WIRELESS DOOR LOCK CONTROL 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 electrical key and TPMS receiver assembly. 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 multi channel 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 electrical key and TPMS receiver assembly.

  3. FUNCTION OF MAIN COMPONENTS

    Component Function
    Electrical key transmitter sub-assembly

    • Has the lock, unlock and luggage door open.

    • Transmits weak radio waves (recognition codes and function codes) to the electrical key and TPMS receiver assembly.

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

    • Front door courtesy light switch assembly LH/RH

    • Rear door courtesy light switch assembly LH/RH

    • Luggage compartment door courtesy light switch assembly

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

    • Outputs door status signals (open or closed) to the main body ECU (multiplex network body ECU).

    • Front door lock assembly LH/RH

    • Rear door lock assembly LH/RH

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

    • Transmits the door lock position of each door to the main body ECU (multiplex network body ECU).
    Certification ECU (Smart key ECU assembly) Sends wireless door lock control signals in response to the code data from the electrical key and TPMS receiver assembly and signals from each ECU.

  4. SYSTEM FUNCTION

    The electrical key transmitter sub-assembly has lock, unlock, luggage door open and panic 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.

    All door unlock

    (Unlock 2 operation)

    		 Pressing the unlock switch twice within 5 seconds unlocks all doors after the driver door is unlocked.
    Luggage compartment door open Pressing the luggage door open switch of the electrical key transmitter sub-assembly for longer than about 0.8 seconds opens the luggage door.
    Automatic lock If none of the doors is opened within 60 seconds after they are unlocked by the wireless door lock control, all doors will lock again automatically.
    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.
    Door ajar warning The buzzer sounds when the lock switch is pressed when any of the doors are ajar, and it sounds for 5 seconds continuously. The buzzer stops 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 electrical key and TPMS receiver assembly 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.
