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 unit may have had malfunction. Repair or
replace it. Refer to GI-39, "
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-42, "
Diagnostic Trouble Code (DTC) Chart" , perform appropriate check, and repair or
replace malfunctioning part as necessary.
6. Turn ignition switch OFF.
7. Start the 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 warning lamp does not illuminate.
WITHOUT CONSULT-II
1. Go to operation check after asking the customer for symptom information. Refer to ACS-11, "ACTION
TEST" .
2. Stop the vehicle to start the self-diagnosis.

7. After repair, erase DTC stored in the ICC 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 warning lamp (Orange) does not illuminate.
Self-Diagnostic Erasing Method
1. Stop the vehicle and turn the ignition switch OFF.
2. Turn ignition switch ON 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.
