    • The alarm function will be activated when someone attempts to forcibly unlock any of the doors or open any of the doors, engine hood and back door 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:

        • *: w/o Entry and Start System

  • 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 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).
