●
through hood switch terminal 1
●
through body grounds E17, 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 lid lock assembly (trunk room lamp switch) terminal 1
●
through trunk lid lock assembly (trunk room lamp switch) terminal 2
●
through body grounds B402 and B413.
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), 57 (trunk), 62 (driver side 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 (with built-in IPDM E/R) and horn relay are energized, then power is supplied to head-
lamps (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, key fob.
When the key is used to unlock a door, BCM receives an unlock signal from terminal 22.
●
from the power window main switch (door lock and unlock switch) terminal 12.
When the BCM receives either one of these signals or unlock signal from key cylinder switch or key fob, the
vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote keyless entry system is triggered, ground is supplied intermittently to both headlamp relay
and horn relay.
When headlamp relay (with built-in IPDM E/R) and horn relay are energized, then power is supplied to head-
lamps (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 key fob.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
CAN Communication System Description
NIS001IQ
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.
