BL-90
INTELLIGENT KEY SYSTEM
Revision: 2006 July 2007 FX35/FX45
accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door.

When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
OPERATION CONDITION
Door lock/unlock operation is necessary for all doors close.
Map Lamp And Keyhole Illumination Function
When the following conditions come:

condition of map lamp switch is DOOR position;

door switch OFF (when all the doors are closed);
Remote control button of Intelligent Key turns on interior lamp (for 30 seconds) with input of UNLOCK signal
from Intelligent Key.
Panic Alarm Function
When key switch is OFF and ignition knob is not pushed (when mechanical key is not inserted in ignition
knob), BCM turns ON and OFF horn and headlamp intermittently with input of PANIC ALARM signal from
Intelligent Key. The alarm automatically turns off after 25 seconds or when Intelligent Key unit receives any
signal from Intelligent Key.
Panic alarm operation mode can be changed using “WORK SUPPORT” mode in “PANIC ALARM DELAY”.
Refer to BL-116, "
WORK SUPPORT" .
Remote Control Power Window Down (Open) Operation
When Intelligent Key unlock switch is turned ON with ignition switch OFF, and Intelligent Key unlock switch is
detected to be on continuously for 3 seconds, the driver's door and passenger's door power windows are
simultaneously opened.
Power window is operated to open and the operation continues as long as the Intelligent Key unlock switch is
pressed.
Remote control power window down operation mode can be changed using “P/W DOWN DELAY” mode in
“WORK SUPPORT”. Refer to BL-116, "
WORK SUPPORT" .
Key Reminder Function
As an operation verification function, when doors are locked or unlocked using Intelligent Key remote control-
ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description

When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID
verification is conducted with Intelligent Key using two-way communication, and if verification is success-
ful, an ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit
releases ignition knob rotation prohibition latch. (Ignition knob can now be turned.)

When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights
up red.

When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses
CAN communication to send engine start permission signal to BCM.

When BCM receives engine start permission signal, it uses CAN communication to sent starter request
signal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the vehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.

Revision: 2006 July 2007 FX35/FX45
System CompositionNIS001PM
The immobilizer function of the IVIS (NATS) consists of the following:

Ignition key (models without Intelligent Key system)

Mechanical key (models with Intelligent Key system)

NATS antenna amp.

Steering lock unit. (models with Intelligent Key system)

BCM

Intelligent Key unit (models with Intelligent Key system)

Engine control module (ECM)

Security indicator
NOTE:
The communication between ECM, BCM and/or Intelligent Key unit uses the CAN communication sys-
tem.
ECM Re-Communicating FunctionNIS001PN
Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent
Key unit, but only when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)
NOTE:

When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS-IVIS/NVIS.

If multiple keys are attached to the key holder, separate them before work.

Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Using a registered key (*2), turn ignition switch to “ON”. *2: To perform this step, use the key that has been used before performing ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine. If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS-IVIS/NVIS and initialize control
unit.

FRONT DISC BRAKE
Revision: 2006 July 2007 FX35/FX45
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the specification. Refer to FA X - 4 , "
WHEEL
BEARING INSPECTION" (2WD models), FA X - 1 0 , "WHEEL
BEARING INSPECTION" (AWD models).
3. If runout is outside the limit, find the minimum runout point by shifting the mounting positions of disc rotor and wheel hub by
one hole.
4. If runout is still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equivalent).
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
Brake Burnishing ProcedureNFS000OD
Burnish brake pad contact surfaces of disc rotor according to following procedure after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:

Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.

Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Measurement point
: At a point 10.0 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.04 mm (0.0016 in) or less

Standard thickness : 34.0 mm (1.339 in)
Wear limit : 32.0 mm (1.260 in)

NOTE:
After removing/installing or replacing yaw rate/side/decel G sensor, ABS actuator and electric unit (control
unit), suspension components, or after adjusting wheel alignment, make sure to calibration of decel G sensor
before running vehicle.
CAUTION:
To calibrate decel G sensor, make sure to use CONSULT-II. (Adjustment can not be done without CON-
SULT-II.)
1. Stop vehicle with front wheels in straight-ahead position. CAUTION:

The work should be done at a horizontal place when vehicle is in the unloaded vehicle condi-
tion.

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure
value.
2. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
3. Touch “ABS”, “WORK SUPPORT” and “DECEL G-SEN CALIBRATION” on CONSULT-II screen in this order.
4. Touch “START”. CAUTION:
Set vehicle as shown in the display.
5. After approximately 10 seconds, touch “END”. (After approxi- mately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to perform above operation.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “DECEL G-SEN” on CONSULT-II screen. Then make sure “DECEL G-SEN” is within 0 ± 0.08 G. If value is
more than specification, repeat steps 3 to 7.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch OFF.
