BCM is activated with low current consumption mode.
CAN communication is not active.
When CAN communication operation is detected, it switches to CAN communication status.
When a state of the following switches changes, it switches to CAN communication state:
–Ignition switch
–Key switch (insert)
–Hazard switch
–Main door lock/unlock switch
–Front door switch (LH, RH)
–Rear door switch (LH, RH)
–Back latch (door ajar switch)
–Glass hatch ajar switch
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Front door lock assembly LH (key cylinder switch)
When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
Status of combination switch reading function is changed.

REMOTE KEYLESS ENTRY SYSTEM
Revision: November 20092006 QX56
OPERATING PROCEDURE
When the keyfob is operated, the signal from the keyfob is sent and the remote keyless entry receiver
receives the signal and sends it to the BCM. The BCM only locks/unlocks the doors if the ID number
matches. (Remote control entry functions)
Using the keyfob, the transmitter sends radio waves to the remote keyless entry receiver, which then
sends the received waves to the BCM. Only if the ID number matches does the BCM lock/unlock the
doors. (Remote control door function)
Unless the key is inserted into the ignition key cylinder or one of the doors is opened within 1 minute after
the UNLOCK switch on the keyfob is pressed, all the doors are automatically locked. (Auto lock function)
When a door is locked or unlocked, the vehicle turn signal lamps flash and the horn sounds to verify oper-
ation. (Active check function)
When the key is in the ignition key cylinder (when the key switch is ON) and one of the doors is open, the
door lock function does not work even when the door lock is operated with the keyfob.
Keyfob ID set up is available.
If a keyfob is lost, a new keyfob can be set up. A maximum of 5 IDs can be set up simultaneously.
Remote Control Entry Functions
Operation Description
When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM sends the lock/unlock signal to each door lock actuator.
When the door lock actuators receive this signal, each operates to lock/unlock its door.
BCM locks all doors with input of LOCK signal from keyfob.
When an UNLOCK signal is sent from keyfob once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from keyfob again within 5 seconds, all other doors will be unlocked.
Remote control entry operation conditions
Auto Lock Function
Operation Description
Unless the key is inserted into the ignition key cylinder, one of the doors is opened, or the keyfob is oper-
ated within 1 minute after a door lock is unlocked by keyfob operation, all the doors are automatically
locked.
The 1 minute timer count is executed by the BCM and after 1 minute, the BCM sends the lock signal to all
doors.
Lock operations are the same as for the remote control entry function.
Remote Control Automatic Back Door Function
Switching from all closed to all open
When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM uses power window serial link communication to send the back door
open signal to the back door control unit
When the back door control unit receives the back door open signal for 0.5 seconds, if the remote control
automatic back door operation enable conditions are met, the warning chime is sounded and the back
door unlock signal is sent to the back door latch using communication.
When the back door latch receives the back door unlock signal, it operates the release actuator and
releases to back door latch.

The back door control unit operates the back door motor to open the back door. (At this time, speed con-
trol, input reverse, and overload reverse control are executed.)
When the back door is opened to the fully open position, the full-open position is detected with the rotation
sensor, the back door motor is stopped.
The door held by the back door stays at the full open position.
Full open → full closed operation
When a button of the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM uses power window serial link communication to send the back door
close request signal to the back door control unit.
When the back door control unit receives the back door close request signal for 0.5 seconds, if the remote
control automatic back door operation enable conditions are met, the warning chime is sounded and the
back door motor begins closing the back door.
The back door control unit operates the magnetic clutch and the back door motor to close the back door.
(At this time, the back door control unit executes speed control, input reverse, and overload reverse con-
trol.)
When the back door comes to the half-latch state, the back door latch detects the half-latch state through
half-latch switch operation. The back door latch latches the back door.
For the automatic back door system operation enable conditions, refer to BL-99, "
AUTOMATIC BACK DOOR
SYSTEM" .
Active Check Function
Operation Description
When a door is locked or unlocked by keyfob operation, the vehicle turn signals flash and the horn sounds to
verify operation.
When a button on the keyfob is operated, the signal is sent from the remote controller and received by the
keyless remote entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM sends the turn signal flashing and horn signal to the IPDM E/R.
The IPDM E/R flashes the turn signal lamps and sounds the horn for each keyfob operation.
Operating function of hazard and horn reminder
Hazard and Horn Reminder
BCM output to IPDM E/R for horn reminder signal as DATA LINE (CAN-H and CAN-L).
The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).
How to change hazard and horn reminder mode With CONSULT-II
Hazard and horn reminder can be changed using “WORK SUPPORT” mode in “MULTI ANSWER BACK SET".
Without CONSULT-II
Refer to Owner's Manual for instructions.
Interior Lamp Operation
When the following input signals are both supplied:
all door switches are in the OFF position. (when all the doors are closed);
interior lamp switch is in DOOR position.
Remote keyless entry system turns on interior lamp and ignition keyhole illumination (for 30 seconds) with
input of UNLOCK signal from keyfob.
For detailed description, refer to LT- 1 3 6 , "

ID Code Entry ProcedureEIS0060C
KEYFOB ID SET UP WITH CONSULT-II
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 controller 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.
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 codes are stored in memory when an additional code is registered, the
new ID code is added and no ID codes are erased.
Entry of a maximum of five ID codes is allowed. When more than five codes are entered, the oldest
ID code will be erased.
Even if the same ID code that is already in memory is input, the same ID code can be entered. The
code is counted as an additional code.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL) ”.
5. Touch “BCM”.
If "BCM" is not indicated, refer to GI-40, "
