VEHICLE SECURITY (THEFT WARNING) SYSTEM
System Description
INFOID:0000000001327905
DESCRIPTION
Operation Flow
Setting the Vehicle Security System
Initial condition
 Ignition switch is in OFF position.
Disarmed phase
 When hood, doors or back door is open, the vehicle secu rity 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 sec-
onds.
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 front door key cyli nder switch, key fob or Intelligent Key after hood, back
door and all doors are closed.
2. Hood, back door and all doors are closed after front doors are locked by key or door lock and unlock
switch.
The security indicator lamp illuminates for 30 sec onds. 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, key fob or Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.
Canceling the Alarm Operation of the Vehicle Security System
When unlock the door with the key, key fob or Intelligent Key the alarm operation is canceled.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
When headlamp high relay (with built-in IPDM E/R) and horn relay are energized and 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 back door must be unlocked with the key, key fob or
Intelligent Key.
When the key is used to unlock a door, BCM terminal 22 receives signal
 from terminal 14 of the power window ma in switch (door lock and unlock switch).
When the BCM receives either one of these signals or unl ock signal from key cylinder switch, key fob or Intel-
ligent Key, the vehicle security sy stem is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operat e vehicle security system (horn and headlamps) as
required.
When the remote keyless entry system is triggered, ground is supplied intermittently from IPDM E/R terminals
38 and 60.
When headlamp relay (which built-in IPDM E/R) and hor n relay are energized and then power is supplied to
headlamps (LH and RH) and horns (HIGH and LOW).
The headlamp flashes and the hor n sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob or Intelligent
Key.
CAN Communication System DescriptionINFOID:0000000001327906
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 s peed 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 CA N 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.
