REMOTE KEYLESS ENTRY SYSTEM
Revision: November 20092006 QX56
NOTE:

If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A specific ID
code can be erased with CONSULT-II. However, when the ID code of a lost keyfob is not known, all con-
troller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new
keyfobs must be re-registered.
To erase all ID codes in memory, register one ID code (keyfob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new keyfobs must be re-registered.

When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.

If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry ” for each new keyfob.

Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

AUTOMATIC BACK DOOR SYSTEM
Revision: November 20092006 QX56
System DescriptionEIS0060X
NOTE:
The automatic back door system must be initialized by fully closing the back door anytime the battery
or the back door control unit has been disconnected.
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, remote keyless entry 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 bat-
tery 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
terminal 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 bat-
tery 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
terminal 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.
