VEHICLE SECURITY SYSTEM : System Description
INFOID:0000000006226185
 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 hood is opened by unauthorized means, whil e the system is in the ARMED state.
 Security indicator lamp on combination meter always blinks when power supply position is any position other
than ON. Security indicator lamp blinking warns that the vehicle is equipped with a vehicle security 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 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-18, "
INTELLIGENT KEY SYSTEM : System Description".
 To open back door by operating back door opener switch, Intelligent Key must be within the detection area of outside key anten na. For
details, refer to DLK-18, "
INTELLIGENT KEY SYSTEM : System Description".
DISARMED Phase
The vehicle security system is not set in the DISARM ED 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 bet ween the DISARMED phase and the ARMED phase. This
phase is maintained for 30 seconds, so that the owner c an 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 hood is opened with-
out using Intelligent Key, vehicle security system switc hes to the ALARM phase. Security indicator lamp blinks
every 2.4 seconds.
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 timing of horns and
headlamps are synchronized. After 50 seconds, the vehi cle security system returns to the ARMED phase. At
6ARMED to
PRE-RESET No conditions.

SYSTEM
this time, if BCM still detects unauthorized access to t
he 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 betw een each phase and DISARMED phase. If only the condi-
tion of hood is not satisfied, the system switches to the PRE-RESET phase. Then, when any condition is
changed, the system switches to t he 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 power supply 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 ow ner, 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.
- LOCK button of Intelligent Key: ON
- UNLOCK button of Intelligent Key: ON
- PANIC ALARM button of Intelligent Key: Long pressed
- Any door request switch: ON
