VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: August 20072004 QX56
System DescriptionEIS002SE
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition
Ignition switch is in OFF position.
Disarmed phase
When the vehicle is being driven or when doors or glass hatch is open, the vehicle security system is set
in the disarmed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase
There are three conditions to enable the vehicle security system to turn into the "pre-armed" phase and
transition into armed phase. The initial requirements are that hood, glass hatch and all doors must be
closed (ignition key removed) for the transition to take place. Those three conditions are:
1. Locking vehicle with either front power door lock switch before exiting vehicle and closing all doors.
2. Using keyfob to lock already closed doors after leaving the vehicle.
3. Using driver key cylinder switch to lock already closed doors after leaving the vehicle.
Upon any of the above three steps taking place, the security indicator lamp illuminates for 30 seconds,
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 or the keyfob.
2. Open the power back door with the keyfob. When the power back door is closed after opening the power
back door with the keyfob, the system returns to the armed phase.
Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the headlamps
for about 50 seconds.
1. Engine hood, glass hatch or any door is opened before unlocking door with key or keyfob.
2. Door is unlocked without using key or keyfob.
3. Power back door is opened without using the keyfob.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 4, located in the fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminal 67
through body grounds M57, M61 and M79 and
to IPDM E/R terminals 38 and 59

INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and glass hatch.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and glass hatch
are closed and the doors are locked.
When a door or glass hatch is open, BCM terminal 12, 13, 42, 43, 47 or 48 receives a ground signal from that
switch. When the hood is open, IPDM E/R terminal 41 receives a ground signal from the hood switch.
When the front door switch LH is ON (door is open), ground is supplied
to BCM terminal 47
through front door switch LH terminal 2
through front door switch LH case ground.
When the front door switch RH is ON (door is open), ground is supplied
to BCM terminal 12
through front door switch RH terminal 2
through front door switch RH case ground.
When the rear door switch LH is ON (door is open), ground is supplied
to BCM terminal 48
through rear door switch LH terminal 2
through rear door switch LH case ground.
When the rear door switch RH is ON (door is open), ground is supplied
to BCM terminal 13
through rear door switch RH terminal 2
through rear door switch RH case ground.
When the back door latch (door ajar switch) is ON (door is open), ground is supplied
to BCM terminal 43
through back door latch (door ajar switch) terminal 7
through back door latch (door ajar switch) terminal 8
through grounds B7 and B19.
When the glass hatch ajar switch is ON (hatch is open) ground is supplied
to BCM terminal 42

VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
opening a door
opening the hood
opening the glass hatch
unlocking door without using the key or keyfob.
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 (door switch), terminal 42 (glass hatch ajar
switch) or terminal 43 [back door latch (door ajar switch)], or IPDM E/R terminal 41 (hood switch) receives
a ground signal.
Power is supplied at all times
to horn relay terminal 2
through 15A fuse (No. 25, located in fuse and fusible link box).
When the vehicle security system is triggered, ground is supplied intermittently
from IPDM E/R terminal 45
to headlamp high relay and
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 must be unlocked with the key or keyfob.
When the key is used to unlock the front door LH, BCM terminal 22 receives signal
from terminal 14 of the main power window and door lock/unlock switch.
When the BCM receives this signal or unlock signal from keyfob, the vehicle security system is deactivated.
(Disarmed phase)
PANIC ALARM OPERATION
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
from IPDM E/R terminal 45
to headlamp high relay and
to horn relay terminal 1.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.
