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

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, "
