< SYMPTOM DIAGNOSIS >
ICC SYSTEM FREQUENTLY CANNOT DETECT THE VEHICLE AHEAD/ DETEC-TION ZONE IS SHORT
ICC SYSTEM FREQUENTLY CANNOT DETECT THE VEHICLE AHEAD/
DETECTION ZONE IS SHORT
Diagnosis ProcedureINFOID:0000000003776967
The detection function may become disrupted 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 v ehicle 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.
Is the ICC sensor window clean and free of obstruction?
YES >> GO TO 2
NO >> If any contamination or foreign materials ar e found, remove them. Then perform ICC system run-
ning test. Refer to CCS-8, "
ACTION TEST : ICC System Running Test".
2.CHECK FUNCTION
1. After performing laser beam aiming adjustment, perform ICC system running test. Refer to CCS-8,
"ACTION TEST : ICC System Running Test". Check that preceding vehicle detection performance has
been improved.
Is the ICC system operating normally?
YES >> INSPECTION END.
NO >> • Replace ICC sensor and perform laser beam aiming adjustment. Refer to CCS-71, "
ICC Sen-
sor".
• Perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC System Running Test".

Diagnosis ProcedureINFOID:0000000003776968
1.VISUAL CHECK
With ignition switch turned ON (engine not started), che ck that all indicator lamps in ICC system display are
continuously lit. (Check for a missing segment in preceding vehicle detection display.)
Does the display operate normally?
YES >> GO TO 2
NO >> Check combination meter. Refer to MWI-24, "
Diagnosis Description".
2. VISUAL CHECK
Check ICC sensor window for contamination and foreign materials.
Is the ICC sensor window clean and free of obstruction?
YES >> If any contamination or foreign materials are found, remove them. Perform ICC system running
test. Refer to CCS-8, "
ACTION TEST : ICC System Running Test".
NO >> GO TO 3
3.VISUAL CHECK
Check ICC sensor window for cracks and scratches.
Is the ICC sensor window intact?
YES >> GO TO 4
NO >> • Replace ICC sensor and perform laser beam aiming adjustment. Refer to CCS-71, "
ICC Sen-
sor".
• Perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC System Running Test".
4.ADJUST ICC SENSOR
• After performing laser beam aiming adjustment, perform ICC system running test. Refer to CCS-8, "
ACTION
TEST : ICC System Running Test". Check that preceding vehicle detection performance has been improved.
Is the ICC system operating normally?
YES >> INSPECTION END.
NO >> • Replace ICC sensor and perform laser beam aiming adjustment. Refer to CCS-71, "
ICC Sen-
sor".
• Perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC System Running Test".
