System Description [03/2017 - ]

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.

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.

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:

HINT:

The default settings of the following functions are on. Part of these functions can be customized (Refer to CUSTOMIZE PARAMETERS [03/2017 - ] ).

Function	Operation
All door lock function	Pressing the lock switch locks all doors.
All door unlock function (Unlock 2 operation)	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)	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	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	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.
Transmitter recognition code registration function	Enables 4 modes for registering (writing and storing) transmitter recognition codes in EEPROM, built into door control receiver.
