1.VISUAL INSPECTION (1)
Check that there is no cont amination and foreign material on ICC sensor body window.
Is the ICC sensor clean?
YES >> GO TO 2
NO >> • Clean ICC sensor. • Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test".
2.VISUAL INSPECTION (2)
Check ICC sensor body window for cracks.
Is the ICC sensor window undamaged?
YES >> GO TO 3
NO >> • Replace ICC sensor and adjust laser beam. Refer to CCS-71, "
ICC Sensor".
• Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test".
3.ASK CUSTOMER FOR DRIVING CONDITIONS
1. Is there any trace of contamination or foreign material on ICC sensor?
2. Is there any possibility that vehicle was driven in snow or ICC sensor was frosted?
3. Is there any possibility that ICC sensor was fogged temporarily? (Front window glass may have also been fogged.)
Was the ICC sensor obstructed by normal conditions?
YES >> Explain system operation and parameters to customer. System may be operating normally.
NO >> • Replace ICC sensor and adjust laser beam aiming. Refer to CCS-71, "
ICC Sensor".
• Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test".

1.CHECK SYMPTOM
Inspect engine cooling system.
Did the engine overheat?
YES >> • Repair cooling system. • Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test". Then perform self-diagnosis of ICC system again.
NO >> • Replace ICC sensor and adjust laser beam aiming. Refer to CCS-71, "
ICC Sensor".
• Erase DTC, then perform ICC system running test. Refer to CCS-8, "
