test is completed.)
Self-Diagnostic FunctionEKS00BLY
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.

3. With engine started, touch “START”, “ICC”, “SELF-DIAG RESULTS” on CONSULT-II screen in this order.
CAUTION:
If “ICC” cannot be shown after several attempts, the ICC unit may be malfunctioning and should
be replaced. Refer to ACS-60, "
ICC Unit" .
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. Refer to ACS-36, "
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.
CAUTION:
DTC of an existing malfunction will not erase. If the memory does not erase, GO TO step 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 wait 5 seconds. Press ACCEL/RES
switch 5 times, and then press COAST/SET switch 5 times all
within 5 seconds to start self-diagnosis.
CAUTION:

Do not start the engine.

Do not press the ICC ON/OFF switch ON.

When operation above is not completed within the 5 to 10
second window, DTC will not be displayed.

If self-diagnosis mode cannot be started after several
attempts, the ICC unit may be malfunctioning and should be
replaced. Refer to ACS-33, "
SELF-DIAGNOSIS BY ICC SYS-
TEM DISPLAY WILL NOT RUN" .
5. When self-diagnosis mode is started, DTCs are shown on set vehicle speed indicator.
CAUTION:

DTC will disappear after 5 minutes.

2. CAN COMMUNICATION INSPECTION
With CONSULT-II
1. With CONSULT-II self-diagnosis, check “CAN COMM CIRCUIT”.
OK or NG
OK >> Refer to ACS-38, "DTC 20 CAN COMM CIRCUIT" .
NG >> Replace combination meter. Refer to IP-13, "
Combination Meter" . Erase DTC and perform ICC
system running test. Refer to ACS-9, "
ICC System Running Test" . Then perform self-diagnosis of
ICC system again.
Symptom 6: Driving Force Is HuntingEKS00BMP
1. CHECK ECM
1. Perform self-diagnosis of ECM.
OK or NG
OK >> Refer to ACS-57, "Symptom 7: The ICC System Frequently Cannot Detect the Vehicle Ahead/The
Detection Zone is Short" .
NG >> Repair as necessary. Erase DTC and perform ICC system running test. Refer to ACS-9, "
ICC
System Running Test" . Then perform self-diagnosis of ICC system again.
Symptom 7: The ICC System Frequently Cannot Detect the Vehicle Ahead/The
Detection Zone is Short
EKS00BMQ
The detection function may become unstable in the following cases:

When the reflector of the vehicle ahead is small or not clean enough to reflect the laser.

When driving a road with extremely sharp corners.

When the laser cannot detect the reflector of the vehicle ahead as the vehicle ahead is passing a hill or
passing the peak.
1. VISUAL CHECK
1. Check ICC sensor body window for contamination and foreign materials.
OK or NG
OK >> If any contamination or foreign materials are found, remove them. Then perform ICC system run-
ning test. Refer to ACS-9, "
ICC System Running Test" .
NG >> GO TO 2.
2. CHECK FUNCTION
1. After performing laser beam aiming adjustment, perform ICC system running test. Refer to ACS-9, "
ICC
System Running Test" . Check that preceding vehicle detection performance has been improved.
OK or NG
OK >> Inspection End.
NG >>

Replace ICC sensor and perform laser beam aiming adjustment. Refer to ACS-60, "ICC Sen-
sor" .

Perform ICC system running test. Refer to ACS-9, "ICC System Running Test" . Then perform
self-diagnosis of ICC system again.
Symptom 8: The System Does Not Detect the Vehicle Ahead at AllEKS00BMR
1. VISUAL CHECK
1. With ignition switch turned ON (engine not started), check that all indicator lamps in ICC system display
are continuously lit. (Check for a missing segment in preceding vehicle detection display.)
OK or NG
OK >> GO TO 2.
NG >> Check combination meter. Refer to DI-17, "
How to Proceed With Trouble Diagnosis" .
