System Description

WARNING: This page is about a different car, the 2007 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.
  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.
    • The alarm function will activate when someone attempts forcibly to lock any of the doors or open any of the doors, engine hood, and luggage door while the system is in the armed state.
    • In the alarm sounding state, the system illuminates the interior light and blinks the taillights, headlights, and hazard warning lights. At the same time, the system sounds the vehicle horns and security horn to deter break-in and theft as well as to warn people around the vehicle.
    • The theft deterrent system has 2 modes; one is the active arming mode  ) ACTIVE ARMING MODE) and the other is passive arming mode ( ) PASSIVE ARMING MODE). The passive arming mode can be switched ON/OFF using the specified method.
    • Each mode has 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:
      • Alarm function is operating.

        Alarm time:

        Condition (9) After approx. 60 sec., alarm stops and system returns to 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), 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 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:

        When the theft deterrent system has entered the alarm sounding state (tampering has been detected) even once, the taillights will light up for 2 seconds if any of the following conditions is met.

        • Switched to the disarmed state from the armed state during active arming mode.
        • Switched to the disarmed state 1 from the armed state during passive arming mode.

        HINT:

        Active arming mode:  ACTIVE ARMING MODE.

        Passive arming mode:  PASSIVE 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. Conditions that cause the panic alarm control to set off the panic alarm:

        The panic alarm control sets off the panic alarm by pressing the PANIC switch on the wireless transmitter under the following conditions:

        • The engine 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 engine switch is turned on (IG).
        • The panic alarm switch is turned on again.
        • Any of the switches on the wireless transmitter (LOCK/UNLOCK or LUGGAGE OPEN) 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 to passive arming mode.)
  8. SECURITY INDICATOR OUTPUT 
    1. The certification ECU outputs a signal to light up the security indicator, according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator are different from the output signals of the certification ECU.

      Output: 

      SECURITY INDICATOR REFERENCE CHART

      State of Theft Deterrent System(1) Security Indicator
      Output Signals from Certification ECU Actual Lighting Condition
      Disarmed state 1, 2 OFF OFF (Immobiliser system unset)
      BLINKING (Immobiliser system set)
      Arming preparation state ON ON
      Armed state OFF BLINKING
      Alarm sounding state ON ON
      (1) *: The above condition is common both to active arming mode and to passive arming mode.

      Blinking cycle: 

      BLINKING CYCLE REFERENCE CHART

      Time Security Indicator
      0.2 sec. ON
      1.8 sec. OFF

      HINT:

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