SYSTEM DESCRIPTION
1. OUTLINE OF THEFT DETERRENT SYSTEM
(a) When the theft deterrent system detects that the
vehicle is being tampered with, the system sets off
the alarm, causing the horns to sound and the lights
to light up or blink in order to alert people around the
vehicle to the theft.
(b) The theft deterrent system has 2 modes; one is the
active arming mode (see ACTIVE ARMING MODE)
and the other is passive arming mode (see
PASSIVE ARMING MODE). The passive arming
mode can be switched ON/OFF using the specified
method.
(c) Each mode has 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:
• Alarm function is operating.
Alarm time:
Approx. 60 sec.
Refer to table below for alarm method and time:
HINT:
If any of the doors are unlocked with no key in
the ignition key cylinder during the armed state,
a forced door lock signal will be output (see
FORCED DOOR LOCK CONTROL).
2. 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 items for each condition is met.
Alarm MethodHeadlight Blinking (approx. 0.4 second cycles)
Taillight Blinking (approx. 0.4 second cycles)

3. PASSIVE ARMING MODE
HINT:
• Passive arming mode starts the alarm control after
the key is removed from the ignition key cylinder 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

TDHINT:
*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 theft and
set off the alarm.
Entry delay time of 0, 14 or 30 sec. can be selected
by the customizing function.
4. FORCED DOOR LOCK CONTROL
