  • FORCED DOOR LOCK CONTROL


    1. The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (alarm starts), all doors are forced to lock by a forced door lock signal.


      1. Conditions that force the doors to lock:


        • The theft deterrent system is in the alarm sounding state of active arming mode.

        • Any door is unlocked.

  • OPERATION OF INTRUSION SENSOR (THEFT WARNING ULTRASONIC SENSOR) (w/ intrusion sensor Cancel Switch)

    Note

    Ultrasonic waves are used to detect intrusion. Ultrasonic waves do not penetrate steel or glass. When any of the door glasses or sliding roof is left open, ultrasonic waves may escape. This may result in the detection of people in the surroundings, leaves or insects entering the vehicle, strong wind or other ultrasonic wave sources in the environment when the vehicle is parked with the door glasses or sliding roof open. When parking the vehicle with the door glasses or the sliding roof open for ventilation, turn off the intrusion sensor (theft warning ultrasonic sensor) using the intrusion sensor cancel switch.


    1. An intrusion sensor (theft warning ultrasonic sensor) is provided in the map light assembly located in the front of the vehicle interior.

    2. The main body ECU (multiplex network body ECU) activates the intrusion sensor (theft warning ultrasonic sensor) when the system changes from the disarmed state to the armed preparation state. If an intrusion detection signal is input from the intrusion sensor (theft warning ultrasonic sensor) during the armed state, the main body ECU (multiplex network body ECU) changes to the alarm state in order to output an alarm.*1

    3. The main body ECU (multiplex network body ECU) activates the intrusion sensor (theft warning ultrasonic sensor) when the system changes from the disarmed state to the armed preparation state. If an intrusion detection signal is input after the glass breakage signal is input from the intrusion sensor (theft warning ultrasonic sensor) during the armed state, the main body ECU (multiplex network body ECU) changes to the alarm state in order to output an alarm.*2

    4. When the system is in the disarmed state, the function of the intrusion sensor (theft warning ultrasonic sensor) can be disabled by pressing the intrusion sensor cancel switch.

    5. The intrusion sensor (theft warning ultrasonic sensor) may erroneously detect intrusion in the following states:


      1. Persons or pets are in the vehicle.

      2. The vehicle is parked in a place where extreme vibrations or noises occur, such as in a parking garage.

      3. Ice or snow is removed from the vehicle, causing the vehicle to receive repeated impacts or vibrations.

      4. The wind or something similar causes an externally mounted reflectively coated windshield cover to move.

      5. The intrusion sensor (theft warning ultrasonic sensor) may react to a hanger or other objects hanging in the cabin when they drop or swing.

      6. The system changes to the armed state even when any of the windows or sunroof is open. The intrusion sensor (theft warning ultrasonic sensor) may react to objects moving outside the vehicle when any of the windows or sunroof is open.

      7. The vehicle is inside an automatic or high-pressure car wash.

      8. The vehicle experiences impacts, such as hail, lightning strikes and other kinds of repeated impacts or vibrations.


        • *1: except China

        • *2: for China

  • THEFT WARNING SIREN (w/ INTRUSION SENSOR Cancel Switch)


    1. The theft warning siren has an internal battery. If power to the theft warning siren is interrupted or any of the communication lines are open, the theft warning siren detects it and sounds the alarm using the internal battery.

    2. The theft warning siren has the following alarm controls: normal alarm control and open circuit alarm control. Under normal alarm control, the alarm sounds based on instructions from the main body ECU (multiplex network body ECU) assembly whereas under open circuit alarm control, the theft warning siren judges current security conditions and sounds the alarm by itself.


      1. Normal alarm control

        The theft warning siren sounds when the theft deterrent system is in the alarm sounding state and does not sound when the system is not in the alarm sounding state.

        Tech Tips

        If communication interruption between the theft warning siren and main body ECU (multiplex network body ECU) assembly continues for 70 seconds or more while the theft deterrent system is in the alarm sounding state, the theft warning siren stops sounding.

      2. A01G5CFE02

        Open circuit alarm control

        The theft warning siren changes between the disarmed state and armed state in accordance with the theft deterrent system change between the disarmed state and armed state. If +B, GND or the communication line is open while the theft warning siren is in the armed state, the theft warning siren sounds.

        During the open circuit alarm sounding state, the theft warning siren sounds intermittently for 27.5 seconds and then stops for 5 seconds and this pattern repeats a maximum of 9 times.

        The intermittent sound will stop when either condition is met:

        1. The theft warning siren changes to the disarmed state.

        2. The open circuit is returned to normal.

  • SECURITY INDICATOR OUTPUT


    1. The main body ECU (multiplex network body ECU) outputs a signal to turn on the security indicator light, according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator light are different from the output signals of the main body ECU (multiplex network body ECU).

      Output
      State of Theft Deterrent System Security Indicator Light
      Output Signal from Main Body ECU (Multiplex Network Body ECU) Actual Lighting Condition
      Disarmed state (1), (2) OFF

      OFF (Immobiliser system unset)

      BLINKING (Immobiliser system set)
      Arming preparation state ON ON
      Armed state OFF BLINKING
      Alarm sounding state ON ON
      Blinking Cycle
      Time Security Indicator
      0.125 sec. ON
      1.875 sec. OFF

      Tech Tips

      When the immobiliser system is set, the security indicator light blinks during both the disarmed state and the armed state due to output signals from the immobiliser system.
