*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.

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)
