VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2006 July 2007 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.

Pull negative-pressure valve to open it, and make sure that it
close completely when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) and the radiator cap tester adapter (SST),
apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorNBS003JZ
Check radiator for mud or clogging. If necessary, clean radiator as follows.

Be careful not to bend or damage radiator fins.

When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan
assembly and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.

Use compressed air lower than 490 kPa (5 kg/cm2 , 71 psi) and keep distance more than 30 cm (11.81
in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
