Theft Deterrent System -- On-Vehicle Inspection


HINT:
Before checking the theft deterrent system function, cancel the entry and start system.


1. OUTLINE OF THEFT DETERRENT SYSTEM

  1. When the theft deterrent system detects that the vehicle is being tampered with, the horns sound and lights flash continuously. For Europe, Russia, Turkey and China models, theft warning siren sounds simultaneously.

  1. The system has 2 modes: active arming mode (see step 2) and passive arming mode (see step 3). Passive arming mode can be turned on and off using the intelligent tester.

  1. Each mode has 4 states: disarmed state, arming preparation state, armed state and alarm sounding state.

    1. Disarmed state:

      1. The alarm function is not operating.
      2. The theft deterrent system is not operating.

    2. Arming preparation state:

      1. The theft deterrent system is not operating.

    3. Armed state:

      1. The theft deterrent system is operating.

    4. Alarm sounding state:

      1. The alarm function is operating (30 +- 5 seconds).

      Refer to table below for alarm method and time:
      Alarm Method
      		Hazard Warning Light
      		Blinking (cycle of flasher relay)
      Vehicle Horn
      		Sounding (cycle of 0.4 seconds)

      Alarm Time
      		30 +- 5 seconds
      HINT:
      If, during the alarm sounding state, one of the doors is unlocked without using the proper key, a forced door lock signal will be output (see step 4).

4. Armed state (alarm stops)
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 transfer 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 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:

      1. 0.4 seconds have elapsed after the previous output of a forced door lock signal.
      2. The theft deterrent system is in the alarm sounding state of active arming mode.
      3. A door is unlocked.


5. PANIC ALARM CONTROL (OPTIONAL FUNCTION)

  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 control sets off the panic alarm when the PANIC switch on the wireless transmitter is pressed for over 2.4 seconds under the following conditions.

      1. The engine switch is off.
      2. The theft deterrent system is not in the alarm sounding state.
      3. 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 control shuts off the panic alarm when any of the following conditions is fulfilled during panic alarm operation.

      1. The engine switch is turned on.
      2. The wireless transmitter lock / unlock switch is pressed.
      3. 60 + - 5 seconds have pressed and the panic alarm has ended.
      4. The theft deterrent system switches to the alarm sounding state. However, the alarm is still sounding, because the theft deterrent system has switched to the alarm sounding state.
        Conditions for canceling the panic alarm are the same as for the alarm control.
      HINT:
      For more information about the active mode, see 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 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 either of the following conditions is fulfilled.

      1. This system changed to the disarmed state from the armed state during active arming mode.
      2. This system changed to the disarmed state (1) from the armed state during passive arming mode.
      HINT:
      For more information about active arming mode, see step 2. For more information about passive arming mode, see step 3.


7. SECURITY INDICATOR OUTPUT

  1. The security indicator turns on and off based on output signals from the multiplex network body ECU. However, in some cases, the actual status of the security indicator is different from the output signals of the multiplex network body ECU.

    Output:
    State of Theft Deterrent System
    		Security Indicator
    Output Signals from Body ECU
    		Actual Lighting Condition
    Disarmed state
    		OFF
    		OFF (Immobiliser system not set)

    		ON
    1.8 seconds
    		OFF

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