in motor locks or unlocks door.

    • Built-in position switch detects door status (locked or unlocked) and outputs a signal to main body ECU (multiplex network body ECU). This switch turns off when door is locked and turns on when door is unlocked.
    Back door lock assembly

    • Built-in motor opens door latch.

    • Performs back door open operation according to locked/unlocked state determination of main body ECU (multiplex network body ECU).

  3. SYSTEM FUNCTION


    1. This system is controlled by the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) outputs signals to each door lock motor. The power door lock control system has the following functions:

      Function Outline
      Manual lock and unlock function This function can lock or unlock all doors by the door control switch operation.
      Key-linked lock and unlock function This function, which is linked with the mechanical key cylinder, can lock or unlock all doors when a lock or unlock operation is effected.
      Manual unlock prohibition function

      When the condition below is met, unlocking the vehicle using the door control switch will be prohibited.


      • The doors are locked using a mechanical key, door control transmitter or entry lock operation with all doors closed.
      Key lock-in prevention function When the key is in the vehicle, performing the door lock operation will not lock the door.
      Double locking function*1

      • The double locking function also prevents the doors from being opened through the operation of the inside door knobs. Thus, the doors cannot be opened either from inside or outside the vehicle.

      • To lock the doors with this function, pressing the transmitter lock switch twice within 5 seconds or touching lock sensor on the outside door handle twice with holding the key within 5 seconds activates the double locking function. However, as an emergency unlocking maneuver, only the driver door can be unlocked with a key.

      Note

      Never activate the double locking function when there are people in the vehicle because the doors cannot be opened from the inside. If the doors are locked by accident, unlock the door by using the wireless unlock operation or entry unlock operation.
