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, "
CONSULT-II Data Link
Connector (DLC) Circuit" .

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: November 20092006 QX56
System DescriptionEIS0060F
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition

Ignition switch is in OFF position.
Disarmed phase

When the vehicle is being driven or when doors or glass hatch is open, the vehicle security system is set
in the disarmed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase

The vehicle security system turns into the "pre-armed" phase when hood, glass hatch and all doors are
closed and locked by keyfob. The security indicator lamp illuminates for 30 seconds, then the system
automatically 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.

2. Door is unlocked without using key or keyfob.
3. Power back door is opened without using the keyfob.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No.19, located in the fuse block (J/B)]

to combination meter (security indicator lamp) terminal 8 and

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70

through 15A fuse [No. 22, located in the fuse block (J/B)]

to BCM terminal 57

through 15A fuse (No. 25, located in the fuse and fusible link box)

to horn relay terminal 2

through 20A fuse (No. 52, located in the IPDM E/R) and

through 20A fuse (No. 53, located in the IPDM E/R),

to IPDM E/R internal CPU.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 4, located in the fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 67

through body grounds M57, M61 and M79 and

to IPDM E/R terminals 38 and 59

through body ground E9, E15 and E24.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and glass hatch.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and glass hatch
are closed and the doors are locked.
When a door is open, BCM terminal 12, 13, 42, 47 or 48 receives a ground signal from each door switch.
When front door LH is unlocked, BCM terminal 22 receives a signal from terminal 14 of main power window
and door lock/unlock switch.
When front door RH is unlocked, BCM terminal 22 receives a signal from terminal 16 of power window and
door lock/unlock switch RH or the rear power window switch LH or RH.
When the back door is open, BCM terminal 43 receives a ground signal

from terminal 7 of the back door latch (door ajar switch)

through body grounds B7 and B19.
When the glass hatch is open, BCM terminal 42 receives a ground signal

from terminal + of the glass hatch ajar switch

through glass hatch ajar switch case ground.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by

opening a door

opening the hood

opening the glass hatch

unlocking door without using the key or keyfob.
The vehicle security system will be triggered once the system is in armed phase,

when BCM receives a ground signal at terminals 12, 13, 47, 48 (door switch), terminal 42 (glass hatch ajar
switch) or terminal 43 [back door latch (door ajar switch)], or IPDM E/R terminal 41 (hood switch) receives
a ground signal.
Power is supplied at all times

to horn relay terminal 2
