FORCED DOOR LOCK CONTROL

The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (armed state), all doors are forced to lock by a forced door lock signal.
1. If the following conditions are met, the forced door lock control is operated.
  - The theft deterrent system is in the armed state.
  - Any door is unlocked.

PANIC ALARM CONTROL (w/ Panic Switch)

Panic alarm control makes it possible to voluntarily set off the panic alarm by pressing the panic switch on the electrical key transmitter sub-assembly.
1. Conditions that cause panic alarm control to set off the panic alarm:
  
  The panic switch on the electrical key transmitter sub-assembly is pressed under the following conditions:
  - The engine switch is off.
  - The theft deterrent system is not in the alarm sounding state.
2. Conditions that cause the panic alarm control to shut off the alarm:

  - The panic switch is pressed again.
  - Any of the switches on the electrical key transmitter sub-assembly (lock/unlock/luggage open) is pressed.
  - The panic 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 panic alarm control. In order to cancel this alarm, refer to the theft deterrent system alarm sounding state cancellation procedure.

INTRUSION SENSOR (THEFT WARNING RADAR SENSOR) (w/ Intrusion Sensor Cancel Switch)

Note

Ultrasonic waves are used to detect intrusion. Ultrasonic waves do not penetrate steel or glass. When any of the door windows is left open, ultrasonic waves may escape. This may result in the detection of people in the surroundings, leaves or insects entering the vehicle, strong wind or other ultrasonic wave sources in the environment when the vehicle is parked with the door windows open. When parking the vehicle with the door windows open for ventilation, turn off the intrusion sensor (theft warning radar sensor) using the intrusion sensor cancel switch.

An intrusion sensor (theft warning radar sensor) is provided in the map light assembly located in the front of the vehicle interior.
The main body ECU (multiplex network body ECU) activates the intrusion sensor (theft warning rada sensor) when the system changes from the disarmed state to the armed preparation state. If an intrusion detection signal is input from the intrusion sensor (theft warning radar sensor) during the armed state, the main body ECU (multiplex network body ECU) changes to the alarm sounding state in order to output an alarm.
The main body ECU (multiplex network body ECU) activates the intrusion sensor (theft warning radar sensor) when the system changes from the disarmed state to the armed preparation state.
- All windows are closed:
  
  If an intrusion detection signal is input after the glass breakage signal is input from the intrusion sensor (theft warning radar sensor) during the armed state, the main body ECU (multiplex network body ECU) changes to the alarm state in order to output an alarm.
- Any window is opened:
  
  If an intrusion detection signal is input from the intrusion sensor (theft warning radar sensor) during the armed state, the main body ECU (multiplex network body ECU) changes to the alarm state in order to output an alarm.
When the system is in the disarmed state, the function of the intrusion sensor (theft warning radar sensor) can be disabled by pressing the intrusion sensor cancel switch.
The intrusion sensor (theft warning radar sensor) may erroneously detect intrusion in the following states:
- Persons or pets are in the vehicle.
- The vehicle is parked in a place where extreme vibrations or noises occur, such as in a parking garage.
- Ice or snow is removed from the vehicle, causing the vehicle to receive repeated impacts or vibrations.
- The wind or something similar causes an externally mounted reflectively coated windshield cover to move.
- The intrusion sensor (theft warning radar sensor) may react to a hanger or other objects hanging in the cabin when they drop or swing.
- The system changes to the armed state even when any of the windows is open. The intrusion sensor (theft warning radar sensor) may react to objects moving outside the vehicle when any of the windows is open.
- The vehicle is inside an automatic or high-pressure car wash.
- The vehicle experiences impacts, such as hail, lightning strikes and other kinds of repeated impacts or vibrations.

