(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.

• 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.

THEFT DETERRENT – THEFT DETERRENT SYSTEM (w/o Smart Key System)

• 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

THEFT DETERRENT – THEFT DETERRENT SYSTEM (w/o 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.

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 main body 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 main body
ECU.

Output:

Security Indicator Light Circuit

DESCRIPTION

Even when the theft deterrent system is in the disarmed state, the security indicator blinks du e to a signal
output from the immobiliser system. The security indicator blinks continuously due to a continuous signal
received from the immobiliser system while in the armed state.
The main body ECU causes the security indicator to light up or blink only during the arming preparation
state and alarm sounding states.
