VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2007 April2007 M35/M45
POWER SUPPLY AND GROUND CIRCUIT
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. 21, located in the fuse block (J/B)]

to BCM terminal 42,

through 10A fuse [No. 71, located in the IPDM E/R]

to IPDM E/R internal CPU,

through 15A fuse [No. 78, located in the IPDM E/R]

to IPDM E/R internal CPU,

through 15A fuse [No. 37, located in the fuse block (J/B)]

to multi-function switch (security indicator) terminal 1.
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 M16 and M70.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and trunk.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and trunk are
closed and the doors are locked by key fob.
When a door is open, terminal 12 (passenger side door), 13 (rear RH door), 62 (driver side door), 63 (rear LH
door) 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 an unlock signal from terminal 14 of power window main switch with power window serial link.
When front door RH is unlocked by power window sub-switch (passenger side) (door lock and unlock switch),
BCM terminal 22 receives an unlock signal from terminal 16 of power window sub-switch (passenger side)
with power window serial link.
When front door key cylinder switch is in LOCK position, ground is supplied

to power window main switch terminal 4

through front door key cylinder switch terminals 6 and 4

through body grounds M16 and M70.
When the hood is open, IPDM E/R receives a ground signal

to IPDM E/R terminal 60

through hood switch terminal 2

through hood switch terminal 1

through body grounds E22, and E43.
The IPDM E/R then sends a signal to BCM via CAN communication line.
When the trunk is open, ground is supplied

to BCM terminal 57

through trunk room lamp switch terminal 1

through trunk room lamp switch terminal 2

through body grounds B402 and B405.

VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by

opening a door

opening the trunk

opening the hood

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 (passenger side door), 13 (rear RH door), 57 (trunk), 62
(driver side door), 63 (rear LH door), or receives a signal from the IPDM E/R (hood switch).
When the vehicle security system is triggered,
ground is supplied intermittently to both headlamp relay and horn relay.
When headlamp relay and horn relay are energized, 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.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the trunk must be unlocked with the key, Intelligent Key.
When the key is used to unlock a door, BCM terminal 22 receives signal

from the power window main switch (door lock and unlock switch) terminal 14.
When the BCM receives either one of these signals or unlock signal from key cylinder switch or Intelligent Key,
the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Intelligent Key system may or may not operate vehicle security system (horn and headlamps) as required.
When the Intelligent Key system is triggered, ground is supplied intermittently to both headlamp relay and horn
relay.
When headlamp relay and horn relay are energized, then power is supplied to headlamps (LH and RH) 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 Intelligent Key.
CAN Communication System DescriptionNIS001ZV
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 UnitNIS001ZW