TILT SENSOR (YAW RATE SENSOR) (w/ Tilt Sensor)

The tilt sensor (yaw rate sensor) detects the pitch angle of vehicle inclination using 2 deceleration sensors. When the tilt sensor (yaw rate sensor) detects a change in the pitch angle of vehicle inclination, such as a thief attempting to tow the vehicle, it transmits the warning signal to the main body ECU (multiplex network body ECU).
The main body ECU (multiplex network body ECU) activates the tilt sensor (yaw rate sensor) when the system changes from the armed preparation state to the armed state. If a warning signal is received from the tilt sensor (yaw rate sensor) when in the armed state, the main body ECU (multiplex network body ECU) changes to the alarm sounding state in order to sound the alarm.
When the system is in the disarmed state, pressing the intrusion sensor cancel switch disables the function of the tilt sensor (yaw rate sensor). If the system changes to the armed state, the tilt sensor (yaw rate sensor) will not activate. This function is canceled each time all doors are unlocked by the wireless operation, entry and start system or key linked power door lock operation, and is reinstated when the tilt sensor (yaw rate sensor) is on.
Under the following conditions, if the vehicle tilts or acceleration in the vertical or horizontal direction is detected by the tilt sensor (yaw rate sensor), the alarm may activate accidentally. To avoid accidental alarm activation, turn the tilt sensor (yaw rate sensor) off using the intrusion sensor cancel switch.
- The vehicle is transported by a ferry, trailer or train.
- The vehicle is parked in a multi-story parking facility.
- The vehicle is washed by a conveyor type car washing machine.
- A tire blows out.
- The vehicle is jacked up for a tire or wheel change.
- An earthquake occurs or the road subsides.
- Goods such as skis or snowboards are loaded or unloaded.

THEFT WARNING SIREN ASSEMBLY (w/o Security Horn Assembly)

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.
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 main body ECU (multiplex network 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.
  
  Tech Tips
  
  If communication interruption between the theft warning siren assembly and main body ECU (multiplex network 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.

SECURITY INDICATOR LIGHT OUTPUT

According to the state of the theft deterrent system, the main body ECU (multiplex network body ECU) 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 main body ECU (multiplex network body ECU).

Output
State of Theft Deterrent System	Security Indicator Light
State of Theft Deterrent System	Output Signal from Main Body ECU (Multiplex Network Body 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

Blinking Cycle
Time	Security Indicator Light
0.125 seconds	On
1.875 seconds	Off

Tech Tips

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

CHECK INTRUSION SENSOR (THEFT WARNING RADAR SENSOR) (w/ Intrusion Sensor Cancel Switch)

Check that the hood is closed.
Check the intrusion sensor (theft warning radar sensor) operation.
1. Turn the engine switch off.
2. Lock all the doors using the wireless door lock or entry door lock function and check that the security indicator light illuminates (armed preparation state) (all windows need to be opened).
3. Wait 30 seconds after locking all the doors using the wireless door lock or entry door lock function and check that the security indicator light blinks (armed state). Then, check that the theft deterrent system alarm operates due to movement inside the vehicle.
  
  Tech Tips
  
  If the electrical key transmitter is within the entry exterior area at this time, the alarm does not operate due to the intrusion sensor.
4. Perform an unlock operation using the wireless or entry operation to stop the alarm.

CHECK INTRUSION SENSOR CANCEL SWITCH (w/ Intrusion Sensor Cancel Switch)

Check that the hood is closed.
Check the intrusion sensor cancel switch operation.
1. Turn the engine switch off.
2. Press the intrusion sensor cancel switch and check that "Theft sensor OFF" is displayed on the combination meter.
3. Lock all the doors using the wireless door lock or entry door lock function and check that the security indicator light illuminates (armed preparation state).
4. Approximately 30 seconds after locking all the doors via wireless operation or entry operation, check that the security indicator light changes to blinking (armed state) and the auto alarm does not operate according to movement in the cabin. At this time, do not bring the electrical key transmitter sub-assembly close to the smart exterior area.
  
  Tech Tips
  
  Even if the intrusion sensor (theft warning radar sensor) is off, the theft deterrent system is in the armed state. Therefore, if any of the doors is manually unlocked, the alarm operates.
