THEFT DETERRENT – THEFT DETERRENT SYSTEMTD–3
TD
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)
Hazard Warning Light Blinking (cycles of flasher relay)
Interior Light Illuminating
Vehicle HornSounding
(approx. 0.4 second cycles)
Security HornSounding
(approx. 0.4 second cycles)
Alarm Time Approx. 60 sec.

5. 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
you cancel the theft deterrent system, 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.
6. 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 for over 2, 4 seconds under the
following conditions:
• The ignition 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.)
(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 ignition switch is turned ON.
• Either of the switches on the wireless
transmitter (LOCK/UNLOCK) is pressed.
• The panic alarm ends (60 sec. have passed).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of
a malfunction.
(a) Check whether the stop lights turn on and off normally
when the brake pedal is depressed and released.
OK:
Stop lights turn on when brake pedal is depressed.
