1. Go to operation check after asking the cust omer for symptom information. Refer to ACS-11, "ICC System
Running Test".
2. Stop vehicle, turn ignition swit ch OFF, then connect CONSULT-III.
3. With engine started, check “Self Diagnostic Result” of ICC system.
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-35, "
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 select “Self Diagnosti c Result” of ICC system, and erase DTC.
NOTE:
If the memory does not erase, go to 5.
8. Perform ICC system running test (drive vehicle wi th ICC system ON), and make sure that ICC warning
lamp does not illuminate.
WITHOUT CONSULT-III
1. Go to operation check after asking the cust omer for symptom information. Refer to ACS-11, "ICC System
Running Test".
2. Stop the vehicle to start the self-diagnosis.
3. Turn ignition switch OFF.
4. From 5 seconds through 15 seconds after turning ignition switch ON, press RESUME/ACCELERATE switch 5 times, and SET/
COAST switch 5 times.
NOTE:
 Never start engine.
 Never turn the MAIN switch ON.
 When operation above is not completed from 5 secondsthrough 15 seconds, 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-59, "
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.
NOTE:
 DTC will disappear after 5 minutes.
 When more than one malfunction is detected, a maxi mum of 3 code numbers can be stored; the latest
malfunction will be displayed first.
6. Check ACS-35, "
