CHIME DOES NOT SOUND

CHIME DOES NOT SOUND

Description

INFOID:0000000001606961

The chime may not sound occasionally in the following cases even if the distance from the vehicle ahead is
short:
• When the speed difference from that of the vehicle ahead is small (both vehicles driving at similar speed).
• When the vehicle ahead drives at faster speed (the actual distance is increasing).
• When depressing the accelerator pedal.
• Chime does not sound when the vehicle is not driving.
• Chime does not sound when the system does not detect any vehicle ahead. (Diagnose the conditions under

which the system is detecting the vehicle ahead and when the system is malfunctioning. If there is any mal-
function in detecting the vehicle ahead, check the system following the 

CCS-105, "Diagnosis Procedure"

).

Diagnosis Procedure

INFOID:0000000001606962

1.

CHECK ICC WARNING CHIME

With CONSULT-III

1.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK THE MALFUNCTION SYMPTOM DURING BUZZER OPERATION

Determine preceding vehicle detection status when malfunction occurred. If chime should have sounded: after
replacing ICC sensor integrated unit and adjust laser beam aiming.

>> INSPECTION END

3.

PERFORM SELF-DIAGNOSIS OF ICC SENSOR INTEGRATED UNIT

1.

Perform self-diagnosis of ICC sensor integrated unit.

2.

Check if DTC “CAN COMM CIRCUIT [U1000]” (DTC 100) is detected.

Is any DTC detected?

MWI-100, "DTC Index"

.

Is any DTC detected?

YES

>> GO TO 7.

NO
