THEFT DETERRENT SYSTEM SYSTEM DESCRIPTION


  1. OUTLINE OF THEFT DETERRENT SYSTEM


    • The theft deterrent system can be set by locking the doors using the transmitter.

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

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

    • The alarm can be cancelled by unlocking the doors using the transmitter.

    • 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:

        • After the first alarm, forced door lock control does operate.

  • SECURITY INDICATOR LIGHT OUTPUT


    1. The main body ECU (network gateway 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 (network gateway ECU).
