      1. If the following conditions are met, the forced door lock control is operated.


        • The theft deterrent system is in the armed state.

        • Any door is unlocked.

  • INTRUSION SENSOR (THEFT WARNING ULTRASONIC SENSOR) (w/ Intrusion Sensor)

    Note

    Ultrasonic waves are used to detect intrusion. Ultrasonic waves do not penetrate steel or glass. If any of the windows 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 windows open. When parking the vehicle with the windows 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 cabin.

    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 arming preparation state. If an intrusion detection signal is input from the intrusion sensor (theft warning ultrasonic sensor) while in the armed state, the main body ECU (multiplex network body ECU) changes to the alarm sounding state in order to output an alarm.


      • All windows are closed:

        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.

      • Any window is opened:

        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.

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

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


      • Persons or pets are in the vehicle.

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

      • Ice or snow is removed from the vehicle, causing the vehicle to receive repeated impacts or vibrate.

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

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

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

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

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

  • CHECK INTRUSION SENSOR (THEFT WARNING ULTRASONIC SENSOR) (w/ Intrusion Sensor)


    1. Turn the power switch off.

    2. Make sure all of the windows and doors and the hood are closed.

    3. Lock all of the doors through wireless operation or the entry lock function*1 and check that the security indicator light illuminates (system changes to the arming preparation state).


      • *1: w/ Entry Function

    4. Approximately 30 seconds after locking all of the doors through wireless operation or the entry lock function*1, check that the security indicator light is blinking (system is in the armed state). Then, check that the alarm function operates (system changes to the alarm sounding state) due to movement inside the vehicle.

      Tech Tips

      If the electrical key transmitter sub-assembly is within an exterior detection area, the intrusion sensor (theft warning ultrasonic sensor) will not operate.*1


      • *1: w/ Entry Function

    5. Perform an unlock operation using the wireless, key linked power door lock or entry operation*1 to stop the alarm.


      • *1: w/ Entry Function

  • CHECK INTRUSION SENSOR CANCEL SWITCH (w/ Intrusion Sensor)


    1. Turn the power switch off.

    2. Make sure all of the windows and doors and the hood are closed.

    3. Press the intrusion sensor cancel switch and check that "Theft Sensor Turned Off" is displayed on the multi-information display.

    4. Lock all of the doors through wireless operation or the entry lock function and check that the security indicator light illuminates (system changes to the arming preparation state).

    5. Approximately 30 seconds after locking all of the doors through wireless operation or the entry lock function*1, check that the security indicator light is blinking (system is in the armed state). Then, check that the alarm function does not operate (system does not change to alarm sounding state) due to movement inside the vehicle.


      • *1: w/ Entry Function

      Tech Tips


      • Even if the intrusion sensor (theft warning ultrasonic sensor) is off, the theft deterrent system will be in the armed state. Therefore, if any of the doors is manually unlocked, the alarm will operate.

      • If the electrical key transmitter sub-assembly is within an exterior detection area, the intrusion sensor (theft warning ultrasonic sensor) will not operate.

  • GLASS BREAKAGE SENSOR (w/ Intrusion Sensor)


    1. The main body ECU (multiplex network body ECU) detects breakage of the glass breakage sensor (back door glass). If the main body ECU (multiplex network body ECU) detects breakage of the glass breakage sensor (back door glass) while the theft deterrent system is functioning, it will sound the alarm for 27.5 seconds.

  • THEFT WARNING SIREN ASSEMBLY (w/ Intrusion Sensor)


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

    2. The theft warning siren assembly 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) whereas under open circuit alarm control, the theft warning siren assembly judges current security conditions and sounds the alarm by itself.


      1. Normal alarm control

        The theft warning siren assembly 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 the communication between the theft warning siren assembly and main body ECU (multiplex network body ECU) is continuously interrupted for 70 seconds or more while the theft deterrent system is in the alarm sounding state, the theft warning siren assembly will stop sounding.

      2. A001QK6E05

        Open circuit alarm control

        The theft warning siren assembly changes between the disarmed state and armed state in accordance with the change of the theft deterrent system between the disarmed state and armed state. If the power source, ground or communication line becomes open while the theft warning siren assembly is in the armed state, the theft warning siren assembly will sound.

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

        This intermittent sounding will stop when either of the following conditions is met:

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

        2. The circuit returns to normal.

  • SECURITY INDICATOR LIGHT OUTPUT


    1. According to the state of the theft deterrent system, the main body ECU (multiplex network body ECU) outputs a signal to turn the security indicator light on. 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 Light
      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.
