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, t he 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 s witch (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
 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 (p assenger side door), 13 (rear RH door), 58 (back door),
62 (driver side door), 63 (rear LH door), or rece ives 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.

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.
CAN Communication UnitINFOID:0000000001327907
Refer to LAN-43, "CAN System Specification Chart".

COMPASS
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 onl y 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 completed.
 Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.
 Turn off “non-essential” electrical accessories (r ear window defrost, heater/air conditioning, wipers) and
close the doors.
1. Verify the correct compass zone setting for the geographical location. Refer to DI-95, "
Zone Variation Set-
ting 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 in correct direction or the reading is erratic or locked,
repeat the calibration procedure.

The specification (SP) value indicates the tolerance of
the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT-III during normal operation of the Engine Control System. When the value in “SPEC”
of “DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the
value in “SPEC” of “DATA MONITOR” mode is NOT withi n the SP value, the Engine Control System may have
one or more malfunctions.
The SP value is used to detect malfunctions that may af fect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:
 B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc- tion)
 A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
