VEHICLE SECURITY SYSTEM : System Description

INFOID:0000000007563232

• The vehicle security system has two alarm functions (theft warning alarm and panic alarm), and reduces the

possibility of a theft or mischief by activating horns and headlamps intermittently.

• The panic alarm does not start when the theft warning alarm is activating, and the panic alarm stops when

the theft warning alarm is activated.
The priority of the functions are as per the following.

THEFT WARNING ALARM

• The theft warning alarm function activates horns and headlamps intermittently when BCM detects that any

door or trunk lid is opened by unauthorized means, while the system is in the ARMED state.

• Security indicator lamp always blinks when ignition switch is any position other than ON. Security indicator

lamp blinking warns that the vehicle is equipped with a vehicle security system.

SYSTEM

NOTE:

• BCM ignores the door key cylinder UNLOCK switch signal input for 1 second after the door key cylinder LOCK switch signal input.

• To lock/unlock all doors or trunk lid by operating remote controller button of Intelligent Key or door/trunk lid request switch, Intelligent

Key must be within the detection area of outside key antenna. For details, refer to

DLK-16, "DOOR LOCK FUNCTION : System

Description"

DISARMED Phase

The vehicle security system is not set in the DISARMED phase. The vehicle security system stays in this
phase while any door is open, because it is assumed that the owner is inside or nearby the vehicle. Security
indicator lamp blinks every 2.4 seconds.
When the vehicle security system is reset, each phase switches to the DISARMED phase directly.

PRE-ARMED Phase

The PRE-ARMED phase is the transient state between the DISARMED phase and the ARMED phase. This
phase is maintained for 30 seconds, so that the owner can reset the setting due to a mis-operation. This phase
switches to the ARMED phase when vehicle conditions are not changed for 30 seconds. Security indicator
lamp illuminates while being in this phase.
To reset the PRE-ARMED phase, refer to the switching condition of No. 10 in the table above.

ARMED Phase

The vehicle security system is set, and BCM monitors all necessary inputs. If any door or trunk lid is opened
without using Intelligent Key or mechanical key, vehicle security system switches to the ALARM phase. Secu-
rity indicator lamp blinks every 2.4 seconds.
If the theft warning alarm is activated irregularly when the customer opened trunk lid using mechanical key,
trunk key cylinder switch circuit might have a malfunction. Check the switch circuit. Refer to

SEC-97, "Compo-

nent Function Check"

To reset the ARMED phase, refer to the switching condition of No. 11 in the table above.

ALARM Phase

BCM transmits “Theft Warning Horn Request” signal and “High Beam Request” signal intermittently to IPDM
E/R via CAN communication. In this phase, horns and headlamps are activated intermittently for approxi-
mately 50 seconds to warn that the vehicle is accessed by unauthorized means. ON/OFF timings of horns and
headlamps are synchronized. After 50 seconds, the vehicle security system returns to the ARMED phase. At
this time, if BCM still detects unauthorized access to the vehicle, the system is switched to the ALARM phase
again. This RE-ALARM operation is carried out a maximum of 2 times.
To cancel the ALARM operation, refer to the switching condition of No. 12 in the table above.
NOTE:
If a battery terminal is disconnected during the ALARM phase, theft warning alarm stops. But when the battery
terminal is reconnected, theft warning alarm is activated again.

PRE-RESET Phase

The PRE-RESET phase is the transient state between each phase and DISARMED phase. If only the condi-
tion of trunk lid is not satisfied, the system switches to the PRE-RESET phase. Then, when any condition is
changed, the system switches to the DISARMED phase or PRE-ARMED phase.

PANIC ALARM

• The panic alarm function activates horns and headlamps intermittently when the owner presses the PANIC

ALARM button of Intelligent Key outside the vehicle while the Ignition switch position is OFF or LOCK.

• When BCM receives panic alarm signal from Intelligent Key, BCM transmits “Theft Warning Horn Request”

signal and “High Beam Request” signal intermittently to IPDM E/R via CAN communication. To prevent the
activation due to mis-operation of Intelligent Key by owner, the panic alarm function is activated when BCM
receives the signal for 0.4 - 0.6 seconds.

• Panic alarm operation is maintained for 25 seconds.
• Panic alarm operation is cancelled when BCM receives one of the following signals.

ARMED to
DISARMED

When one of the following
condition is satisfied.

• Ignition switch: ACC/ON/CRANKING/RUN
• Door key cylinder UNLOCK switch: ON
• UNLOCK button of Intelligent Key: ON
• Door request switch: ON

ALARM to
DISARMED

RE-ALARM

When one of the following
conditions is satisfied after

• Trunk lid: Open
