SYSTEM DESCRIPTION

• The system reduces the possibility of a theft or mischief by sounding siren and blinking hazard warning lamp

continuously. The system activates siren and hazard warning lamp when detecting that the door or hood is
opened, or there is an illegal attempt to enter into the passenger room, while the system is in the ARMED
phase.

• Security indicator lamp on combination meter always blinks when ignition switch is any position other than

ON to warn that the vehicle is equipped with a VEHICLE SECURITY SYSTEM.

• Anti-theft function is improved by the adoption of intruder sensor that detects an attempt to enter into the

passenger room.

• Activation or deactivation of intruder sensor can be selected by sensor cancel switch.
• Siren control unit equips a built-in battery. Replace siren control unit once every 10 years because the war-

ranty for built-in battery expires after 10 years.

• Each time the system switches to the PRE-ARMED phase from the DISARMED phase, the self-diagnosis is

performed by the siren control unit and each sensor. If any malfunction is detected, the siren sounds* 5
times to inform the driver that a malfunction is detected and the vehicle security system does not function
properly. Malfunctioning part can be checked by “SIREN” in “ACTIVE TEST” mode of “THEFT ALM” of
“BCM” using CONSULT. Refer to

SEC-64, "Diagnosis Description"

.

*: Siren sounds for 0.2 seconds and sound interval is 0.4 seconds.

NOTE:

To lock/unlock all doors by operating remote controller button of Intelligent Key or door request switch, Intelligent Key must be within the
detection area of outside key antenna. For details, refer to

DLK-42, "DOOR LOCK FUNCTION : System Description"

(Type1) or

DLK-

352, "DOOR LOCK FUNCTION : System Description"

(Type2).

Disarmed Phase

VEHICLE SECURITY SYSTEM switches to the DISARMED phase while any doors or hood is open because it
is assumed that the owner is in or nearby the vehicle.

Pre-armed Phase

• VEHICLE SECURITY SYSTEM switches to the PRE-ARMED phase and blinks security indicator lamp

quickly for approximately 20 seconds when all doors are locked by Intelligent Key or door request switch,
while all doors and hood are closed.

• VEHICLE SECURITY SYSTEM that is in the PRE-ARMED phase switches to the DISARMED phase when

all doors are unlocked by Intelligent Key or door request switch or ignition switch is switched to the ON posi-
tion.

• VEHICLE SECURITY SYSTEM does not activate siren when door or hood is open while VEHICLE SECU-

RITY SYSTEM is in the PRE-ARMED phase. When the door or hood is closed again, VEHICLE SECURITY
SYSTEM stays in the PRE-ARMED phase.

Armed Phase

VEHICLE SECURITY SYSTEM switches to the ARMED phase from the PRE-ARMED phase after approxi-
mately 20 seconds, and blinks security indicator lamp slowly.

Alarm Phase

• VEHICLE SECURITY SYSTEM activates siren for approximately 27.5 seconds when any of the following

conditions is fulfilled while VEHICLE SECURITY SYSTEM is in the ARMED phase.

- When any door or hood is open
- When intruder sensor detects an attempt to enter into passenger compartment
- When battery connection is disconnected
- Communication between BCM and siren control unit is interrupted
- Communication between siren control unit and intruder sensor is interrupted
• VEHICLE SECURITY SYSTEM deactivates siren when door is unlocked by Intelligent Key or door request

switch, or the ignition switch is switched to the ON position while siren is activated.

• VEHICLE SECURITY SYSTEM switches to the ARMED phase automatically when approximately 5 sec-

onds pass after deactivating siren.

SENSOR CANCEL FUNCTION

Perform the following procedure to deactivate intruder sensor.

1.

CHECK SENSOR CANCEL FUNCTION

1.

Turn ignition switch OFF.

2.

Press sensor cancel switch, and before 5 minutes pass, close all doors and hood, and lock all doors using
the Intelligent Key or door request switch.

3.

Check that VEHICLE SECURY SYSTEM is switched to the PRE-ARMED phase and that the siren sounds
one beep.

NOTE:
Intruder sensor is not cancelled and return to normal operation when any of the following conditions is fulfilled
while the cancellation procedure is being performed.
• When ignition switch turns ON.
• When 5 minutes or more pass after pressing sensor cancel switch.
• When VEHICLE SECURITY SYSTEM switches to the DISARMED phase.
Does security indicator lamp blink quickly?

YES

>> INSPECTION END

NO

>> Check again.

ALARM PAUSE to
DISARMED
