THEFT DETERRENT SYSTEM
ON±VEHICLE INSPECTION
1. OUTLINE OF THEFT DETERRENT SYSTEM
(a) When the theft deterrent system detects that the vehicle is being tampered with, the sy\
stem 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 an active arming mode; 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.
HINT:
If the vehicle remains in a condition that sets off the alarm (any door remains open, engine hood remains
open, ignition switch remains directly connected) after the alarm ends,\
the alarm will be set off repeatedly
a maximum of 10 times for every one of the above specified conditions. Alarm time: Approx. 27.5 sec. x 10
(4) Alarm sounding state:When the theft deterrent system detects that the vehicle is being tampered w\
ith while in the
armed state, the system causes the horns to sound and the lights to light up or blink in order t\
o
alert people around the vehicle to the theft.
Refer to table below for alarm method and time:
Hazard Warning LampBlinking (Cycle of flasher relay)
Alarm MethodRoom LampIlluminatingAlarm MethodVehicle HornSounding (Cycle of 0.4 sec.)
Self±power SirenSounding (Cycle of 0.4 sec.)
Alarm TimeApprox. 27.5 sec. (Maximum 10 times)
HINT:
If any of the doors are unlocked with no key in the ignition key cylinde\
r during the armed state, a forced door
lock signal will be output (See step 3).

AVENSIS REPAIR MANUAL (RM1018E)
3. 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 doo\
r lock signal.
(1) Conditions that force the doors to lock:
When no key is in the ignition key cylinder and 0.4 seconds have elapsed aft\
er the previous out-
put of a forced door lock signal, the doors will be forced to lock if any o\
f the following conditions
is present.

The theft deterrent system is in the armed state of active arming mode.

All the doors are locked. Any door is unlocked.

Any door is unlocked.
HINT:
Only Europe:
Forced door lock control does not operate if any door is unlocked by key\
.
4. ALARM MEMORY FUNCTION
(a) If the alarm is set off (tampering is detected) while the theft deterrent system is set, the\
alarm memory function will record it. Whenever you cancel the theft deterrent system, the al\
arm memory function
causes the taillights to light up for 2 seconds in order to inform you t\
hat the alarm has been set off.
(1) Conditions of the alarm memory function that cause the taillights to lig\
ht 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
present.

Switched to the disarmed state from the armed state.
5. SECURITY INDICATOR OUTPUT
(a) The theft warning 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 d\
if-
ferent from the outputs of the theft warning ECU.
Output:

HINT:
When the immobiliser system is set, the security indicator blinks during the \
disarmed state and the armed
state, due to the output signals from the immobiliser system.

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERM\
INAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor\
.
Stop Light Disconnection Warning
When the ignition SW is turned on and the brake pedal is pressed (Stop ligh\
t SW on), if the stop light circuit is open, the cur
rent
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, \
so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sens\
or to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL \
8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turne\
d off.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major p\
arts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common \
ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

The
”Current Flow Chart” section, describes which parts each power source (fuses, fusible links\
, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the condition\
s when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power so\
urce, the power source system must be fully
understood.
