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
• The vehicle security system turns into the "pre-armed" phase when hood, glass hatch and all doors are
closed and locked by keyfob. The security indicator lamp illuminates for 30 seconds, then the system auto-
matically 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.

Ground is supplied
• to BCM terminal 67
• through body grounds M57, M61 and M79 and
• to IPDM E/R terminals 38 and 59
• through body ground E9, E15 and E24.
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 is open, BCM terminal 12, 13, 42, 47 or 48 receives a ground signal from each door switch.
When front door LH is unlocked, BCM terminal 22 receives a signal from terminal 14 of main power window
and door lock/unlock switch.
When front door RH is unlocked, BCM terminal 22 receives a signal from terminal 16 of power window and
door lock/unlock switch RH or the rear power window switch LH or RH.
When the back door is open, BCM terminal 43 receives a ground signal
• from terminal 7 of the back door latch (door ajar switch)
• through body grounds B7 and B19.
When the glass hatch is open, BCM terminal 42 receives a ground signal
• from terminal + of the glass hatch ajar switch
• through glass hatch ajar switch case ground.
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.
