System Description

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 hand-held transmitter which sends radio waves to the door control receiver. The main body ECU performs an ID code identification process and engages the door lock control.

FUNCTION OF MAIN COMPONENTS

Component	Function
Door control transmitter	Has 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 (recognition codes and function codes) and outputs them as code data to the main body ECU.
Front door courtesy light switch Rear door courtesy light switch Luggage compartment door courtesy light switch	Turns on when a door is opened and turns off when it is closed. Outputs door status codes (open or closed) to the main body ECU.
Unlock warning switch	Detects if the key is inserted in the ignition key cylinder or not.
Door lock position switch	Transmits the door lock positions of each door to the main body ECU.
Wireless door lock buzzer	Emits beep (answer back) when doors are locked or unlocked, or luggage compartment door is opened by wireless operation.
Main body ECU	Sends wireless door lock control signals in response to the code data from the door control receiver and signals from each switch.

SYSTEM FUNCTION

The door control transmitter has the LOCK, UNLOCK, LUGGAGE OPEN, 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. Refer to CUSTOMIZE PARAMETERS .

Function	Operation
All door lock	Pressing the LOCK switch locks all doors.
All door unlock (2-step unlock)	Pressing the UNLOCK switch twice within 3 seconds unlocks all the doors after the driver's door is unlocked.
Automatic lock	If none of the doors is opened within 601 or 302 seconds after they are unlocked by the wireless door lock control, all the doors will lock again automatically.
Panic alarm	Pressing the PANIC switch of the transmitter for longer than about 0.8 seconds causes the following alarms to activate: Sounds the horn and security horn. Flashes the hazard lights, headlights, and taillights. Illuminates the front interior light (when the switch is in the DOOR position). While the panic alarm is operating, pressing any switch of the transmitter cancels the alarm operation.
Luggage compartment door opener	Pressing the LUGGAGE OPEN switch of the transmitter opens the luggage compartment door.
Answer back	When the doors are locked by wireless operation, the wireless door lock buzzer sounds once and the hazard warning lights flash once. When the doors are unlocked by wireless operation, the wireless door lock buzzer sounds twice and the hazard warning lights flash twice. When the luggage compartment door is opened by wireless operation, the wireless door lock buzzer sounds once.
Door ajar warning	The buzzer sounds when LOCK is pressed when any of the doors are ajar. When all the doors are closed or when UNLOCK is pressed, the buzzer will stop after it sounds for 10 seconds continuously.
Illuminated entry	When all the doors are locked, pressing UNLOCK causes the interior lights to come on simultaneously with the unlock operation.
Self-diagnostic mode	The following are ways to enter the self-diagnostic mode: If the door control receiver receives normal radio waves from the door control transmitter when the system is in diagnostic mode, it sounds the wireless door lock buzzer and flashes the interior light in a normal pattern that corresponds to the function of each switch. Read DTCs with Techstream.
Transmitter recognition code registration	Enables the registration (writing and storing) of 6 types of transmitter recognition codes in the EEPROM that is contained in the door control receiver.

*1: except for Korea
*2: for Korea

TRANSMITTER RECOGNITION CODE REGISTRATION FUNCTION

The table below shows the 6 ID registration function modes by which up to 6 different codes can be registered. The codes are electronically registered (written and stored) in the EEPROM that is contained in the door control receiver.

Mode	Function
Add mode	Adds a newly received code while preserving any previously registered codes. This mode is used when adding a new transmitter. If the number of registered codes exceeds 6, the oldest registered code is erased first.
Rewrite mode	Erases 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 the registered codes and disables the wireless door lock function. This mode is used when the transmitter is lost.

CONDITIONS THAT WIRELESS FUNCTIONS DO NOT OPERATE
1. Lock operation is not available when:
  - Any of the doors is open.
  - The key is inserted in the ignition key cylinder.
2. Unlock operation is not available when:
  - The key is inserted in the ignition key cylinder.
3. Luggage compartment door opener is not available when:
  - The key is inserted in the ignition key cylinder.
