System Description

  1. OUTLINE OF THEFT DETERRENT SYSTEM 
    • The theft deterrent system can be set by locking the doors using the transmitter or key, or by opening and closing the doors (see  3Active Arming Mode or  4Passive Arming Mode for details).
    • The alarm function will be activated when someone attempts to forcibly unlock the driver side or passenger side doors or open any of the doors while the system is in the armed state.
    • 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.
    • The alarm can be cancelled by unlocking the doors using the transmitter or key.
    • 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's door is closed.
    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:

  4. PASSIVE ARMING MODE 

    HINT:

    • Passive arming mode starts the alarm control after the key is removed from the key cylinder and the doors are closed.
    • Passive arming mode can be switched ON/OFF using the Techstream.
    • The alarm is initially set (when shipped from the factory) to active arming mode (not passive arming mode).
    • During passive arming mode, the theft deterrent system goes into the armed state even if the doors are not locked.
    • Detecting that the doors are unlocked does not set off the alarm during passive arming mode.
    • A forced door lock signal is not output during passive arming mode (see  5Forced Door Lock Control).
    • Although the theft deterrent system detects that the doors are opened during passive arming mode, the alarm will not go off immediately because an entry delay time is set.
    • If condition (1) of active arming mode is met during passive arming mode, the theft deterrent system will switch to active arming mode.
    1. Passive arming mode:

      This system operates as described in the diagram below when one of the items for each condition is met.

      Condition (8) Approx. 60 seconds elapse. (The alarm stops and the system returns to the armed state.)
      HINT:
      *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.
  5. 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:
      1. The key is not in the key cylinder and both of the following conditions are met:
        • The theft deterrent system is in the alarm sounding state of active arming mode.
        • Any door is unlocked.
  6. 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:
        • When the theft deterrent system has entered into the alarm sounding state (tempering has been detected) even once.
        • When switched to disarmed state 1 from the armed state during passive arming mode.

          HINT:

          Active arming mode: See  3Active Arming Mode.

          Passive arming mode: See  4Passive Arming Mode.

  7. 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:
        • The ignition switch is off.
        • 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:

        • The ignition switch is turned to ON.
        • The panic alarm switch is turned on again.
        • Either of the switches on the wireless transmitter (LOCK/UNLOCK) is pressed.
        • The panic alarm ends (approx. 60 sec. have passed).
        • 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:

        • Active arming mode: See  3Active Arming Mode.
        • Passive arming mode: See  4Passive Arming Mode.
  8. 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.

      Output

      BLINKING (Immobilizer system set)
      Arming preparation state ON ON
      Armed state OFF BLINKING
      Alarm sounding state ON ON

      Blinking cycle 

      SECURITY INDICATOR CHART

      Time Security Indicator
      0.2 sec. ON
      1.8 sec. OFF

      HINT:

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

  9. GLASS BREAKAGE SENSOR 
    1. The glass breakage sensor detects impacts to or breakage of the glass. If the sensor detects any impacts or breakage while the theft deterrent system is functioning, it will sound an alarm for 60 seconds.
    2. The sensitivity of the glass breakage sensor can be adjusted by the volume switch in the glass breakage sensor ECU assembly.

      HINT:

      The glass breakage sensor may issue a false alarm if the sensor's sensitivity is set too high.
