WIRELESS DOOR LOCK CONTROL SYSTEM(w/ Smart Entry and Start System) SYSTEM DESCRIPTION


  1. WIRELESS DOOR LOCK CONTROL SYSTEM

    The wireless door lock control system can be used to lock and unlock all doors from a distance. The system is controlled by an electrical key transmitter sub-assembly which sends radio waves to the door control receiver. The certification ECU (smart key ECU assembly) performs an ID code identification process and operates the door lock control.

  2. MULTI CHANNEL FUNCTION

    The wireless door lock control system has a multichannel function. Each time the switch on the electrical key transmitter sub-assembly is pressed, the channel is switched alternately between 2 different frequencies and the signal is sent to the door control receiver.

  3. FUNCTION OF MAIN COMPONENTS

    Component Function
    Electrical key transmitter sub-assembly

    • Has the lock, unlock, back door open*1 and alarm*4 switches.

    • Transmits weak radio waves (recognition codes and function codes) to the door control receiver.

    • Illuminates the indicator light (LED) during transmission.
    Door control receiver Receives weak radio waves from the electrical key transmitter sub-assembly and sends them to the certification ECU (smart key ECU assembly).

    • Placed on each door.

    • Detects the door status (open or closed) and outputs data to the body ECU.

    • Turns on when a door is opened and turns off when it is closed.

    • The built-in motor locks or unlocks the door.

    • The built-in unlock detection switch detects the door status (locked or unlocked) and outputs a signal to the certification ECU (smart key ECU assembly) and body ECU. This switch turns off when the door is locked and turns on when the door is unlocked.
    Certification ECU (Smart key ECU assembly) Sends wireless door lock control signals in response to the code data from the door control receiver and signals from each ECU.

  4. SYSTEM FUNCTION

    The electrical key transmitter sub-assembly has the lock, unlock, back door open* and alarm switches. Operating these switches activates each function.

    The wireless door lock control system has the following functions:

    Function Operation
    All door lock Pressing the lock switch locks all doors.
    All door unlock Pressing the unlock switch unlocks all doors.
    Automatic lock If none of the doors are opened within 30 seconds after they are unlocked by the wireless door lock control, all doors will lock again automatically.
    Power back door open/close*1 Pressing the back door open switch of the electrical key transmitter sub-assembly for longer than about 0.8 seconds opens or closes the back door.
    Remote alarm function*2

    Pressing the alarm switch of the transmitter for more than approximately 0.8 seconds causes the following alarms to activate:


    • Sounds the horns.

    • Flashes the hazard warning lights, and side turn signal lights.
    Answer back (Hazard warning light)

    • When the doors are locked by wireless operation, the hazard warning lights flash once.

    • When the doors are unlocked by wireless operation, the hazard warning lights flash twice.
    Answer back (Wireless door lock buzzer)*3

    • When the doors are locked by wireless operation, the wireless door lock buzzer sounds once.

    • When the doors are unlocked by wireless operation, the wireless door lock buzzer sounds twice.
    Door ajar warning The wireless door lock buzzer sounds when the lock switch is pressed when any of the doors are ajar, and it sounds for 5 seconds continuously. The wireless door lock buzzer stops sounding when all doors are closed or the unlock switch is pressed.
    Illuminated entry When all doors are locked, pressing the unlock switch causes the interior lights to come on simultaneously with the unlock operation.
    Self-diagnostic mode If the door control receiver receives normal radio waves from the electrical key transmitter sub-assembly when the system is in diagnostic mode, it sounds the wireless door lock buzzer in a normal pattern that corresponds to the function of each switch.
