When unlocking the door with the key or key fob the alarm operation is canceled.
Activating the Alarm Operation of the Vehicle Security System
Make sure the system is in the armed phase. (The security indicator lamp blinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, the system sounds the horns and flashes the headlamps for
about 50 seconds.
1.
Hood, back door or any door is opened during armed phase.
2.
Disconnecting and connecting the battery connector before canceling armed phase.
POWER SUPPLY
Power is supplied at all times
●
through 10A fuse [No. 21, located in the fuse block (J/B)]
●
to combination meter (security indicator lamp) terminal 21.
Power is supplied at all times
●
through 50A fusible link (letter F , located in the fuse and fusible link box)
●
to BCM terminal 7.
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 36.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and back door.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and back door
are closed and the doors are locked by key fob.
When a door is open, BCM terminal 10 or 14 receives a ground signal from each door switch. (Auxiliary cir-
cuit.)
When a door is open, unified meter and A/C amp. terminal 7 (passenger side door), 8 (driver side door), 17
(rear RH door), 18 (rear LH door) receives a ground signal from each door switch.
The unified meter and A/C amp. then sends a signal to the BCM through the CAN SYSTEM.
When front door LH is unlocked by power window main switch (door lock and unlock switch), BCM terminal 74
receives a signal from terminal 14 of power window main switch.
When front door RH is unlocked by power window switch (passenger side) (door lock and unlock switch), BCM
terminal 74 receives a signal from terminal 16 of front power window switch (passenger side).
When the hood is open, IPDM E/R receives a ground signal
●
from hood switch terminal 1
●
to IPDM E/R terminal 51
●
through body grounds E13, E26 and E28.
The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM.
When the back door is open, BCM terminal 18 receives a ground signal
●
from terminal 1 of the back door switch
●
through body grounds B7 and B20.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
●
opening a door
●
opening the back door
●
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 10, 14 receives a signal from the unified meter and A/C amp.
(door switch), 18 (back door switch) or receives a signal from the IPDM E/R (hood switch).
Power is supplied at all times
●
to horn relay terminal 2
●
through 10A fuse (No. 32, located in fuse and fusible link box).

When the vehicle security system is triggered, ground is supplied intermittently from IPDM E/R terminals 14
and 45.
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 or key fob.
When the key is used to unlock a door, BCM terminal 74 receives signal
●
from terminal 14 of the power window main switch (door lock and unlock switch).
When the BCM receives either one of these signals or unlock signal from key fob or key cylinder switch, the
vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote control entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote control entry system is triggered, ground is supplied intermittently from IPDM E/R terminals
14 and 45.
When headlamp 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 headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds or when BCM receives any signal from key fob.
CAN Communication System Description
AIS001VQ
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.
