ID Code Entry ProcedureEIS008QJ
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-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .

6. Touch “MULTI REMOTE ENT”.
7. Touch “WORK SUPPORT”.
8. The items are shown on the figure can be set up.

“REMO CONT ID REGIST”
Use this mode to register a keyfob ID code.
NOTE:
Register the ID code when keyfob or BCM is replaced, or
when additional keyfob is required.

“REMO CONT ID ERASUR”
Use this mode to erase a keyfob ID code.

“REMO CONT ID CONFIR”
Use this mode to confirm if a keyfob ID code is registered or
not.

REMOTE KEYLESS ENTRY SYSTEM
Revision: October 20052005 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.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: October 20052005 QX56

to horn relay terminal 2

through 15A fuse (No. 25, located in fuse and fusible link box).
When the vehicle security system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to headlamp high relay and

to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door must be unlocked with the key or keyfob.
When the key is used to unlock the front door LH, BCM terminal 22 receives signal

from terminal 14 of the main power window and door lock/unlock switch.
When the BCM receives this signal or unlock signal from keyfob, the vehicle security system is deactivated.
(Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote keyless entry system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to headlamp high relay and

to horn relay terminal 1.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.
