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-184
VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 December 2006 FX35/FX45

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.
CAN Communication System DescriptionNIS001P4
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.
CAN Communication UnitNIS001P5
Refer to LAN-27, "CAN COMMUNICATION" .

Zone Variation Setting ProcedureNKS003HT
NOTE:
The zone setting is factory preset (“default” setting) to zone 8.
1. Press and hold the inside mirror switch for 6 – 9 seconds.
2. The current zone setting appears on the compass display.
3. Find the current geographical location number in the Zone Varia- tion Chart.
4. Select the new zone number. (Press the inside mirror switch until the new zone number appears on the compass display.)
5. After select the new zone number, the compass display will automatically shows a direction within a few seconds.
6. Preform the following Calibration Procedure for more accurate indications.
Calibration ProcedureNKS003HU
NOTE:
The compass calibrates itself under normal driving conditions. However, occasional circumstances may cause
the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or
if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Cali-
brate the mirror compass if the display shows only one direction or a limited number of directions.
NOTE:

If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle
before performing the following steps. Do NOT put the hat back on the vehicle after the procedure is com-
pleted.

Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.

Turn off “non-essential” electrical accessories (rear window defrost, heater/air conditioning, wipers) and
close the doors.
1. Verify the correct compass zone setting for the geographical location. Refer to D I - 111 , "
Zone Variation
Setting Procedure" .
2. Press and hold the inside mirror switch for more than 9 seconds.
3. “C” is displayed on the compass display, when calibration starts.
4. Drive slowly [less than 8 km/h (5 mph)] in a circle until the “C / CAL” is replaced with primary headings (N, NE, E, SE, S, SW, W, or NW).
NOTE:
This will require driving at least 2 complete 360 degree circles; 3 complete circles may be required.
5. The compass calibration procedure is now complete. The compass should operate normally.
NOTE:
If at any time the compass continually displays the incorrect direction or the reading is erratic or locked,
repeat the calibration procedure.
