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.

METER LAMP

Start engine.

Touch “ON” and “OFF” to check if MAIN switch indicator lamp
and ICC system warning lamp illuminate as in the following
chart.
STOP LAMP
Touch “ON” and “OFF” to check if stop lamp operates as in the fol-
lowing chart.
Self-Diagnostic FunctionNKS004CY
WITH CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-12, "ACTION
TEST" .
2. Stop vehicle, turn ignition switch OFF, then connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.
3. With engine started, touch “START (NISSAN BASED VHCL)”, “ICC”, “SELF-DIAG RESULTS” on CON-
SULT-II screen in this order.
CAUTION:
If “ICC” cannot be shown after several attempts, the ICC sensor integrated unit may have had mal-
function. Repair or replace it. Refer to GI-39, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. “DTC RESULTS” and “TIME” are indicated on “SELF-DIAG RESULTS”. “TIME” is used as a reference
data of diagnosis. It shows when malfunction is detected.
NOTE:
“TIME” shows the following.

0: malfunction is detected at present (from malfunction detection to ignition switch OFF).
CAN communication ([U1000], [U1010])

1 ~ 39: Displays when it is normal at present and finds malfunction in the past. It increases like
0→1→2...38→39 after returning to the normal condition whenever IGN OFF→ON. If it is over 39, it is
fixed to 39 until the self-diagnostic results are erased. It returns to 0 when malfunction is detected again
in the process.
Other than CAN communication (other than [U1000], [U1010])

1 ~ 49: Displays when it is normal at present and finds malfunction in the past. It increases like
0→1→2...48→49 after returning to the normal condition whenever IGN OFF→ON. If it is over 49, it is
fixed to 49 until the self-diagnostic results are erased. It returns to 0 when malfunction is detected again
in the process.
If “NO DTC...” is shown, check ICC system warning lamp. If any malfunction is indicated, GO TO step 5.
5. According to ACS-40, "
Diagnostic Trouble Code (DTC) Chart" , perform appropriate check, and repair or
replace malfunctioning part as necessary.
6. Turn ignition switch OFF.

switch 5 times.
CAUTION:

Never turn the MAIN switch ON.

When operation above is not completed from 5 seconds
through 15 seconds, start again from above go to 3.

If self-diagnosis mode cannot be started after several
attempts, the ICC sensor integrated unit may have had
malfunction. Repair or replace it. Refer to ACS-36, "
SELF-
DIAGNOSIS BY DOT MATRIX LCD WILL NOT RUN" .
5. When self-diagnosis mode is started, DTC are shown on set vehicle speed indicator.
CAUTION:

DTC will disappear after 5 minutes.

When more than one malfunction is detected, a maximum of 3 code numbers can be stored; the
latest malfunction will be displayed first.
6. Check ACS-40, "
Diagnostic Trouble Code (DTC) Chart" , and repair or replace if necessary.
7. After repair, erase DTC stored in the ICC sensor integrated unit.
8. DTC 55 will be shown.
9. Turn ignition switch OFF to exit the diagnosis.
10. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC system
warning lamp (Orange) does not illuminate.
