System Description

AIS001VP

DESCRIPTION
Operation Flow

Setting the Vehicle Security System

Initial condition

Ignition switch is in OFF position.

Disarmed phase

When doors or back door is open, the vehicle security system is set in the disarmed phase on the
assumption that the owner is inside or near the vehicle.

When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4
seconds.

Pre-armed phase and armed phase
When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”
phase. (The security indicator lamp illuminates.)

1.

BCM receives LOCK signal from front door key cylinder switch or key fob after, back door and all doors
are closed.

2.

Back door and all doors are closed after front doors are locked by key or door lock and unlock switch.
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 key fob.

2.

Turn ignition switch “ON” or “ACC” position.

Canceling the Alarm Operation of the Vehicle Security System

When unlocking the door with the key or key fob the alarm operation is canceled.

Activating the Alarm Operation of the Vehicle Security System

Make sure the system is in the armed phase. (The security indicator lamp blinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, the system sounds the horns and flashes the headlamps for
about 50 seconds.

1.

Back door or any door is opened during armed phase.

2.

Disconnecting and connecting the battery connector before canceling armed phase.

VEHICLE SECURITY (THEFT WARNING) SYSTEM

Revision: 2005 August

2005 Murano

POWER SUPPLY AND GROUND

Power is supplied at all times

through 10A fuse [No. 21, located in the fuse block (J/B)]

to combination meter (security indicator lamp) terminal 21.

Power is supplied at all times

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

to BCM terminal 55.

through 10A fuse [No. 18, located in the fuse block (J/B)]

to BCM terminal 42

When ignition switch is ACC or ON position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to BCM terminal 11.

Ground is supplied

to BCM terminal 52

through body grounds E13, E26 and M28.

INITIAL CONDITION TO ACTIVATE THE SYSTEM

The operation of the vehicle security system is controlled by the doors and back door.
To activate the vehicle security system, BCM must receive signals indicating the doors and back door are
closed and the doors are locked by key fob.
When a door is open, BCM terminals 12, 13, 62 or 63 receives a ground signal from each door switch.
When front door LH is unlocked by power window main switch (door lock and unlock switch), BCM terminal 22
receives a signal from terminal 14 of power window main switch.
When front door RH is unlocked by power window switch (passenger side) (door lock and unlock switch), BCM
terminal 22 receives a signal from terminal 16 of front power window switch (passenger side).
When front key cylinder switch is in UNLOCK position, ground is supplied

to power window main switch terminal 6

through front key cylinder terminals 6 and 5 (without Intelligent Key)

through door key cylinder switch terminals 3 and 2 (with Intelligent Key) 

through body grounds M14 and M78.

Then power window main switch send unlock signal to BCM.
When the back door is open, BCM terminal 58 receives a ground signal

through back door lock assembly terminal 3 and 4

through body grounds B7 and B20.

VEHICLE SECURITY SYSTEM ALARM OPERATION

The vehicle security system is triggered by

opening a door

opening the back door

detection of battery disconnect and connect.

The vehicle security system will be triggered once the system is in armed phase,
When BCM receives a ground signal at terminals 12, 13, 62 and 63 receives a signal from each door switch,
58 (back door switch).
Power is supplied at all times

to horn relay terminal 2

through 15A fuse (No. 32, located in the fuse and fusible link box).

When the vehicle security system is triggered, ground is supplied intermittently to both headlamp relay and
horn relay.
When headlamp high relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied
to headlamps (LH and RH) and horns (HIGH and LOW).
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.
