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.

KEYFOB ID SET UP WITHOUT 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 control-
ler ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new key-
fobs 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.

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.

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.
