VEHICLE SECURITY (THEFT WARNING) SYSTEM
System Description
INFOID:0000000001327905
DESCRIPTION
Operation Flow
Setting the Vehicle Security System
Initial condition
Ignition switch is in OFF position.
Disarmed phase
When hood, doors or back door is open, the vehicle secu rity system is set in the disarmed phase on the
assumption that the owner is inside or near the vehicle.
When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4 sec-
onds.
Pre-armed phase and armed phase
When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”
phase. (The security indicator lamp illuminates.)
1. BCM receives LOCK signal from front door key cyli nder switch, key fob or Intelligent Key after hood, back
door and all doors are closed.
2. Hood, back door and all doors are closed after front doors are locked by key or door lock and unlock
switch.
The security indicator lamp illuminates for 30 sec onds. then, the system automatically shifts into the
“armed” phase.
Canceling the Set Vehicle Security System
When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the key, key fob or Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.
Canceling the Alarm Operation of the Vehicle Security System
When unlock the door with the key, key fob or Intelligent Key the alarm operation is canceled.

Make sure the system is in the armed phase. (The security indicator lamp brinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, t he system sounds the horns and flashes the headlamps for
about 50 seconds.
1. Hood, back door or any door is opened during armed phase.
2. Disconnecting and connecting the battery connector before canceling armed phase.
POWER SUPPLY
Power is supplied at all times
through 10A fuse [No.19, located in the fuse block (J/B)]
to security indicator lamp terminal 1.
through 50A fusible link (letter M, located in the fuse and fusible link box)
to BCM terminal 55.
through 15A fuse [No.22, located in the fuse block (J/B)]
to BCM terminal 42.
through 15A fuse [No.34, located in the fuse and fusible link box]
to horn relay terminal 2.
through 10A fuse [No.71, located in the IPDM E/R]
to IPDM E/R internal CPU.
through 15A fuse [No.78, located in the IPDM E/R]
to IPDM E/R internal CPU.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in the fuse block (J/B)]
to BCM terminal 11.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and back door.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and back door
are closed and the doors are locked by key fob, Intelligent Key or ignition key.
When a door is open, BCM terminal 12 (passenger side door), 13 (rear RH door), 62 (driver side door), 63
(rear LH door) receives a ground signal from each door switch.
When front door LH is unlocked by power window main switch (door lock and unlock switch),
BCM terminal 22 receives a signal from terminal 14 of power window main switch with power window serial
link.
When front door RH is unlocked by front power window s witch (passenger side) (door lock and unlock switch),
BCM terminal 22 receives a signal from terminal 16 of front power window switch (passenger side) with power
window serial link.
When the hood is open, IPDM E/R receives a ground signal
to IPDM E/R terminal 56
through hood switch terminal 2
through hood switch terminal 1
through body grounds E21, E50 and E51.
The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM.
When the back door is open,
to BCM terminal 58
through back door closure motor terminal 7
through back door closure motor terminal 8
through body grounds B15 and B45.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
opening a door
opening the back door
opening the hood
detection of battery disconnect and connect.
The vehicle security system will be triggered once the system is in armed phase,
When BCM receives a ground signal at terminals 12 (p assenger side door), 13 (rear RH door), 58 (back door),
62 (driver side door), 63 (rear LH door), or rece ives a signal from the IPDM E/R (hood switch).
When the vehicle security system is triggered,
ground is supplied intermittently from IPDM E/R terminals 38 and 60.
