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 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 and power back door open*1 and panic*2 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).

    • Front door courtesy light switch assembly LH/RH

    • Rear door courtesy light switch assembly LH/RH

    • Back door courtesy 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 (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 door control receiver and signals from each ECU.

    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)*1

    Pressing the unlock switch twice within 5 seconds unlocks all doors after the driver door is unlocked.

    Automatic lock

    If none of the doors is opened within 30 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.

    Answer back (Wireless door lock buzzer)*2

    • 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.

    Panic alarm*1

    Pressing the panic switch of the electrical key transmitter sub-assembly for longer than approximately 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 map light assembly and No. 1 room light assembly switch in DOOR position).

    While the panic alarm is operating, pressing any switch of the electrical key transmitter sub-assembly cancels the alarm operation.

    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 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.
