  1. OUTLINE OF THEFT DETERRENT SYSTEM 
    1. When the theft deterrent system detects that the vehicle is being tampered with, the vehicle horns and security horn will sound and hazard warning lights will flash continuously.
    2. The system has 2 modes- active arming mode (refer to "ACTIVE ARMING MODE" in step  2) and passive arming mode (refer to "PASSIVE ARMING MODE"* in step  3). Passive arming mode can be turned on and off using the intelligent tester or Techstream

      HINT

      *. Except Korea

    3. Each mode has 4 states, disarmed state, arming preparation state, armed state and alarm sounding state
    1. Disarmed state
      • The alarm function is not operating.
      • The theft deterrent system is not operating
    2. Arming preparation state.

      The theft deterrent system is not operating

    3. Armed state

      The theft deterrent system is operating.

    4. Alarm sounding state

      The alarm function is operating (60 +1-5 seconds).

    Refer to table below for alarm method and time:

    ALARM METHOD AND TIME REFERENCE

    HINT:

    * When a door is opened while all 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 sound the alarm. The entry delay time can be selected from among the following 0, 14 or 30 seconds.

  4. 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:
        • 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
  5. 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 power 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 power switch is turned ON (IG).
        • The wireless transmitter lock/unlock switch is pressed
        • +/-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 "ACTIVE ARMING MODE" in step  2

  6. 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 the driver 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 "ACTIVE ARMING MODE" For more information about passive arming mode, refer to "PASSIVE ARMING MODE" in step  3

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

      Output:

    INDICATOR OUTPUT REFERENCE

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

    Blinking cycle:

    TIME SPECIFICATION

    Time Security Indicator
    0 2 seconds ON
    1 8 seconds OFF

    HINT:

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