through 10A fuse (No. 28, located in the fuse and fusible link box)

to horn relay terminal 2

through 15A fuse (No. 52, located in the IPDM E/R)

to IPDM E/R internal CPU.

through 20A fuse (No. 53, located in the IPDM E/R)

to IPDM E/R internal CPU.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 20, located in the fuse block (J/B)]

to BCM terminal 11.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to BCM terminal 38.
Ground is supplied

to BCM terminal 67

through body grounds M57 and M61.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors.
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
are closed and locked.
When a door is open, BCM terminal 12, 13, 43, 47 or 48 receives a ground signal from each door switch. In
addition to BCM, when back door is open, the Intelligent Key unit terminal 23 receives a ground signal from
back door through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by

opening a door

unlocking door without using the key, keyfob or Intelligent Key.
The vehicle security system will be triggered once the system is in armed phase,

when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), or terminal 43
(back door switch).
When the vehicle security system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to horn relay terminal 1.
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 must be unlocked with the key, keyfob or Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal

from terminal 3 of the front door key cylinder switch LH.
When the BCM receives this signal or unlock signal from keyfob or Intelligent Key or front door key cylinder
switch LH, the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Intelligent Key and 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

from IPDM E/R terminal 45

to horn relay terminal 1.
The headlamp flashes and the horn sounds intermittently.
