VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 January2006 M35/M45
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.
