WIRELESS DOOR LOCK CONTROL SYSTEM


  1. FUNCTION OF MAIN COMPONENTS


    1. The main components in the wireless door lock control system have the following functions:

      Component Outline
      Main Body ECU (Multiplex Network Body ECU) Drives all door lock motors in response to signals.
      Door Lock Assembly Door Lock Position Switch Detects whether the door is locked or unlocked and sends this information to the main body ECU (multiplex network body ECU).
      Door Lock Motor Drives the motor in response to signals from the main body ECU (multiplex network body ECU) and locks or unlocks the doors.
      Door Courtesy Light Switch Assembly Detects whether the doors are open or closed and sends this information to the main body ECU (multiplex network body ECU).
      Back Door Motor Unit*1 Power Back Door ECU (Multiplex Network Door ECU)

      • Drives the back door lock motor according to back door open signals from the main body ECU (multiplex network body ECU).

      • Controls the power back door system.
      Multiplex Network Door ECU*2 Drives the back door lock motor according to back door open signals from the main body ECU (multiplex network body ECU).
      Back Door Lock Assembly

      • Detects whether the back door is open or closed and sends this information to the main body ECU (multiplex network body ECU).

      • Drives the motor in response to signals from the main body ECU (multiplex network body ECU) and releases the back door latch.
      Electrical Key Transmitter Sub-assembly Sends the ID code and function code to the door control receiver.
      Door Control Receiver Receives a lock or unlock signal from the transmitter and sends this information to certification ECU (smart key ECU assembly).
      Certification ECU (Smart Key ECU Assembly) Sends a lock or Unlock signal to the main body ECU (multiplex network body ECU).
      Combination Meter Assembly Receiving the main body ECU (multiplex network body ECU) signals causes to blink the hazard light as an answer back.
      Wireless Door Lock Buzzer Sounds as an answer back according to the signal from the main body ECU (multiplex network body ECU).

  2. FUNCTION


    1. The wireless door lock control system has the following functions:

      Function Outline
      ALL Doors Lock Pressing the lock switch of the electrical key transmitter sub-assembly locks all doors.
      ALL Doors Unlock Pressing the unlock switch of the electrical key transmitter sub-assembly unlocks all doors.
      Power Back Door Open or Close*1 Pressing the power back door button for approx. 1 second opens and closes the power back door.
      Slide Door Open Pressing the power slide door switch of the electrical key transmitter sub-assembly for longer than approximately 0.8 seconds opens the slide door.
      Slide Door Close Pressing the power slide door switch of the electrical key transmitter sub-assembly for longer than approximately 0.8 seconds closes the slide door.
      Scheduled Lock Function With this function, when doors other than the power slide door are closed and the lock switch is pressed while the power slide door is closing, door lock is performed at that moment and door lock is completed when the slide door is finished closing.
      With this function, when doors other than the power back door are closed and the lock switch is pressed while the power back door is closing, door lock is performed at that moment and door lock is completed when the back door is finished closing.*1
      Door Ajar Warning*2 If any door is open or ajar, pressing the lock switch of the electrical key transmitter sub-assembly will cause the wireless door lock buzzer to sound for about 5 seconds as a warning.
      Answer Back

      • When the doors are being locked or unlocked using the door control transmitter sub-assembly, the wireless door lock buzzer sounds*3 and the hazard warning lights blink once while locking and twice while unlocking.

      • When the power back door is opened and closed by using the electrical key transmitter sub-assembly, the hazard warning lights blink twice as an answer back.
      Automatic Relock If none of the doors are opened within 30 seconds after they are unlocked using wireless door lock control, all the doors will be locked again automatically.
      Illuminated Entry When all the doors are locked, pressing the unlock switch causes the interior lights to illuminate simultaneously with the unlock operation.
      Key Code Registration This function enables registration of additional key codes for the certification ECU (smart key ECU assembly).
