System Outline

Door lock control (Lock and unlock) and panic control is performed by remote control, using low-power electrical waves emitted by a transmitter, without the ignition key needing to be inserted in the door key cylinder.

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 seconds, all the doors are unlocked.

2. Auto Lock Function 

   When the door lock is not actually opened within 30 seconds after the door has been unlocked by the unlock SW on the transmitter, all the doors will be automatically locked. If any of the following conditions are detected, the wireless door 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 reads locked.

3. Wireless Door Lock Stop Function 

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

   Lock operation

   * When any door is open (Door courtesy SW on)

   * The ignition key is inserted into the ignition SW (Unlock warning SW on)

   * Ignition SW is ON (IG)

   Unlock operation

   * Ignition SW is ON (IG)

4. Buzzer Sound Function 

   During the lock operation, when the main body ECU receives a lock signal from the door lock detection SW, the wireless door lock buzzer sounds once. During the unlock operation, when the main body ECU receives an unlock signal from the door lock detection SW, the wireless door lock buzzer sounds twice.

   If any of the doors is open when the main body ECU receives a lock signal from the transmitter, the wireless door lock buzzer sounds continuously for approximately 10 seconds. If the door is closed, or ignition SW is turned on, or if an unlock signal is received from the transmitter while the buzzer is sounding, the buzzer stops.

5. Visual Confirmation of Lock or Unlock 

   During the lock operation, when the main body ECU receives a lock signal from the door lock detection SW, the turn signal lights are flashed once. During the unlock operation, when the main body ECU receives an unlock signal from the door lock detection SW, the turn signal lights are flashed twice.

6. Repeat Function 

   If the lock detection signal that is sent in response to the output signal is not received when the main body ECU has output the lock signal, the lock signal will be output again.
