LASER BEAM AIMING ADJUSTMENTPFP:00026
OutlineNKS004CM
Adjust the laser beam aiming every time the ICC sensor integrated unit is removed or installed.
CAUTION:

Adjust laser beam aiming at a horizontal place as far as 12 m (39 ft) forward the vehicle can be
seen.

Adjust laser beam aiming 5 seconds after starting engine.

Never view ICC sensor integrated unit body window directly during laser beam aiming adjustment.

Follow the CONSULT-II when adjusting the laser beam aiming (laser beam aiming adjustment can-
not be operated without CONSULT-II).

Never ride on vehicle during laser beam aiming adjustment.

Idle and turn headlamps OFF during laser beam aiming adjustment.
PreparationNKS004CN

Adjust the tire pressure to the specified value.

See that there is no load in the vehicle.

Coolant, engine oil filled up to correct level and full fuel tank.

Shift the gear into “P” position and release the parking brake.

Clean the ICC sensor integrated unit with a soft cloth.

Remove the front bumper grille. Refer to EI-13, "Removal and
Installation of Front Bumper Grille" .
Outline of Adjustment ProcedureNKS004CO
1. Set up the ICC target board [KV99110100 (J-45718)].
2. Adjust the sensor following the procedure on CONSULT-II. (Turn manually the screw for up-down position
adjustment. ICC sensor integrated unit automatically adjust the right-left position.)
Setting the ICC Target BoardNKS004CP
Accurate ICC target board setting is required for the laser beam aiming adjustment.
CAUTION:
ICC system does not function normally if laser beam aiming is not accurate.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale at 28 mm (1.10 in) below the center.

BCM (BODY CONTROL MODULE)
Revision: 2007 April2007 M35/M45
Operation Table of BCM and Combination Switches
BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp system has a dual switch.
Sample Operation:

When lighting switch 1ST position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.

When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that lighting
switch 1ST position is ON. Then BCM sends tail lamp and clearance lamp request signal to IPDM E/R
using CAN communication.

When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and recog-
nizes that lighting switch 1ST position is continuously ON.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.

HOOD
Revision: 2007 April2007 M35/M45
1. Check the clearance and the surface height between the hood and each part by visual and tactile feeling.
(Fitting standard dimension in the table below should be satisfied.)
* Unit: mm (in)
2. In case out of specification, adjust them according to the procedures shown below.
3. Remove the hood lock and adjust the height by rotating the
bumper rubber until the hood becomes 1 to1.5 mm (0.04 to
0.059 in) lower than the fender.
4. Temporarily tighten the hood lock, and position by engaging it with the hood striker. Check the lock and
striker for looseness and adjust the clearance and evenness by the striker to satisfy the specification.
5. Adjust A and B shown in the figure to the following value with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height or the hood pressed lightly (approx. 29 N (3 kg)).
6. After adjustment tighten lock bolts to the specified torque.
1. Hood hinge 2. Hood lock assembly 3. Hood assembly
4. Hood top molding 5. Bumper fascia assembly 6. Headlamp

INTELLIGENT KEY SYSTEM
Revision: 2007 April2007 M35/M45
Hazard and Horn Reminder Function
When doors are locked or unlocked by Intelligent Key, Intelligent Key unit sends hazard and horn request sig-
nal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and sends horn chirp signal to IPDM E/R. IPDM E/R
sounds horn as a reminder.
The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).
Operating function of hazard and horn reminder
Hazard and horn reminder does not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-II
Hazard and horn reminder can be changed using “HORN WITH KEYLESS LOCK” and “HAZARD ANSWER
BACK” mode in “WORK SUPPORT”.Refer to BL-81, "
WORK SUPPORT" .
Without CONSULT-II
When LOCK and UNLOCK signals are sent from the Intelligent Key for more than 2 seconds at the same time,
the hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intel-
ligent Key is not inserted in key slot), doors are unlocked with Intelligent Key button. When Intelligent Key unit
does not receive the following signals within 30 seconds, all doors are locked.

Door switch is ON (door is opened)

Door is locked

Ignition switch is ON

Key switch is ON (Intelligent Key is inserted in key slot)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
81, "WORK SUPPORT" .
Panic Alarm Function
When ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intelligent Key is not
inserted in key slot), Intelligent Key unit receives PANIC ALARM signal from Intelligent Key.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM turns on and off headlamp intermittently and sends theft warning horn signal to IPDM E/R. Then, IPDM
E/R turns on and off horn intermittently.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:

After 25 seconds

When Intelligent Key unit receives any signal from Intelligent Key

When door request switch is pressed (Intelligent Key is within the outside key antenna detection area)
Panic alarm function mode can be changed by “PANIC ALARM DELAY” mode in “WORK SUPPORT”. Refer to
BL-81, "
WORK SUPPORT" .
