1.VISUAL INSPECTION (1)
Check that there is no contamination 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-72, "
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 contaminati on 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 f ogged 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 adjus t laser beam aiming. Refer to CCS-72, "
ICC Sensor".
• Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test".
