LASER BEAM AIMING ADJUSTMENT
Revision: 2004 November 2004 FX35/FX45
5. Pivot the edge of the target board 20° to either side.
NOTE:
Approx. 50 mm (1.97 in) shift rates the 20° movement.
6. Do not place anything in the space shown in the figure (view from top).
NOTE:
In case the space shown in the illustration is not available, make space by covering the side of the target
board with a 400 mm (15.75 in)-size frosted black board or black cloth.
Aiming AdjustmentAKS006YM
CAUTION:

Complete all necessary work for laser beam adjustment until the adjustment completes as shown
in the procedure. If the procedure does not complete, the ICC system is inoperable.

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER on the
data link connector.

CONSULT-II FunctionAKS006YU
DESCRIPTION
CONSULT-II executes following functions by combining data reception and command transmission via com-
munication line from ICC unit.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to
data link connector, which is located under LH dash panel near
the hood opener handle.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “ICC” on the selection screen.
If “ICC” is not indicated, go to GI-40, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
Test mode Function
WORK SUPPORT

Touch any of “MODE 1”, “MODE 2”, “MODE 3” to check that fol-
lowing operation condition is caused by operating monitor and
brake pedal.

“START” is displayed 10 seconds after operation start. (Active
test is completed.)
Self-Diagnostic FunctionAKS006YV
WITH CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-9, "ACTION
TEST" .
2. Stop vehicle, turn ignition switch OFF, then connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.

TROUBLE DIAGNOSIS — GENERAL DESCRIPTION
Revision: 2004 November 2004 FX35/FX45
CAUTION:
If “ICC” cannot be shown after several attempts, the ICC unit may have had malfunction. Repair or
replace it. Refer to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Self-diagnostic result appears on screen. If “NO DTC ···” is shown, check ICC warning lamp. If any mal-
function 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.
7. Start engine and touch “START”, “ICC”, “SELF-DIAG RESULT”, and “ERASE” on CONSULT-II display in
turn to erase the memory.
CAUTION:
If the memory does not erase, go to 5.
8. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC warning
lamp does not illuminate.
WITHOUT CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-9, "ACTION
TEST" .
2. Stop the vehicle to start the self-diagnosis.
3. Turn ignition switch OFF.
4. Turn ignition switch ON, and within 5 to 10 seconds, press
ACCEL/RES switch 5 times. Then press COAST/SET switch 5
times to start self-diagnosis.
CAUTION:

Do not start the engine.

Do not turn the ON/OFF switch ON.

When operation above is not completed within 5 to 10 sec-
onds, start again from above go to 3.

If self-diagnosis mode cannot be started after several
attempts, the ICC unit may have had malfunction. Repair or
replace it. Refer to ACS-37, "
SELF-DIAGNOSIS BY ICC SYS-
TEM DISPLAY 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.
