4. PASSIVE ARMING MODE
HINT:
Passive arming mode starts the alarm control after the key is out of the actuation area and doors are closed.
Passive arming mode can be switched ON/OFF by the specified method.
The alarm is initially set (when shipped from 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 (see 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 the condition (1) of active arming mode is met during passive arming mode, the theft deterrent system will switch to active arming mode.

HINT: *1: When any door is opened while all the doors are closed 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 thef t 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 door is unlocked.
THEFT DETERRENT – THEFT DETERRENT SYSTEM (w/ Smart Key System)
6. ALARM MEMORY FUNCTION
(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 you that the alarm has been set off. (1) Conditions of the alarm memory function that
cause the taillights to light up: When the theft deterrent system has entered into the alarm sounding state (tampering has been detected) even once, the taillights will light up for 2 seconds if any of the following conditions is met.
Switched to the disarmed state from the armed state during active arming mode.
Switched to the disarmed state 1 from the armed state during passive arming mode.
HINT: Active arming mode: See ACTIVE ARMING MODE. Passive arming mode: See PASSIVE ARMING MODE.
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) Conditions that cause the panic alarm control to
set off the panic alarm: The panic alarm control sets off the panic alarm by pressing the PANIC switch on the wireless transmitter under the following conditions:
The engine switch 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.)
(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 on (IG).
The panic alarm switch is turned on again.
Any of the switches on the wireless transmitter (LOCK/UNLOCK or LUGGAGE OPEN) is pressed.
The panic alarm ends (approx. 60 sec. have passed).

TD–12
THEFT DETERRENT – THEFT DETERRENT SYSTEM (w/ Smart Key System)
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 to passive arming mode.)
HINT: Active arming mode: See ACTIVE ARMING MODE. Passive arming mode: See PASSIVE ARMING MODE.
8. SECURITY INDICATOR OUTPUT
(a) The certification ECU outputs a signal to light up the
security indicator, according to the state of the theft deterrent system. However, some of the actual lighting conditions of the security indicator are different from the output signals of the certification ECU.
Output:
State of Theft Deterrent System*
Disarmed state 1, 2 OFF Arming preparation state ON ON
Armed state OFF BLINKING Alarm sounding state ON ON
Output Signals from certification ECU Actual Lighting Condition

HINT:
*: The above condition is common both to active arming mode and to passive arming mode.
When the immobiliser system is set, the security indicator blinks during both the disarmed state and the armed state, due to the output signals from the immobiliser system.

NOTICE:
After confirming whether the items requested by the customer are applicable or not for customization, perform customizing operations.
Be sure to record the current settings before customization.
When troubleshooting, make sure that the item in question is not set to "OFF" as a result of customization (Example: For the system, "the wireless function does not operate", first check that the wireless function is not set to "OFF", then perform troubleshooting).
PASSIVE MODE is a function that switches theft deterrent system from arming preparation state to armed state 30 seconds after key is not in the actuation area and all doors, engine hood and luggage compartment door are closed, even if doors are not locked by wireless or door key lock operation In PASSIVE MODE, if you do not perform following operations within 14 seconds after door is opened during armed state, theft deterrent system will judge that condition as a theft and switch to alarm sounding state – Unlock any door by key or wireless operation – Turn the engine switch on (IG) – Open luggage compartment door by key or wireless

(b) Connect the cable of the intelligent tester (with CAN
VIM) to the DLC3, turn the engine switch on (IG) and attempt to use the intelligent tester. If the screen displays a communication error message, a problem exists in the vehicle or in the tester.
If communication is normal when the tool is connected to another vehicle, inspect the DLC3 on the original vehicle.
If communication is still impossible when the tool is connected to another vehicle, the problem is probably in the tool itself. Consult the Service Department listed in the tool's instruction manual.
