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 engages the door lock control.
2. 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.
3. FUNCTION OF MAIN COMPONENTS
Component |
Function |
---|---|
Electrical key transmitter sub-assembly |
|
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). |

|
|
|
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. |
4. SYSTEM FUNCTION
The electrical key transmitter sub-assembly has the lock, unlock, and panic 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 (See page ).
Function |
Operation |
---|---|
All door lock |
Pressing the lock switch locks all doors. |
All door unlock (Unlock 2 operation) |
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 60 seconds after they are unlocked by the wireless door lock control, all doors will lock again automatically. |
Answer back (Hazard warning light) |
|
Answer back (Wireless door lock buzzer) |
|
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:
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 |
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. |
