THEFT DETERRENT SYSTEM SYSTEM DESCRIPTION


  1. OUTLINE OF THEFT DETERRENT SYSTEM


    • The theft deterrent system will operate when somebody attempts to forcibly enter the vehicle, unlock any door or luggage compartment door, or open the engine hood without using the key. This system causes the lights to light up and the horns or siren*1 (or security horn*2) to sound in order to deter break-in and theft.


      • The security indicator comes on or blinks to inform the driver that the alarm is set or not set.

      • The system locks all doors if any door is unlocked during the time that the alarm is activated.

      • The main body ECU RH controls this system.

    • 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.

      Tech Tips

      *: w/ Panic Switch

  • FORCED DOOR LOCK CONTROL


    1. The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (alarm starts), the door is forced to lock by a forced door lock signal.


      1. Conditions that force the doors to lock: When the key is not in the actuation area and both of the following conditions are met:


        • The theft deterrent system is in the alarm sounding state of active arming mode.

        • Any of the doors is unlocked.

  • OPERATION OF INTRUSION SENSOR


    1. An intrusion sensor is provided in the front interior light located in the front of the vehicle interior.

    2. The main body ECU RH activates the intrusion 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 during the armed state, the ECU changes to the alarm state in order to output an alarm.

    3. When the system is in the disarmed state, the function of the intrusion sensor can be disabled by pressing the satellite switch Click here.

    4. The intrusion sensor may erroneously detect intrusion in the following states:


      1. The system changes to the armed state even when any of the windows or sunroof is open. The intrusion sensor may react to objects moving outside the vehicle when any of the windows or sunroof is open.

      2. The intrusion sensor may react to a hanger or other objects hanging in the cabin when they drop or swing.

  • THEFT WARNING (SELF-POWER) SIREN (w/o Panic Switch)


    1. The theft warning siren assembly has an internal battery. If any of the vehicle's battery or communication lines are opened, the theft warning siren assembly detects it by itself and sounds. Although the theft warning siren assembly usually sounds by receiving a signal from the main body ECU RH.

    2. The main body ECU RH sends an arming signal to the theft warning siren assembly while switching to the armed state, as well as sending a disarming signal to the siren while switching to the disarmed state. Additionally, the main body ECU RH can sound the theft warning siren assembly by sending an alarm signal in the alarm sounding state.

  • PANIC ALARM CONTROL (w/ Panic Switch)


    1. The panic alarm control makes it possible to voluntarily set off the panic alarm by pressing the PANIC switch on the wireless transmitter.


      1. When the PANIC switch on the wireless transmitter is pressed, the panic alarm control sets off the panic alarm if any of the following conditions is met:


        • The engine switch is off.

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

      2. Conditions that cause the panic alarm control to shut off the alarm: Any of the following conditions is met during panic alarm operation:


        • The engine switch is turned on (IG).

        • The panic alarm switch is turned on again.

        • Either of the switches on the wireless transmitter (LOCK/UNLOCK/TRUNK) is pressed.

        • The panic alarm ends (approximately. 30 sec. have elapsed).

        • The theft deterrent system switches to the alarm sounding state. Under this condition, the theft deterrent system is controlling the alarm rather than the panic alarm control. In order to cancel this alarm, refer to the theft deterrent system alarm sounding state cancellation procedure.

        Tech Tips

        Active arming mode: See Active Arming Mode.

  • SECURITY INDICATOR OUTPUT


    1. The main body ECU RH outputs a signal to light up the security indicator, according to the state of the theft deterrent system.

      Output
      State of Theft Deterrent System Security Indicator
      Output Signal from Main Body ECU RH Actual Lighting Condition
      Disarmed state 1, 2

      OFF (Immobiliser system unset)

      BLINKING (Immobiliser system set)

      OFF (Immobiliser system unset)

      BLINKING (Immobiliser system set)

      Arming preparation state ON ON
      Armed state BLINKING BLINKING
      Alarm sounding state ON ON
      Blinking Cycle
      Time Security Indicator
      0.2 sec. ON
      1.8 sec. OFF

      Tech Tips


      • When the immobiliser system is set, the security indicator blinks during both the disarmed state and the armed state, due to the output signals from the immobiliser system.
