System Description [09/2014 - ]

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.
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 door control receiver.

FUNCTION OF MAIN COMPONENTS

Component	Function
Electrical key transmitter sub-assembly	Has the lock, unlock, luggage open and panic 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 Luggage compartment 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 with motor 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.

SYSTEM FUNCTION

The electrical key transmitter sub-assembly has lock and unlock switches. Operating these switches activates each function.

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 compartment 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.
Answer-back (Wireless door lock buzzer)	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. When the luggage compartment door is opened by wireless operation, the wireless door lock buzzer sounds.
Panic alarm	Pressing the panic switch of the electrical key transmitter sub-assembly for longer than about 0.8 seconds causes the following alarms to activate: Sounds the vehicle horns and security horn. Blinks the Headlights, hazard warning lights and taillights. Illuminates the interior lights. 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 for 5 seconds continuously when the lock switch is pressed when any of the doors are ajar. 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.
