  • SECURITY INDICATOR LIGHT OUTPUT

    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.


    1. According to the state of the theft deterrent system, the certification ECU (smart key ECU assembly)*1 or body ECU*2 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 certification ECU (smart key ECU assembly)*1 or body ECU*2.

  • REMOTE ALARM FUNCTION (w/ Alarm Switch)


    1. Remote alarm function makes it possible to voluntarily set off the remote alarm by pressing the alarm switch on the electrical key transmitter sub-assembly.


      1. Conditions that cause remote alarm function to set off the remote alarm:

        The alarm switch on the electrical key transmitter sub-assembly is pressed under the following conditions:


        • The ignition switch is off.

        • The theft deterrent system is not in the alarm sounding state.

      2. Conditions that cause the remote alarm function to shut off the alarm:

        Any of the following conditions is met during remote alarm function operation:


        • The ignition switch is ON.

        • The alarm switch is pressed again.

        • Any of the switches on the electrical key transmitter sub-assembly (lock/unlock/back door open) is pressed.

        • The alarm ends (approximately 27.5 seconds have elapsed).

        • The theft deterrent system switches to the alarm sounding state. Under this condition, the theft deterrent system controls the alarm rather than the remote alarm function. In order to cancel this alarm, refer to the theft deterrent system alarm sounding state cancellation procedure.

  • 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. When any of the door 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 door windows open. When parking the vehicle with the door 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 vehicle interior.

    2. 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 body ECU changes to the alarm sounding state in order to output an alarm.

    3. 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.

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


      • 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 vibrations.

      • 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 when they drop or swing.

      • The system changes to the armed state even when 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.

  • THEFT WARNING SIREN ASSEMBLY (w/ Theft Warning Siren)


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

      2. B003JMBE02

        Open circuit alarm control

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

        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.

        The intermittent sounding will stop when either condition is met:

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

        2. The open circuit is returned to normal.

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


    1. Check that the engine hood is closed.

    2. Check the intrusion sensor (theft warning ultrasonic sensor) operation.


      1. Turn the ignition switch off.

      2. Lock all the doors using the wireless door lock or entry door lock function and check that the security indicator light illuminates (armed preparation state) (all windows need to be opened).

      3. Wait 30 seconds after locking all the doors using the wireless door lock or entry door lock function and check that the security indicator light blinks (armed state). Then, check that the theft deterrent system alarm operates due to movement inside the vehicle.

        Tech Tips

        If the electrical key transmitter is within the entry exterior area at this time, the alarm does not operate due to the intrusion sensor.

      4. Perform an unlock operation using the wireless or entry operation to stop the alarm.

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


    1. Check that the engine hood is closed.

    2. Check the intrusion sensor OFF switch operation.


      1. Turn the ignition switch off.

      2. Press the intrusion sensor OFF switch.

      3. Lock all the doors using the wireless door lock or entry door lock function and check that the security indicator light illuminates (armed preparation state).

      4. Approximately 30 seconds after locking all the doors via wireless operation or smart operation, check that the security indicator light changes to blinking (armed state) and the auto alarm does not operate according to movement in the cabin. At this time, do not bring the electrical key transmitter sub-assembly close to the smart exterior area.

        Tech Tips

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