THEFT DETERRENT / KEYLESS ENTRY: THEFT DETERRENT SYSTEM: SYSTEM DESCRIPTION
1. OUTLINE OF THEFT DETERRENT SYSTEM
* The theft deterrent system can be set by locking the doors using the transmitter or key, or by opening and closing the doors (for details, refer to Active Arming Mode or Passive Arming Mode).*1
* The theft deterrent system can be set by locking the doors using the transmitter or key.*2
* The alarm function will be activated when someone attempts to forcibly unlock any of the doors or open any of the doors, engine hood and luggage compartment door while the system is in the armed state.
* In the alarm sounding state, the system illuminates the interior light*1 and blinks the hazard warning lights, headlights*1 and taillights*1. At the same time, the system sounds the vehicle horns and security horn to deter break-in and theft as well as to warn people around the vehicle.
* The alarm can be cancelled by unlocking the doors using the transmitter or key.
* There are two arming modes for this system: one is active arming mode and the other is passive arming mode.*1 When the active arming mode has been set, the theft deterrent system will be set after the user locks the doors via the transmitter or key.*1 When the passive arming mode has been set, the theft deterrent system will be set after the key is removed and the driver door is closed.*1
(a) Disarmed state:
* The alarm function is not operating.
* The theft deterrent system is not operating.
(b) Arming preparation state:
* The time until the system goes into the armed state.
* The theft deterrent system is not operating.
(c) Armed state:
* The theft deterrent system is operating.
(d) Alarm sounding state:
* The alarm function is operating.
Alarm time:
Approx. 60 seconds*1
Approx. 30 seconds*2
Alarm Method and Time
* *1: W/ Satellite Radio
* *2: W/O Satellite Radio
HINT
If any of the doors are unlocked when the key is not in the actuation area during the armed state, a forced door lock signal will be output (see Forced Door Lock Control).
2. FUNCTION OF MAIN COMPONENT
* *: W/ Satellite Radio
3. ACTIVE ARMING MODE
HINT
* Active arming mode starts the alarm control immediately after the doors are locked.
* This system activates as described in the diagram below when one of the items for each condition is met.
(a) Active arming mode
* *1: W/ Satellite Radio
* *2: W/O Satellite Radio
4. PASSIVE ARMING MODE (W/ Satellite Radio)
HINT
* Passive arming mode starts the alarm control after the key is removed from the detection area and the doors are closed.
* Passive arming mode can be switched on/off using the Techstream.
* The alarm is initially set (when shipped from the factory) to active arming mode (not passive arming mode).
* During passive arming mode, the theft deterrent system goes into the armed state even if the doors are not locked.
* Detecting that the doors are unlocked does not set off the alarm during passive arming mode.
* A forced door lock signal is not output during passive arming mode (refer to Forced Door Lock Control).
* Although the theft deterrent system detects that the doors are opened during passive arming mode, the alarm will not go off immediately because an entry delay time is set.
* If condition (1) of active arming mode is met during passive arming mode, the theft deterrent system will switch to active arming mode.
(a) Passive Arming Mode
HINT
*: If any door is opened during passive arming mode, the entry delay time starts. If the switch condition (armed state -> disarmed state 1 or 2) is met during the entry delay time, the theft deterrent system will return to disarmed state 1 or 2. However, if the switch condition for disarmed state 1 or 2 is not met, the theft deterrent system will recognize it as a theft and set off the alarm. Entry delay time of 0, 14 or 30 sec. can be selected by the customizing function.
5. FORCED DOOR LOCK CONTROL
(a) The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (alarm starts), the door is forced to lock by a forced door lock signal.
(1) Conditions that force the doors to lock: When the key is not in the actuation area and both of the following conditions are met:
* The theft deterrent system is in the alarm sounding state of active arming mode.
* Any of the door is unlocked.
6. ALARM MEMORY FUNCTION (W/ Satellite Radio)
(a) If the alarm is set off (tampering is detected) while the theft deterrent system is armed, it will be recorded by the alarm memory function. Whenever the theft deterrent system is cancelled, the alarm memory function causes the taillights to light up 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 light up for 2 seconds:
* When the theft deterrent system has entered into the alarm sounding state (tempering has been detected) even once.
* When switched to disarmed state 1 and disarmed state 2 from the armed state.
HINT

7. PANIC ALARM CONTROL
(a) The panic alarm control makes it possible to voluntarily set off the panic alarm by pressing the panic switch on the wireless transmitter.
(1) When the panic switch on the wireless transmitter is pressed, the panic alarm control sets off the panic alarm if any of the following conditions is met:
* The engine switch is off.
* The theft deterrent system is not in the alarm sounding state. (This condition is common both to active arming mode and to passive arming mode.)*1
(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 met during panic alarm operation:
* The engine switch is turned on (IG).
* The panic alarm switch is turned on again.
* Any of the switches on the wireless transmitter (lock/unlock/trunk) is pressed.
* The panic alarm ends (approx. 60 sec.*1 or approx. 30 sec.*2 have passed).
* The theft deterrent system switches to the alarm sounding state. Under this condition, the theft deterrent system is controlling 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. (This condition is common both to active arming mode and to passive arming mode.)*1
HINT
Active arming mode: See Active Arming Mode.*1 Passive arming mode: See Passive Arming Mode.*1
* *1: W/ Satellite Radio
* *2: W/O Satellite Radio
8. SECURITY INDICATOR OUTPUT
(a) The main body ECU RH (cowl side junction block RH) outputs a signal to light up the security indicator, according to the state of the theft deterrent system.
Output
Blinking Cycle
HINT
* *: The above condition is common both to active arming mode and to passive arming mode.
* When the immobilizer system is set, the security indicator blinks during both the disarmed state and the armed state, due to the output signals from the immobilizer system.
