THEFT DETERRENT SYSTEM SYSTEM DESCRIPTION


  1. OUTLINE OF THEFT DETERRENT SYSTEM


    • The theft deterrent system can be set/canceled by locking/unlocking the doors using the following operation:


      • Entry lock operation

      • Wireless lock operation

        Tech Tips

        w/ Smart Entry and Start System w/o Smart Entry and Start System
        Entry lock operation ○ -
        Wireless lock operation ○ ○

        • ○: Available

        • -: Not available

    • The alarm function will be activated when someone attempts to forcibly unlock any of the doors or open any of the doors and engine hood while the system is in the armed state.

    • In the alarm sounding state, the system blinks the hazard warning lights. At the same time, the system sounds the vehicle horn and security horn to deter break-in and theft as well as to warn people around the vehicle.

    • The theft deterrent system has the active arming mode. There are 4 states; a disarmed state, an arming preparation state, an armed state and an alarm sounding state.


    1. Disarmed state:


      • The alarm function is not operating.

      • The theft deterrent system is not operating.

    2. Arming preparation state:


      • The time until the system goes into the armed state.

      • The theft deterrent system is not operating.

    3. Armed state:


      • The theft deterrent system is operating.

    4. Alarm sounding state:


      • The alarm function is operating.

  • 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


    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 (IG).

        • 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.
