VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
SET CHECKING
1. Press the ON/OFF switch for less than 1.5 seconds.
2. Drive the vehicle between 40 km/h (25 MPH) and 144 km/h (89 MPH).
3. Push the COAST/SET switch.
4. Confirm that the desired speed is set as the COAST/SET switch is released.
NOTE:

When there is no vehicle ahead, drive at the set speed steadily.

When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.

The set vehicle speed is displayed on the ICC system indicator in the combination meter.
CHECK FOR INCREASE OF THE CRUISING SPEED
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed increases by 1.6 km/h (1 MPH) as ACCEL/RES switch is pushed.
NOTE:
The maximum set speed of the vehicle-to-vehicle distance control mode is 144 km/h (89 MPH).
CHECK FOR DECREASE OF THE CRUISING SPEED
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1.6 km/h (1 MPH) as COAST/SET switch is pushed.
NOTE:

Vehicle-to-vehicle distance control mode is automatically turned off when the driving speed lowers to 32
km/h (20 MPH) due to the deceleration of the vehicle ahead.

The minimum set speed of the vehicle-to-vehicle distance control mode is 40 km/h (25 MPH).
CHECK FOR THE CANCELLATION OF VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
(NORMAL DRIVING CONDITION) IN THE FOLLOWING CASES:
1. When the brake pedal is depressed after the system is turned on.
2. When the selector lever is shifted to the "N" (Neutral) position.
3. When the system is turned off.
4. When CANCEL switch is operated.
CHECK FOR RESTORING THE SPEED THAT IS SET BY VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE BEFORE CANCELLATION
1. Cancel the system by depressing the brake. Then, check that the speed before cancellation is restored
when pressing ACCEL/RES switch with vehicle speed at 40 km/h (25 MPH) or above.
2. Cancel the system by shifting the selector lever to “N”. Then, check if the speed set before the cancella-
tion is restored when ACCEL/RES switch is pressed.
3. Check if the speed previously set is restored when ACCEL/RES switch is operated when driving 40 km/h (25 MPH) or above, after canceling vehicle-to-vehicle distance control mode by operating the CANCEL
switch.
CHECK ON/OFF SWITCH OPERATION
1. Start the engine. Then, check that the following operations areperformed correctly.
2. Vehicle-to-vehicle distance control mode is displayed when ON/ OFF switch is pressed ON. Vehicle-to-vehicle distance control
mode goes off when ON/OFF switch is turned to OFF.
3. Turn off the ignition switch while ON/OFF switch is ON. Turn the ignition switch back to ON and confirm that CRUISE lamp and
ICC system display are OFF.

LASER BEAM AIMING ADJUSTMENT
Revision: November 20092006 QX56
LASER BEAM AIMING ADJUSTMENTPFP:00026
Outline of Laser Beam Aiming Adjustment ProcedureEKS00BLN
CAUTION:

The laser beam aiming adjustment cannot be performed without CONSULT-II.

The laser beam aiming adjustment must be performed every time the ICC sensor is removed,
installed or has been moved as a result of a collision.
1. Prepare the vehicle and the work area.
2. Set up the ICC target board. For details, refer to Technical Service Bulletin.
3. Adjust the sensor following the procedure on CONSULT-II.
4. Check system operation after the adjustment.
PreparationEKS00BLO

Place the vehicle on level ground. Shift the transmission into "P" position and release the parking brake.

Adjust the tire pressure to the specified value.

See that there is no load in the vehicle. Coolant, engine oil and fuel should be filled to correct level.

Check that the vehicle suspension has been adjusted to the standard height by the load leveling rear air
suspension system. Refer to RSU-12, "
Basic Inspection" .

Clean the sensor with a soft cloth.
Setting up the ICC Target BoardEKS00BLP
CAUTION:
Accuracy in setting up the ICC target board is essential for the laser beam aiming adjustment.
For details, refer to Technical Service Bulletin.
ADJUSTING HEIGHT OF THE TARGET
1. Attach a triangle scale as shown.Tool number : KV99110100 (J-45718)

2. Adjust the height of the target stand so that the point of the trian-
gle aims above the center of the ICC sensor.
ADJUSTING THE POSITION OF THE TARGET BOARD STRING
1. Attach a scale or straightedge (at least 350 mm [14 in] or
longer).
2. Suspend a string with a weight on the end 218 mm (8.6 in) to the left side of the target board center.
POSITIONING THE TARGET
1. Suspend a string with weights on each end over the centerline of the vehicle. The string should lay overthe center of the front and back bumpers. Mark these centerpoints on the ground at each weight.
2. Connect the two center points using a string. Extend the string an additional 5 m (16 ft) beyond the front centerpoint and mark
the floor. Position the target board weight on this mark.
3. Relocate the suspended string from the left side of the target board to the center of the target board. Mark this point on the ground.

4. Pivot the target board on its center mark 20° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift will produce a 20 ° movement.
5. Remove any items in the shaded space shown in the figure.
NOTE:
In case the background space shown in the illustration is not available, or if the background is light col-
ored, place a 400 mm (15.75 in) long frosted black board or black cloth to both sides of the target board.
Sensor AdjustmentEKS00BLQ
CAUTION:

Complete all necessary steps for laser beam adjustment until the CONSULT-II indicates "COM-
PLETED". If the procedure does not complete, the ICC system is inoperable.

If CONSULT-II is used without connection to the CONSULT-II CONVERTER, malfunctions might be
detected during self-diagnosis.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

6. Touch “LASER BEAM ADJUST ”.
7. Touch “START”.
CAUTION:
If the adjustment screen does not appear on CONSULT-II 10
sec. after touching “LASER BEAM ADJUST” screen, the fol-
lowing causes may be considered:

Target is not set accurately.

There is not enough space beside the target.

Deformation of vehicle or inappropriate installation of
sensor. Sensor may be installed out of the adjustable
range.

The area is not suitable for the adjustment work.

ICC sensor is not clean.
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the vertical adjusting screw until
“U/D CORRECT ” value is set in the range of ±4.
CAUTION:
Turn the screw slowly. The value on the CONSULT-II is
slower than the actual movement of the ICC sensor. Wait 2
seconds between each adjustment. Also, during adjust-
ment work, do not block the ICC sensor lens with your hand
or body. In that case, there are times when aiming cannot
be conducted correctly.
NOTE:
Turning the screw clockwise raises the ICC sensor and counter-
clockwise lowers the ICC sensor.
9. When “U/D CORRECT ” value indicates ± 4, confirm that the value remains within ±4 for at least 2 seconds
while nothing is touching the ICC sensor.
When “COMPLETED THE VERTICAL AIMING OF LASER
BEAM ” appears on screen, touch “END ”.
CAUTION:
Be sure that the margin of “U/D CORRECT” is within ±4
when the ICC sensor unit is untouched.
10. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER
BEAM AIMING ” is on screen and wait while the horizontal
adjustment is made automatically. (maximum: 10 seconds).

“END ”.
CAUTION:
Complete all the procedures once “LASER BEAM ADJUST”
mode is entered in CONSULT-II. When the procedure is dis-
continued, the ICC system is inoperable.
CHECK AFTER THE ADJUSTMENT
Test the ICC system by performing the ICC System Running Test. Refer to ACS-9, "ICC System Running Test"
.
