WIRELESS DOOR LOCK CONTROL SYSTEM(w/ 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 engages the door lock control.

  2. FUNCTION OF MAIN COMPONENTS

    Component Function
    Electrical key transmitter sub-assembly

    • Has lock, unlock, luggage open and panic* switches.

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

    • Illuminates 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).

    • Front door courtesy light switch LH/RH

    • Luggage door courtesy light switch

    • 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 (network gateway ECU).

    • Front door lock assembly LH/RH

    • Built-in motor locks or unlocks door.

    • Transmits the door lock position of each door to the main body ECU (network gateway ECU).
    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.

  3. SYSTEM FUNCTION

    The electrical key transmitter sub-assembly has the lock and unlock switches. Operating these switches activates each function. The wireless door lock control system has the following functions:

    Tech Tips

    The default settings of the following functions are on. Part of these functions can be customized Click here.

    Function Operation
    All door lock function Pressing the lock switch locks all doors.
    All door unlock function*1 Pressing the unlock switch unlocks all doors.
    All door unlock function (Unlock 2 operation)*2 Pressing the unlock switch twice within 5 seconds unlocks all the doors after the driver door is unlocked.
    Luggage compartment door open Pressing the luggage open switch of the electrical key transmitter sub-assembly for longer than about 0.8 seconds opens the luggage compartment door.
    Answer back function (Hazard warning light) Hazard warning lights flash once when doors are locked, and flash twice when doors are unlocked to indicate that the request has been completed.
    Answer-back function (Wireless door lock buzzer)*3 Wireless door lock buzzer sound once when doors are locked, and sound twice when doors are unlocked to indicate that the request has been completed.
    Panic alarm function*2

    Pressing the panic switch of the electrical key transmitter sub-assembly for longer than about 0.8 seconds causes the following alarms to activate:


    • Sound the vehicle horns.

    • Blinks the headlights, hazard warning lights and taillights.

    • Illuminates the interior lights (when the interior light door switch on).

    While the panic alarm is operating, pressing any switch of the electrical key transmitter sub-assembly cancels the alarm operation.
    Vehicle Position Sensing Function*4 The vehicle position sensing function is a function that sounds the vehicle horn and flashes the hazard warning lights by operating the transmitter in order to indicate the vehicle's position to the user.
    Door ajar warning function The buzzer sounds when the lock switch is pressed when any of the doors are ajar, and it sounds for 10 seconds continuously. The buzzer stops when all doors are closed or the unlock switch is pressed.
    Automatic locking function 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.
    Illuminated entry function When all doors are locked, pressing the UNLOCK switch causes the interior lights to come on simultaneously with the unlock operation.
    Self-diagnostic function

    The system enters self-diagnostic mode under the following conditions.


    • If the door control receiver receives normal radio waves from the electrical key transmitter sub-assembly when the system is in diagnostic mode, it flashes the interior light in a normal pattern that corresponds to the function of each switch.
    Transmitter recognition code registration function Enables 4 modes for registering (writing and storing) transmitter recognition codes in EEPROM, built into door control receiver.
