System Description

WIRELESS DOOR LOCK CONTROL SYSTEM
The wireless door lock control system can be used to lock and unlock all doors (including the back door) 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 (ECU aggregation box 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 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 (ECU aggregation box 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 (instrument panel junction block assembly).
Front door lock assembly LH/RH Back door lock assembly	The built-in motor locks or unlocks the door. Transmits the door lock position of each door to the main body ECU (instrument panel junction block assembly).
Rear door lock assembly LH/RH	The built-in motor locks or unlocks the door.
Certification ECU (ECU aggregation box assembly)	Matches the code data with the registered code and outputs the code data to the main body ECU (instrument panel junction block assembly).

SYSTEM FUNCTION

The electrical key transmitter sub-assembly has the lock, unlock and panic switches. Operating these switches activate 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 .

Function	Operation
All door lock	Pressing the lock switch locks all doors (including the back door).
All door unlock (Unlock 2 operation)	Pressing the unlock switch twice within 5 seconds unlocks all doors (including the back door) after the driver door is unlocked.
Automatic lock	If none of the doors is opened within 60 seconds after they are unlocked by the wireless door lock control, all doors (including the back door) 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 back 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 more than about 1.5 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 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 (including the back door) are closed or the unlock switch is pressed.
Illuminated entry	When all doors (including the back door) 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 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.
