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
• 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.

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
• 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.

The automatic back door system must be initialized by fully closing the back door anytime the battery
power is lost to the back door control unit.
The automatic back door system consists of a one piece unit that combines the back door control unit along
with the back door motor, back door clutch and the back door encoder. The back door latch contains a lock
function that can control the two functions of automatic back door latch closure and electrical opener with a
single motor when you close the back door to the halfway-state.
• Back door auto closure
When the back door is closed to the halfway state (half-latch) position, the motor automatically drives to
rotate the latch lever and pull it in from half latched to full latched.
• Power back door
With the back door closed, press the power liftgate switch or press the keyfob button, or pull the back door
handle with the back door unlocked, the back door latch motor opens the locking plate and releases the
latch. The back door motor then raises the door to the full open position.
With the back door fully open, press the power liftgate switch, keyfob button or the back door close switch,
the back door motor closes the door to the half-latch state. The back door latch motor then drives the latch to
the full close position.
At the onset of each power open or power close application, the hazard lamps will flash 3 times and the
warning chime will sound 3 times lasting a total of 2 seconds.
OPERATION DESCRIPTION
Power Liftgate Switch Operation (Fully Closed → Fully Open Operation)
• When the power liftgate switch is pressed, back door control unit terminal 23 receives the signal.
• The back door control unit checks the A/T selector lever (P position) through terminal 18, vehicle speed
through terminal 21, ignition status through terminal 7, glass hatch is closed through terminal 17 and battery
voltage is present through terminal 3.
• When the back door control unit receives the signal, if the auto back door operating enable conditions are
met, it sends a 5 volt signal through terminal 6 and grounds terminal 9 to sound the warning chime, sends a
signal to the BCM through terminal 4 to flash the hazard lamps and unlocks the back door latch through ter-
minal 12.
• The back door control unit supplies power to the magnetic clutch and the back door motor and moves the
back door in the open direction. (At this time, it also executes speed control, input reverse, and anti-pinch
detection control.)
• When the back door is opened to the full-open position, the full-open position is detected by the encoder,
and the back door control unit switches the back door motor OFF and the magnetic clutch is pulsed and then
turned OFF.
• The back door is held in the fully open position by the gas stays.
Remote Keyless Entry Operation (Fully Closed → Fully Open Operation)
• When the keyfob button is pressed for at least 0.5 seconds, back door control unit terminal 21 receives the
signal.
• The back door control unit checks the A/T selector lever (P position) through terminal 18, vehicle speed
through terminal 21, ignition status through terminal 7, glass hatch is closed through terminal 17 and battery
voltage is present through terminal 3.
• When the back door control unit receives the signal, if the auto back door operating enable conditions are
met, it sends a 5 volt signal through terminal 6 and grounds terminal 9 to sound the warning chime, sends a
signal to the BCM through terminal 4 to flash the hazard lamps and unlocks the back door latch through ter-
minal 12.
• The back door control unit supplies power to the magnetic clutch and the back door motor and moves the
back door in the open direction. (At this time, it also executes speed control, input reverse, and anti-pinch
detection control.)
• When the back door is opened to the full-open position, the full-open position is detected by the encoder,
and the back door control unit switches the back door motor OFF and the magnetic clutch is pulsed and then
turned OFF.
• The back door is held in the fully open position by the gas stays.
Back Door Handle Switch Operation (Fully Closed → Fully Open Operation)
• When the back door handle is pulled, back door control unit terminal 26 receives the signal.
• The back door control unit checks that the back door is unlocked and checks the A/T selector lever (P posi-
tion) through terminal 18, vehicle speed through terminal 21, ignition status through terminal 7, glass hatch is
closed, battery voltage and back door close switch position through terminal 13.
• When the back door control unit receives the signal, if all auto back door operating enable conditions are
met, it sends a 5 volt signal through terminal 6 and grounds terminal 9 to sound the warning chime, sends a
