CHIME DOES NOT SOUND

Diagnosis Procedure

INFOID:0000000005146013

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.

• 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. Refer to 

CCS-65, "Diagnosis Procedure"

.

YES

>> Determine preceding vehicle detection status when malfunction occurred. If chime should have

sounded replace ICC unit. Refer to 

CCS-71, "ICC Unit"

Perform ICC system running test. Refer

to 

CCS-8, "ACTION TEST : ICC System Running Test"

.

NO

>> GO TO 2

2.

CAN COMMUNICATION INSPECTION

1. With -self-diagnosis, check “CAN COMM CIRCUIT”.
Does "CAN COMM CIRCUIT" display with self-diagnosis?

YES

>> Refer to 

CCS-24, "DTC 20 CAN COMM CIRCUIT"

.

NO

>> Replace combination meter. Refer to 

MWI-100, "Removal and Installation"
