ACTION TEST
Revision: 2006 January2006 M35/M45
Check For Increase Of Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed increases by 1 MPH (1.6 km/h for CANADA models) as RESUME/ACCELERATE
switch is pushed up.
NOTE:
If the RESUME/ACCELERATE switch is kept pushing up during cruise control driving, the vehicle speed
increases until the switch is released.
The maximum set speed is 90 MPH (144 km/h for CANADA models).
Check For Decrease Of Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed decreases by 1 MPH (1.6 km/h for CANADA models) as SET/COAST switch is
pushed down.
NOTE:
Conventional (fixed speed) cruise control mode is automatically cancelled when the driving speed lowers
to 20 MPH (32 km/h for CANADA models).
The lowest set speed is 25 MPH (40 km/h for CANADA models).
Check For Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal Driving
Condition) In The Following Cases:
Refer to ACS-10, "Check For Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Con-
dition) In The Following Cases:" .
Check For Restoring Speed That Is Set By Conventional (Fixed Speed) Cruise Control Mode
Before ICC Cancellation
Refer to ACS-10, "Check For Restoring Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation" .
Check For MAIN Switch
1. Start engine. Then, check if the following operations are per-
formed correctly.
2. “CRUISE” lamp illuminates and dot matrix LCD goes off when
MAIN switch is pressed “ON” for more than 1.5 seconds, and
then ready for operation. The illumination goes off when MAIN
switch is turned to OFF.
3. “CRUISE” illumination go off when the ignition switch is turned to
OFF while MAIN switch is ON.
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches
1. Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check if switches come up as hand is released from the switches.

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 to the
data link connector.
3. Start engine, wait for at least 10 seconds, and touch “START
(NISSAN BASED VHCL)”.
4. Touch “ICC”.
If “ICC” is not indicated, go to GI-40, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
5. Touch “WORK SUPPORT”.

Self-Diagnostic FunctionNKS004CY
WITH CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-10, "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-40, "
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
12...3839 after returning to the normal condition whenever IGN OFFON. 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
12...4849 after returning to the normal condition whenever IGN OFFON. 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-39, "
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 (NISSAN BASED VHCL)”, “ICC”, “SELF-DIAG RESULTS” 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 system
warning lamp does not illuminate.
WITHOUT CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-10, "ACTION
TEST" .
2. Stop the vehicle and turn ignition switch OFF.
3. Start engine.
4. From 5 seconds through 15 seconds after start engine, press
RESUME/ACCELERATE switch 5 times, and SET/COAST
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, "

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-39, "
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.
Self-Diagnostic Erasing Method
1. Stop the vehicle and turn ignition switch OFF.
2. Start engine and start self-diagnosis.
3. During self-diagnosis mode, press CANCEL switch 5 times, and
DISTANCE switch 5 times in this order.
CAUTION:
Press them within 10 seconds after pressing CANCEL
switch at first.
When operation is not completed within 10 seconds, start
again from step 2 above.
4. DTC 55 will be shown.
CAUTION:
DTC of an existing malfunction will not be erased.
5. Turn ignition switch OFF to exit the diagnosis.
6. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC system
warning lamp (Orange) does not illuminate.
