Operation Check

WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

    		 Armed state (alarm stops)
    HINT:
    *: When a door is opened while all other doors are closed during passive arming mode, the entry delay time starts. If the state switching condition [from armed state to disarmed state (1) or (2)] is fulfilled during the entry delay time, the theft deterrent system will return to disarmed state (1) or (2). However, if the state switching condition is not fulfilled, the theft deterrent system will assume that a break-in or theft is occurring and sounds the alarm.

    The entry delay time can be selected among the following: 0, 14 or 30 seconds.

  3. FORCED DOOR LOCK CONTROL 
    1. The forced door lock control also helps to prevent the vehicle from being tampered with. When a door is unlocked and the alarm starts, the door is forced to lock by a forced door lock signal.
      1. Conditions that force the doors to lock:
        • 0.4 seconds have elapsed after the previous output of a forced door lock signal.
        • The theft deterrent system is in the alarm sounding state of active arming mode.
        • A door is unlocked.
  4. PANIC ALARM CONTROL 
    1. The panic alarm control activates the panic alarm when the wireless transmitter PANIC switch is pressed. The panic alarm control operates independently from the theft deterrent system alarm control's change from the armed state to the alarm sounding state.
      1. Conditions that cause the panic alarm control to set off the panic alarm:

        The panic alarm is activated when the PANIC switch on the wireless transmitter is pressed and held for 2.4 seconds or more under the following conditions.

        • The ignition switch is OFF.
        • The theft deterrent system is not in the alarm sounding state.
        • The panic alarm control is not operating (the alarm is not set off).
      2. Conditions that cause the panic alarm control to shut off the alarm:

        The panic alarm is deactivated when any of the following conditions is fulfilled during panic alarm operation.

        • The ignition switch is turned ON.
        • The wireless transmitter lock/unlock switch is pressed.
        • 60 +/-5 seconds have passed and the panic alarm has ended.
        • The theft deterrent system changes to the alarm sounding state. However, the alarm still sounds, because the theft deterrent system has changed to the alarm sounding state.

        Conditions for canceling the panic alarm are the same as for the alarm control.

        HINT:

        For more information about active mode, refer to  1 for "ACTIVE ARMING MODE".

  5. ALARM MEMORY FUNCTION 
    1. If the alarm is set off (tampering is detected) while the theft deterrent system is in the armed state, the alarm memory function will record it. Whenever the theft deterrent system is canceled, the alarm memory function causes the taillights to illuminate 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 illuminate:

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

        • The system is changed to the disarmed state from the armed state during active arming mode.
        • The system is changed to the disarmed state (1) from the armed state during passive arming mode.

        HINT:

        For more information about active arming mode, refer to  1 for "ACTIVE ARMING MODE". For more information about passive arming mode, refer to  2 for "PASSIVE ARMING MODE".

  6. SECURITY INDICATOR OUTPUT 
    1. The security indicator turns on and off based on output signals from the main body ECU. However, in some cases, the actual status of the security indicator is different from the output signals of the main body ECU.

      Output 

      SECURITY INDICATOR OUTPUT REFERENCE

      State of Theft Deterrent System Security Indicator
      Output Signals from Main Body ECU Actual Lighting Condition
      Disarmed state OFF OFF (Engine immobiliser system not set)
      BLINKING (Engine immobiliser system set)
      Arming preparation state ON ON
      Armed state OFF BLINKING
      Alarm sounding state ON ON

      Blinking cycle 

      BLINKING CYCLE REFERENCE

      Time Security Indicator
      0.2 seconds ON
      1.8 seconds OFF

      HINT:

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