THEFT DETERRENT SYSTEM SYSTEM DESCRIPTION

OUTLINE OF THEFT DETERRENT SYSTEM

• The theft deterrent system can be set/canceled by locking/unlocking the doors using the following operation:

• 
  

  • Entry lock operation

  • Wireless lock operation

    Tip:

    • ○: Available

    • -: Not available

• The alarm function will be activated when someone attempts to forcibly unlock any of the doors or open any of the doors and engine hood while the system is in the armed state.

• In the alarm sounding state, the system blinks the hazard warning lights. At the same time, the system sounds the vehicle horn and security horn to deter break-in and theft as well as to warn people around the vehicle.

• The theft deterrent system has the active arming mode. There are 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:

   
   

   • The alarm function is operating.

   Alarm time
   Approximately 27.5 seconds

SECURITY INDICATOR LIGHT OUTPUT

1. According to the state of the theft deterrent system, the certification ECU (smart key ECU assembly)*1 or body ECU*2 outputs a signal to turn the security indicator light on. However, some of the actual lighting conditions of the security indicator light are different from the output signals of the certification ECU (smart key ECU assembly)*1 or body ECU*2.

   • *2: w/o Entry and Start System

REMOTE ALARM FUNCTION (w/ Alarm Switch)

1. Remote alarm function makes it possible to voluntarily set off the remote alarm by pressing the alarm switch on the electrical key transmitter sub-assembly.

   
   

   1. Conditions that cause remote alarm function to set off the remote alarm:

      The alarm switch on the electrical key transmitter sub-assembly is pressed under the following conditions:

      
      

      • The ignition switch is off.

      • The theft deterrent system is not in the alarm sounding state.

   2. Conditions that cause the remote alarm function to shut off the alarm:

      Any of the following conditions is met during remote alarm function operation:

      
      

      • The ignition switch is to ON.

      • The alarm switch is pressed again.

      • Any of the switches on the electrical key transmitter sub-assembly (lock/unlock) is pressed.

      • The alarm ends (approximately 27.5 seconds have elapsed).

      • The theft deterrent system switches to the alarm sounding state. Under this condition, the theft deterrent system controls the alarm rather than the remote alarm function. In order to cancel this alarm, refer to the theft deterrent system alarm sounding state cancellation procedure.

THEFT WARNING SIREN ASSEMBLY (w/ Theft Warning Siren Assembly)

1. The theft warning siren assembly has an internal battery. If power to the theft warning siren assembly is interrupted or the communication line is open, the theft warning siren assembly detects it and sounds the alarm using the internal battery.

2. The theft warning siren assembly has the following alarm controls: normal alarm control and open circuit alarm control. Under normal alarm control, the alarm sounds based on instructions from the body ECU whereas under open circuit alarm control, the theft warning siren assembly judges current security conditions and sounds the alarm by itself.

   
   

   1. Normal alarm control

      The theft warning siren assembly sounds when the theft deterrent system is in the alarm sounding state and does not sound when the system is not in the alarm sounding state.

      Tip:

      If communication interruption between the theft warning siren assembly and body ECU continues for 70 seconds or more while the theft deterrent system is in the alarm sounding state, the theft warning siren assembly stops sounding.

   2. 
      

      Open circuit alarm control

      The theft warning siren assembly changes between the disarmed state and armed state in accordance with the theft deterrent system changes between the disarmed state and armed state. If the power source, ground or communication line is open while the theft warning siren assembly is in the armed state, the theft warning siren assembly sounds.

      During the open circuit alarm sounding state, the theft warning siren assembly sounds intermittently for 27.5 seconds and then stops for 5 seconds. This pattern repeats a maximum of 9 times.

      The intermittent sounding will stop when either condition is met:

      1. The theft warning siren assembly changes to the disarmed state.

      2. The open circuit is returned to normal.
