System Description [08/2019 - 08/2022]

WIRELESS DOOR LOCK CONTROL SYSTEM
The wireless door lock control system functions to lock and unlock all the doors from a distance. The system is controlled by a door control transmitter assembly which sends radio waves to the door control and tire pressure monitoring system receiver assembly. The main body ECU (multiplex network body ECU) performs an ID code identification process and engages 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 is pressed, the channel is switched alternately between 2 different frequencies and the signal is sent to the door control and tire pressure monitoring system receiver assembly.

FUNCTION OF MAIN COMPONENTS

Component	Function
Door control transmitter assembly	Has lock, unlock open and panic switches. Transmits weak radio waves (recognition codes and function codes) to the door control and tire pressure monitoring system receiver assembly. Illuminates the indicator light (LED) during transmission.
Door control and tire pressure monitoring system receiver assembly	Receives weak radio waves from the door control transmitter assembly and sends them to the main body ECU (multiplex network body ECU).
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).
Un-lock warning switch assembly	Detects if the key is inserted in the ignition key cylinder or not.
Front door lock assembly LH/RH Rear door lock assembly LH/RH Back door lock assembly	Built in motor locks or unlocks door. Transmits the door lock position of each door to the main body ECU (multiplex network body ECU)
Main body ECU (multiplex network body ECU)	Sends wireless door lock control signals in response to the code data from the door control and tire pressure monitoring system receiver assembly and signals from each switch.

Automatic lock	If none of the doors is opened within 60 seconds after they are unlocked by wireless door lock control, all the 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.
Panic alarm	Pressing the panic switch of the door control transmitter 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. While the panic alarm is operating, pressing any switch of the door control transmitter 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 the doors are locked, pressing the unlock switch causes the interior lights to come on simultaneously with the unlock operation.
Self-diagnostic mode	The following are conditions to enter self-diagnostic mode: If the door control and tire pressure monitoring system receiver assembly receives normal radio waves from the door control transmitter assembly when the system is in diagnostic mode, it flashes the interior lights and sounds the wireless door lock buzzer in a normal pattern that corresponds to the function of each switch.
