System Outline

In the door lock system, the respective door ECU controls the door lock motor. When the doors are locked/unlocked by the door lock control SW or the door key lock/unlock SW, the respective door ECU controls the motors through multiplex communication.

1. Auto Lock Function 

   In case all the doors are closed with the ignition SW at ON, all the doors will be locked when the following conditions are met:

   * Shift lever is moved from P position to other positions.

   * Any door is unlocked

2. Door Closer System (w/Door Closer) 

When the front and rear door closer system detects that the front and rear doors are ajar, it automatically actuates the motors to fully close the front and rear doors.

Position detection switches are enclosed in the door closer mechanism in each of the front and rear doors lock assemblies to detect whether the front and rear doors are open, closed, or ajar. If a detection signal that indicates that a front and rear doors are ajar is transmitted to the door ECU, the door ECU actuates the operation of the door closer motor in order to fully close the front and rear doors.

In this system, each door is independently controlled by the door ECU that is provided in the respective door. The door ECUs, which maintain communication via the BEAN (Body electronics area network), belong the door bus.

In this system, the door lock control receiver receives weak radio wave transmitted from the transmitter built-into the ignition key and outputs the signal to the theft deterrent ECU. Through communication control of the theft deterrent ECU and door ECU etc., all the doors and the luggage door can be locked and unlocked by the remote control.

1. Normal Operation 

   * Lock operation

   When the lock SW on the transmitter is pressed, all the doors are locked.

   * Unlock operation

   When the unlock SW on the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressed again within 3 sec., all the doors are unlocked.

   * Luggage door unlock operation

   When the luggage door unlock SW is kept pressed for approximately 1.0 sec. or longer, the luggage door is opened.

2. Auto Lock Function 

   If the door is not actually opened within 30 sec. after the door has been unlocked by pressing the unlock SW on the transmitter, all the doors are automatically locked. If any of the following conditions is detected, the auto lock does not function.

   Any door is opened.

   The ignition key is inserted into the ignition SW.

   When the lock detection SW of all the doors are locked.

3. Wireless Door Lock Stop Function 

   If any of the following conditions is detected, the wireless door lock does not function.

   * Lock operation

   Any door is open (The door courtesy SW is on).

   The ignition key is inserted into the ignition key cylinder (The unlock warning SW is on).

   The ignition SW is turned to the ON position.

   * Unlock operation

   The ignition SW is turned to ON position.

   * Luggage door unlock operation

   The ignition SW is turned to ON position.

4. Anser Back Function 

   * When the doors are locked by wireless operation, the buzzer sounds once and the hazard lights blink once.

   * When the doors are unlocked by wireless operation, the buzzer sounds twice and hazard lights blink twice.

   * When the luggage door is unlocked by wireless operation, the buzzer sounds once.

   * When the doors are locked by wireless operation with each door open (Courtesy SW ON), the buzzer sounds. If all the doors are closed, doors are unlocked by wireless operation or buzzer keeps sounding for 10 seconds, the buzzer sounding stops.

5. Illuminated Entry Function 

   If the doors are unlocked when all the doors are locked, the room light is turned on.

6. Panic Mode Function 

   When the lock switch on the transmitter is kept pressed for approximately 2.5 sec., the theft deterrent ECU receives the signal and enters the panic mode. The theft alarm goes on upon receiving the signal, the theft deterrent ECU, and the headlights and taillights flash through the communication of the theft deterrent ECU and door ECU etc. At this time, when any SW on the transmitter is pressed, the panic mode is cancelled, the theft alarm is stopped, and the headlights and taillights go off.

7. Repeat Function 

   If the lock detection signal in response to the output signal is not received after theft deterrent ECU has output the lock signal, the lock signal is output again after approximately 1 sec.
