BACK DOOR OPENER OPERATION
NOTE:
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. Refer to DLK-9, "
ADDITIONAL SERVICE WHEN REMOVING
BATTERY NEGATIVE TERMINAL : Description".
The automatic back door system consists of a one piec e unit that combines the back door control unit along
with the back door motor, back door clutch and the ba ck door encoder. The back door latch contains a lock
function that can control the two functions of autom atic 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, if you press the power liftgat e switch or press the keyfob button, or pull the back
door handle with the back door unlocked, the back door latch motor drives the open the locking plate and
releases the latch. The back door motor t hen raises the door to the full open position.
With the back door fully open, if you 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 applic ation, the hazard lamps will flash 3 times and the
warning chime will sound 3 dings lasting a total of 2 seconds.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of back door open function
is in the range of approximately 80 cm (31.50 in) surrounding back
door opener request switch (1). However, this operating range
depends on the ambient conditions.

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.

• 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 shift selector (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
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

Power Liftgate Switch Operation (Fully Open → Fully Closed Operation)
• When the power liftgate switch is pressed, the ba ck door control unit terminal 23 receives the signal.
• The back door control units checks door position through the rotary encoder.
• When the back door control unit receives the signal, if the auto back door operating enable conditions are
