INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors and trunk (sedan).
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
and trunk (sedan) are closed and locked.
When a door or trunk (sedan) is open, BCM terminal 12, 13, 42, 43, 47 or 48 receives a ground signal from
each door or trunk switch. In addition to BCM, when back door is open, the Intelligent Key unit terminal 23
receives a ground signal from back door or trunk (sedan) through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
• Opening a door without using the key, keyfob or Intelligent Key.
• Opening trunk without using the key, keyfob or Intelligent Key (sedan).
The vehicle security system will be triggered once the system is in armed phase,
• when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), terminal 42
(sedan, trunk switch) or terminal 43 (hatchback, back door switch).
When the vehicle security system is triggered, ground is supplied intermittently
• from IPDM E/R terminal 45
• to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or trunk (sedan) must be unlocked with the key, keyfob or
Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal
• from terminal 3 of the front door key cylinder switch LH.
When the key is used to open the trunk (sedan), BCM terminal 41 receives signal
• from terminal 1 of the trunk key cylinder switch.
When the BCM receives an unlock signal from keyfob, Intelligent Key, front door key cylinder switch LH or
trunk key cylinder switch (sedan), the vehicle security system is deactivated (Disarmed phase).
PANIC ALARM OPERATION
Intelligent Key and remote keyless entry system may or may not operate vehicle security system (horn and
headlamps) as required.
When the remote keyless entry system is triggered, ground is supplied intermittently
