VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 November2007 350Z
System DescriptionNIS0002T
DESCRIPTION
Operation Flow
Setting the vehicle security system
Initial condition
Ignition switch is in OFF position.
Disarmed phase
When hood, doors, back door (for Coupe) or trunk (for Roadster) 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 door key cylinder switch or key fob after all doors and back door (for
Coupe) or trunk (for Roadster) are closed.
2. All doors and back door (for Coupe) or trunk (for Roadster) are closed after 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. Open the back door (for Coupe) or trunk (for Roadster) with the key fob.
3. Turn ignition switch to “ON” or “ACC” position.
Canceling the alarm operation of the vehicle security system
When one of the following operations is performed, the alarm operation is canceled.
Unlock the door with the key or key fob.
Open the trunk (for Roadster) with the key fob.
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. Any door or trunk (for Roadster) is opened during armed phase.

2. Disconnecting and connecting the battery connector before canceling armed phase.
POWER SUPPLY AND GROUND
Power is supplied at all times
through 10A fuse [No.19, located in the fuse block (J/B)]
to security indicator lamp terminal 1.
Power is supplied at all times
through 40A 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.
With the ignition switch in the 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 M30 and M66.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors and trunk (for Roadster).
To activate the vehicle security system, BCM must receive signals indicating the doors and trunk (for Road-
ster) are closed and the doors are locked by key or key fob.
When a door is open, BCM terminals 12, 65 receives a ground signal from each door switch.
When driver side door is unlocked by power window main switch (door lock and unlock switch), BCM terminal
22 receives a signal from terminal 12 of power window main switch.
When passenger side door is unlocked by power window sub-switch (door lock and unlock switch), BCM ter-
minal 22 receives a signal from terminal 16 of power window sub-switch.
The IPDM E/R then sends a signal to the BCM via CAN communication line.
When the back door (for Coupe) or trunk (for Roadster) is open, BCM terminal 57 (for Roadster) or 58 (for
Coupe) receives a ground signal
from terminal 1 of the back door switch (for Coupe) or terminal 3 of trunk lid lock assembly (trunk room
lamp switch) (for Roadster)
through body grounds B5, B6,T14, D105 (for Coupe) or B5, B6, T14 (for Roadster).
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
opening a driver or passenger side door
opening the back door (for Coupe)
opening the trunk (for Roadster)
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, 62 (door switch), 57 (trunk room lamp switch) or 58 (back
door switch).
Power is supplied at all times
to horn relay terminal 2
through 15A fuse (No. 35, 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 both headlamp relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied
to headlamps (high beam and low beam) 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.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door must be unlocked or back door (for Coupe) or trunk (for
Roadster) must be opened with the key or key fob.
BL-128
VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 November2007 350Z
When the key is used to unlock a door, BCM terminal 22 receives signal
from terminal 12 of the power window main switch (door lock and unlock switch).
When the BCM receives either above signal or unlock signal from key fob, the vehicle security system is deac-
tivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the panic alarm button on the keyfob is triggered, ground is supplied intermittently to both headlamp
relay and horn relay.
When both headlamp relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied
to headlamps (high beam and low beam) and horns (HIGH and LOW).
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob.
CAN Communication System DescriptionNIS0002U
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS0002V
