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.
Activating the Alarm Operation of the Vehicle Security System
Make sure the system is in the armed phase. (The security indicator lamp brinks 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.19, located in the fuse block (J/B)]

to security indicator lamp terminal 1.

through 50A fusible link (letter M , located in the fuse and fusible link box)

to BCM terminal 55.

through 15A fuse [No.22, located in the fuse block (J/B)]

to BCM terminal 42.

through 15A fuse [No.34, located in the fuse and fusible link box]

to horn relay terminal 2.

through 10A fuse [No.71, located in the IPDM E/R]

to IPDM E/R internal CPU.

through 15A fuse [No.78, 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. 6, located in the fuse block (J/B)]

to BCM terminal 11.
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, Intelligent Key or ignition key.
When a door is open, BCM terminal 12 (passenger side door), 13 (rear RH door), 62 (driver side door), 63
(rear LH door) receives a ground signal from each door switch.
When front door LH is unlocked by power window main switch (door lock and unlock switch),
BCM terminal 22 receives a signal from terminal 14 of power window main switch with power window serial
link.
When front door RH is unlocked by front power window switch (passenger side) (door lock and unlock switch),
BCM terminal 22 receives a signal from terminal 16 of front power window switch (passenger side) with power
window serial link.
When the hood is open, IPDM E/R receives a ground signal

to IPDM E/R terminal 56

through hood switch terminal 2

through hood switch terminal 1

through body grounds E21, E50 and E51.
The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM.
When the back door is open,

to BCM terminal 58

through back door closure motor terminal 7

BL-190
VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2005 July 2005 FX

through back door closure motor terminal 8

through body grounds B15 and B45.
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 12 (passenger side door), 13 (rear RH door), 58 (back door),
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 from IPDM E/R terminals 38 and 60.
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 main switch (door lock and unlock switch).
When the BCM receives either one of these signals or unlock signal from key cylinder switch, key fob or Intel-
ligent Key, 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 from IPDM E/R terminals
38 and 60.
When headlamp relay (which 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 25 seconds or when BCM receives any signal from key fob or Intelligent
Key.

COMPASS
Revision: 2005 July 2005 FX
COMPASSPFP:24835
System DescriptionAKS007AO
This unit displays earth magnetism and heading direction of vehicle.
DIRECTION DISPLAY
Push the switch when the ignition key is in the “ON” or “START” position. The direction will be displayed.
Pushing the “COMP” switch a second time will turn off the display.
1. If the display reads “C” calibrate the compass by driving the vehicle in 3 complete circles at less than 8 km/h (5 MPH).
2. To adjust for compass variance:
a. Press the “COMP” switch for more than 3 seconds. The current zone number will appear in the display.
b. Find your current location and variance zone number on the zone map.
c. Press the “COMP” switch until the new zone number appears in the display. After you stop pressing the button in, the display will show a compass direction within a few seconds.
NOTE:
1. Do not install the ski rack, antenna, etc. which are attached to the vehicle by means of a magnet. They affect the operation of the compass.
2. If the compass deviates from the correct indication soon after repeated adjustment, have the compass checked at an authorized dealer.
3. The compass may not indicate the correct compass point in tunnels or while driving up or down a steep hill. (The compass returns to the correct compass point when the vehicle moves to an area where the
geomagnetism is stabilized.)
3. Cleaning the Mirror When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not
spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.
“C” is displayed in the compass window.

The compass needs to be calibrated. Drive the vehicle in 3 circles at
8 km/h (5 MPH) or less until the display reads a direction. You can
also calibrate the compass by driving your vehicle on your everyday
routine. The compass will be calibrated once it has tracked 3 com-
plete circles.
Inaccurate Compass Direction
1. With the display turned on, push the “COMP” switch for 3 seconds, until the zone selection comes up (a
number will be displayed in the mirror compass window).
2. Toggle until correct zone is found and release switch.
3. The display will show all segments, and return to the normal compass mode within 10 seconds of no switch activity.
4. If the vehicle changes zone, repeat steps 1 through 3. See map.
