• to BCM terminal 43
• through back door latch (door ajar switch) terminal 7,
• through back door latch (door ajar switch) terminal 8,
• through body grounds B7 and B19.
Keyfob signal is input into the BCM from the remote keyless entry receiver.
The remote keyless entry system controls operation of the
• power door lock
• back door opener
• interior lamp and step lamps
• panic alarm
• hazard and horn reminder
• keyless power window down (open)
• auto door lock operation
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 opera-
tion. (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.

ID Code Entry ProcedureINFOID:0000000003532936
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 spe-
cific 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)”.Map lamp and ignition keyhole illumination should illuminate.
