LASER BEAM AIMING ADJUSTMENT
LASER BEAM AIMING ADJUSTMENT
DescriptionINFOID:0000000006224293
OUTLINE OF LASER BEAM AIMING ADJUSTMENT
Always adjust the laser beam aiming after removing and installing or replacing the ICC sensor.
CAUTION:
The system does not operate normally
unless the laser beam aiming adjustment is performed. Always
perform it.
1. Set the ICC target board [SST: KV99110100 (J-45718)] to the correct position in front of the vehicle.
2. Set the laser beam aiming mode (“LASER BEAM AD JUST” on “Work support”) with CONSULT-III, and
then perform the adjustment according to the displa y. (Manually turn the up-down direction adjusting
screw for vertical adjustment. ICC sensor adjusts the automatic aiming for the horizontal direction.)
CAUTIONARY POINT FOR LASER BEAM AIMING ADJUSTMENT
CAUTION:
For laser beam aiming adjustment, choose a level location where a view can be obtained without any
obstruction as far as 12 m (39 ft) or more in the forward direction.
Adjust laser beam aiming for 5 second s or more after starting engine.
Adjust the laser beam aiming with CONSULT-III. (The laser beam aiming cannot be adjusted without
CONSULT-III.)
Never enter the vehicle during laser beam aiming adjustment.
Never look directly into the laser beam sour ce (ICC sensor body window) during laser beam aiming
adjustment.
Laser beam aiming adjustment is performed at idle. At this time, turn the headlamps OFF.
Work Procedure (Preparation)INFOID:0000000006224294
1.ADVANCE PREPARATION FOR LASER BEAM AIMING ADJUSTMENT
1. Adjust all tire pressure to the specified value.
2. Empty the vehicle. (Remove any luggage from the passenger compartment, luggage room, etc.)
3. Shift the selector lever to “P” pos ition, and release the parking brake.
4. Fully fill the fuel tank, and then check that t he coolant and oils are filled up to correct level.
5. Clean off the ICC sensor body window with a soft cloth.
>> Go to CCS-72, "
Work Procedure (Setting The ICC Tar-
get Board)".
Work Procedure (Setting The ICC Target Board)INFOID:0000000006224295
DESCRIPTION
Accurate adjustment of the laser beam requires t hat the ICC target board be accurately positioned.
CAUTION:
If the laser beam is adjusted with the ICC target board in the incorrect position, the ICC system does
not function normally.

is selected, the following causes are possible.
The ICC target board is not installed in the correct position.
Adequate space is not secured around the ICC target board.
The laser beam aiming adjustment exceeds its proper installation range.
- Deformation of vehicle body.
- Deformation of unit.
- Deformation of bracket.
The area is not suitable for the adjustment work.
ICC sensor body window is not clean.
The ICC system warning lamp illuminates.

CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communicati on speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control units , 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, CAN-L) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.
CAN communication signal chart. Refer to LAN-28, "
CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
ITS COMMUNICATION
ITS communication is a multiplex communication syste m. This enables the system to transmit and receive
large quantities of data at high speed by connec ting control units with 2 communication lines.
ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.

PRECAUTIONS FOR VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
ICC system is only an aid to assist the driver and is not a collision warning or avoidance device. It is the\
driver's responsibility to stay alert, drive safe ly and be in control of the vehicle at all times.
The system is primarily intended for use on straight, dry, open roads with light traffic. It is not advisable to
use the system in city traffic or congested areas.
This system will not adapt automatically to road condi tions. This system should be used in evenly flowing
traffic. Do not use the system on roads with sharp curves, or on icy roads, in heavy rain or in fog.
The ICC sensor will not detect under most conditions.
- Stationary and slow moving vehicles.
- Pedestrians or objects in the roadway.
- Oncoming vehicles in the some lane.
- Motorcycles traveling offset in the travel lane.
As there is a performance limit to the distance contro l function, never rely solely on the ICC system. This
system does not correct careless, inattentive or absent -minded driving, or overcome poor visibility in rain,
fog, or other bad weather. Decelerate the vehicle speed by depressing the brake pedal, depending on the
distance to the vehicle ahead and the surrounding circumstances in order to maintain a safe distance
between vehicles.
If the vehicle ahead comes to a stop, the vehicle decelerat es to a standstill within the limitations of the sys-
tem. The system will cancel once it judges that the vehicle has come to a standstill and sound a warning
chime. To prevent the vehicle from movi ng, the driver must depress the brake pedal.
The system may not detect the vehicle in front of the dr iver in certain road or weather conditions. To avoid
accidents, never use the ICC syst em under the following conditions:
- On roads where the traffic is heavy or there are sharp curves.
- On slippery road surfaces such as on ice or snow, etc.
- On off-road surfaces such as on sand or rock, etc.
- During bad weather (rain, fog, snow, etc.)
- When the windshield wipers are operating at high speed. The ICC system may cancel when the wipers are
set to the AUTO position.
- When strong light (for example, at sunrise or sunset ) is directly shining on the front of the vehicle.
- When rain, snow or dirt adhere to the system sensor.
- On steep downhill roads (the vehicle may go beyond the set vehicle speed and frequent braking may result
in overheating the brakes).
- On repeated uphill and downhill roads.
- When traffic conditions make it difficult to keep a proper distance between vehicles because of frequent
acceleration or deceleration.
- When towing a trailer or other vehicle
In some road or traffic conditions, a vehicle or object can unexpectedly come into the sensor detection zone
and cause automatic braking. The driver may need to c ontrol the distance from other vehicles using the
accelerator pedal. Always stay alert and avoid using t he ICC system when it is not recommended in this sec-
tion.
The vehicle-to-vehicle distance control mode uses a sensor located on the front of the vehicle to detect vehi-
cles traveling ahead. The sensor generally detects t he signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor c annot detect the reflector on the v ehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which the sensor cannot detect the signals:
- When the reflector of the vehicle ahead is positioned high on the vehicle (trailer, etc.).
- When the reflector on the vehicle ahead is missing, damaged or covered.
- When the reflector of the vehicle ahead is covered with dirt, snow and road spray.
- When the snow or road spray from traveling vehicles reduces the sensor's visibility.
- When dense exhaust or other smoke (black smoke) fr om vehicles reduces the sensor's visibility.
- When excessively heavy baggage is loaded in the rear seat or the luggage room of own vehicle.
- When the vehicle is towing a trailer, etc.
The ICC system is designed to automatic ally check the sensor's operation within the limitation of the system.
When the sensor is covered with dirt or is obstruct ed, the system will automatically be canceled. If the sen-
sor is covered with ice, a transparent or translucent vinyl bag, etc., the ICC system may not detect them. In
these instances, the vehicle-to-vehicle distance control mode may not cancel and may not be able to main-
tain the selected following distance from the vehicle ahead. Be sure to check and clean the sensor regularly.
