THEFT DETERRENT SYSTEM(w/o Entry and Start 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:

      - Wireless lock operation

      - Key linked lock operation

      - By opening and closing the doors

    • In the armed state, the alarm function will be activated if one of the following conditions is met:

      - Any of the doors are unlocked.

      - Any of the doors, the engine hood or the back door is opened.

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

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

      - Wireless lock operation

    • The theft deterrent system has an active arming mode. There are 4 states in this mode: 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:

      Condition [8]

      One of the following conditions is met:


      • Any door is opened.

      • Key is in the key cylinder.

      • The ignition switch is turned to ON.

      • The battery is reconnected.

      • All doors are unlocked by wireless operation or key linked power door lock operation.
      Condition [9]

      In disarmed state 1, when the ignition switch is off, the system state is switched if the following condition is met:


      • With all doors closed and the engine hood open, all doors are locked by wireless operation or key linked power door lock operation.

      In disarmed state 1, when the ignition switch is off, the engine hood and back door are open and all doors are locked, the system state is switched if the following condition is met:


      • The state changes from any of the doors being opened to all doors being closed.
      Condition [10]

      • The engine hood is opened.

  • FORCED DOOR LOCK CONTROL


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


      1. If the following conditions are met, the forced door lock control is operated.


        • The theft deterrent system is in the armed state.

        • Any door is unlocked.

  • SECURITY INDICATOR LIGHT OUTPUT


    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).

      Output
      State of Theft Deterrent System Security Indicator Light
      Output Signal from Main Body ECU (Multiplex Network Body ECU) Actual Lighting Condition
      Disarmed state (1), (2) OFF

      Off (Engine immobiliser system unset)

      Blinking (Engine immobiliser system set)
      Arming preparation state ON On
      Armed state OFF Blinking
      Alarm sounding state ON On
      Blinking Cycle
      Time Security Indicator Light
      0.125 seconds On
      1.875 seconds Off

      Tech Tips

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