Theft Deterrent System -- System Description



OUTLINE OF THEFT DETERRENT SYSTEM
  1. The theft deterrent system can be set by locking the doors using the transmitter or key, or by opening and closing the doors (see Active Arming Mode or Passive Arming Mode for details).
  2. The alarm function will be activated when someone attempts to forcibly unlock the any of the doors, open any of the doors or the luggage compartment door while the system is in the armed state.
  3. In the alarm sounding state, the system illuminates the interior light and blinks the hazard warning lights, the headlights and taillights. 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.
  4. The alarm can be cancelled by unlocking the doors using the transmitter or key.
  5. There are two arming modes for this system: active arming mode and passive arming mode. When the active arming mode has been set, the theft deterrent system will be set after the user locks the doors via the transmitter or key. When the passive arming mode has been set, the theft deterrent system will be set after the key is removed and the driver door is closed.

    1. *: When any door is opened while all the doors are closed during passive arming mode, the entry delay time starts. If the switch condition (armed state → disarmed state (1) or (2)) is met during the entry delay time, the theft deterrent system will return to disarmed state (1) or (2). However, if the switch condition for disarmed state (1) or (2) is not met, the theft deterrent system will recognize it as a theft and set off the alarm. Entry delay time of 0, 14 or 30 sec. can be selected by the customizing function.

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), all doors are forced to lock by a forced door lock signal.

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

      1. The theft deterrent system is in the alarm sounding state of active arming mode.
      2. Any door is unlocked.

ALARM MEMORY FUNCTION

  1. If the alarm is set off (tampering is detected) while the theft deterrent system is armed, it will be recorded by the alarm memory function. Whenever the theft deterrent system is cancelled, the alarm memory function causes the taillights to light up for 2 seconds in order to inform you that the alarm has been set off.

    1. Conditions of the alarm memory function that cause the taillights to light up for 2 seconds:

      1. When the theft deterrent system has entered into the alarm sounding state (tempering has been detected) even once.
      2. When switched to disarmed state 1 from the armed state during passive arming mode.
      HINT:
      Active arming mode: See Active Arming Mode.
      Passive arming mode: See Passive Arming Mode.

PANIC ALARM CONTROL

  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:

      1. The ignition switch is off.
      2. The theft deterrent system is not in the alarm sounding state. (This condition is common both to active arming mode and to passive arming mode.)

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

      1. The ignition switch is turned to ON.
      2. The panic alarm switch is turned on again.
      3. Either of the switches on the wireless transmitter (LOCK/UNLOCK/TRUNK OPENER) is pressed.
      4. The panic alarm ends (approx. 57 sec. have elapsed).
      5. 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. (This condition is common both to active arming mode and to passive arming mode.)
      HINT:
      1. Active arming mode: See Active Arming Mode.
      2. Passive arming mode: See Passive Arming Mode.

SECURITY INDICATOR OUTPUT

  1. The main body ECU outputs a signal to come on the security indicator light assembly, according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator light assembly are different from the output signals of the main body ECU.
