5.CHECK THE ICC TARGET BOARD INSTALLATION AREA
Do not place anything other than ICC target board in the space shown in the figure (view from top).
NOTE:
In case the space shown in the figure is not avail able, cover the side of the ICC target board with a 1400
mm(4.6 ft)-size frosted black board or black cloth.
>> Go to CCS-75, "
Work Procedure (Laser Beam Aiming Adjustment)".
Work Procedure (Laser B eam Aiming Adjustment)INFOID:0000000006224296
DESCRIPTION
 Adjust the laser beam aiming in a vertical di rection with CONSULT-III as per the following.
 The laser beam aiming adjustment in a horizontal dire ction is performed automatically with CONSULT-III.
CAUTION:
 Never look directly into the laser beam source (ICC sensor body window) during laser beam aiming
adjustment.
 Perform all necessary work for laser beam aiming adjustment until the adjustment completes as
shown in the procedure. If the procedure do es not complete, the ICC system is inoperable.
1.SET CONSULT-III TO THE LASER BEAM AIMING ADJUSTMENT MODE
1. Start the engine.
2. Connect CONSULT-III and select “Work support” of “LASER”.
3. Select “LASER BEAM ADJUST” after t he “Work support” screen is displayed.
4. Select “START” after the “LASER BEAM ADJUST” screen is displayed.
NOTE:
If the adjustment screen does not appear within approx imately 10 seconds after “LASER BEAM ADJUST”
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.
>> GO TO 2.
2.LASER BEAM AIMING ADJUSTMENT
After “ADJUST THE VERTICAL OF LASER BEAM AIMI NG” is displayed on CONSULT-III screen, adjust by
turning the up-down direction adjusting screw until “U/D CORRECT” becomes ±4 or less.

ICC SENSOR : Diagnosis ProcedureINFOID:0000000006224334
1.VISUAL CHECK 1
Check ICC sensor body window for c ontamination and foreign materials.
Does contamination or foreign materials adhere?
YES >> Wipe out the contamination and foreign materials from the ICC sensor body window.
NO >> GO TO 2.
2.VISUAL CHECK 2
Check ICC sensor body window for cracks and scratches.
Is it found?
YES >> Replace the ICC sensor. Refer to CCS-176, "Exploded View".
NO >> GO TO 3.
3.INTERVIEW
1. Ask if there is any trace of contamination or fo reign materials adhering to the ICC sensor body window.
2. Ask if ICC sensor body window was frosted during driving or if vehicle was driven in snow.
3. Ask if ICC sensor body window wa s temporarily fogged. (Windshield glass may also tend to fog, etc.)
Is any of above conditions seen?
YES >> Explain to the customer about the differ ence between the contamination detection function and
the indication when the malfunction is detected and tell them “This is not malfunction”.
NO >> Replace the ICC sensor. Refer to CCS-176, "
Exploded View".

Operation Condition
ADAS control unit performs the control when the following conditions are satisfied.
 When the DCA system setting on the navigation screen is ON.
 When the dynamic driver assistance switch is turned to ON.
 When the brake pedal is not depressed.
 When the vehicle speed is above approximately 5 km/h (3 MPH).
 When the vehicle ahead is detected.
 When the ICC system is not set.
No Operation Condition
The ADAS control unit is not operat e when the system is under any condi tions of the no operation condition.
 When the brake pedal depressed.
 When the ICC system is set.
 When the system judges that the vehicle co mes to a standstill by the system control.
 When the vehicle ahead is not detected.
Operation Cancellation Condition
The ADAS control unit cancels the operation when the syst em is under any conditions of the operation cancel-
lation condition.
 When the dynamic driver assistance switch is turned to OFF.
 When the system malfunction occurs.
 When ABS or VDC (including the TCS) operates.
 When the VDC is turned OFF.
 When the SNOW mode switch is turned ON.
 When the 4WD shift switch is turned to not AUTO position.
 When driving into a strong light (i.e., sunlight).
 When the ICC sensor body window is dirty and the measurement of the distance between the vehicles
becomes difficult.
Operation At The Driver Operation
Give priority to the driver operation in the following situation.
When vehicle approaches a vehicle ahead If the driver is not depressing the acceler-
ator pedal, the system activates the
brakes to decelerate smoothly as neces-
sary
If the driver is depressing the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to re-
lease the accelerator pedal
When brake operation by driver is required The system alerts the driver by a warning
chime and blinking the vehicle ahead de-
tection indicator. If the driver is depressing
the accelerator pedal after the warning,
the system moves the accelerator pedal
upward to assist the driver to switch to the
brake pedal
Deceleration control It transmits the brake fluid
pressure control signal to the ABS actuator and electric unit (control unit) via
CAN communication and performs the brake control
Accelerator pedal actuation
control It transmits the accelerator pedal feedback force control signal to the accelerator pedal actuator via ITS
communication and controls the accelerator pedal in the upward directionJSOIA0222ZZ
