Procedure
INFOID:0000000005145973
CAUTION:
• The laser beam aiming adjustment can not be performed without CONSULT-III.
• 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-III.
4. Check system operation after the adjustment.

• Place the vehicle on level ground. Shift the transmi ssion 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 sus-
pension system. Refer to SCS-7, "

INSPECTION AND ADJUSTMENT
NOTE:
If the adjustment screen does not appear on CONSULT-III 10 sec. after touching “LASER BEAM ADJUST”
screen, the following 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 adjustablerange.
• The area is not suitable for the adjustment work.
• ICC sensor is not clean.
>> GO TO 2
2.LASER BEAM AIMING CONFIRMATION
After the CONSULT-III displays “ADJ UST THE VERTICAL OF LASER BEAM AIMING” turn the vertical adjust-
ing screw until “U/D CORRECT” value is set in the range of ±4.
NOTE:
• Turn the screw slowly. The value on the CONSULT-III is slower
than the actual movement of the ICC sensor. Wait 2 seconds
between each adjustment. Also, during adjustment 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.
• Turning the screw clockwise raises the ICC sensor and counter- clockwise lowers the ICC sensor.
>> GO TO 3
3.LASER BEAM AIMING CONFIRMATION
1. 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.
2. When “COMPLETED THE VERTICAL AIMING OF LASER BEAM” appears on screen, touch “END”.
NOTE:
Be sure that the margin of “U/D CORRECT” is within ±4 when the ICC sensor unit is untouched.
3. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER BEAM AIMING” is on screen and wait
while the horizontal adjustment is made automatically. (maximum: 10 seconds).
4. Confirm that “NORMALLY COMPLETED” is displayed on CONSULT-III and close the aiming adjustment procedure by touching “END”.
NOTE:
Complete all the procedures once “LASER BEAM AD JUST” mode is entered in CONSULT-III. When the
procedure is discontinued, the ICC system is inoperable.
>> LASER BEAM AIMING ADJUSTMENT END.
CHECK AFTER THE ADJUSTMENT
Test the ICC system by performing the ICC System Running Test. Refer to CCS-8, "ACTION TEST : ICC Sys-
tem Running Test" .

• 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-vehicl e 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 automatica lly 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 DRIV-
ING 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 DI STANCE 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 vehi cle 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 w hen ACCEL/RES switch is operated when driving 40 km/h
(25 MPH) or above, after canceling vehicle-to-v ehicle distance control mode by operating the CANCEL
switch.
CHECK ON/OFF SWITCH OPERATION
1. Start the engine. Then, check that the following operations are performed 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.
CHECK FOR ACCEL/RES, COAST/SET, CANCEL SWITCHES
1. Check if ACCEL/RES, COAST/SET, CANCEL sw itches operate smoothly.
2. Check if switch buttons r ebound as the buttons are released.
CHECK FOR DISTANCE SWITCH
1. Start the engine.
2. Press the ON/OFF switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(long) →(middle)→ (short).
