SYSTEM DESCRIPTION
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 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 operates the door lock control.
FUNCTION OF MAIN COMPONENTS
Component |
Function |
---|---|
Door control transmitter assembly |
|
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). |
|
|
Unlock warning switch assembly |
Detects if the key is inserted in the ignition key cylinder or not. |
Front door lock with motor assembly Rear door lock with motor assembly |
|
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. |
SYSTEM FUNCTION
The door control transmitter 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.

Function |
Operation |
---|---|
All door lock |
Pressing the lock switch locks all doors. |
All door unlock |
Pressing the unlock switch unlocks all of the doors. |
All door unlock (Unlock 2 operation) |
Pressing the unlock switch twice within 5 seconds unlocks all of the doors after the driver door is unlocked. |
Automatic lock |
If none of the doors is opened within 60 seconds after they are unlocked by wireless door lock control, all doors will lock again automatically. |
Answer-back (Hazard warning light) |
|
Answer-back (Wireless door lock buzzer) *1 |
|
Panic alarm*1 |
Pressing the panic switch of the door control transmitter 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 door control transmitter assembly cancels the alarm operation. |
Door ajar warning*1, *2 |
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. |
Wireless reservation lock*1, *2 |
Pressing the lock button of the door control transmitter assembly while the door is open causes the door to lock when it is closed. |
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 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 in a normal pattern that corresponds to the function of each switch. |
Transmitter recognition code registration |
Enables registration (writing and storing) of door control transmitter assembly recognition codes in the EEPROM that is contained in the door control and tire pressure monitoring system receiver assembly. |
HINT:
*2: If the customize setting "Wireless Lock Function with Doors Open" is set to ON, "Open Door Warning" will no longer operate. If "Open Door Warning" is set to ON, "Wireless Lock Function with Doors Open" will no longer operate. If both settings are set to ON, "Wireless Lock Function with Doors Open" will be given priority.
TRANSMITTER RECOGNITION CODE REGISTRATION FUNCTION
The table below shows the 4 ID registration function modes. The codes are electronically registered (written and stored) in the EEPROM that is contained in the door control and tire pressure monitoring system receiver assembly.
Mode |
Function |
---|---|
Add mode |
Adds a newly received code while preserving any previously registered codes. This mode is used when adding a new door control transmitter assembly. If the maximum registration number is exceeded, the oldest one is cleared first. |
Rewrite mode |
Clears all previously registered codes and registers only newly input codes. |
Confirmation mode |
Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist. |
Prohibition mode |
Deletes all registered codes and disables the wireless door lock function. This mode is used when the door control transmitter assembly is lost. |
CONDITIONS THAT WIRELESS FUNCTIONS DO NOT OPERATE
(a) The lock function will not operate when either of the following conditions is met:
(b) The unlock function will not operate when the following condition is met:
