1. Remove the door finisher. Refer to EI-33, "Removal and Installation" .
2. Remove the door window and door module assembly. Refer to GW-51, "
Removal and Installation" .
EXTERIOR HANDLE ROD ADJUSTMENT
Rotate the bushing to adjust so that the clearance between the bush-
ing and rod becomes as shown in the figure.
CAUTION:
Be careful not to make the clearance 0 mm (0 in) or the rod will
be pressed continuously.

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.

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
Refer to LAN-4, "CAN Communication System" .
