TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2007 April2007 M35/M45
3. CHECK D RANGE SWITCH
With CONSULT-II
With “A/T” “DATA MONITOR”, check if “SLCT LVR POSI” operates normally.
OK or NG
OK >> 1. Replace ICC sensor integrated unit, and adjust laser beam aiming.
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
NG >> 1. Perform “A/T” self-diagnosis. Refer to AT- 9 0 , "
CONSULT-II Function (A/T)" .
2. After repairing or replacing applicable item, erase DTC and perform ICC system running test.
Then perform self-diagnosis of ICC system again.
Symptom 5: Chime Does Not SoundNKS004DO
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 malfunction in detecting the vehicle ahead, check the system following the ACS-67, "
Symptom 7: ICC
System Frequently Cannot Detect the Vehicle Ahead/ Detection Zone Is Short" ).
1. CHECK ICC WARNING CHIME
With CONSULT-II
With “ICC” “ACTIVE TEST”, check if “ICC BUZZER” operates normally.
OK or NG
OK >> 1. Determine preceding vehicle detection status when malfunction occurred. If chime should have
sounded: after replacing ICC sensor integrated unit and adjust laser beam aiming.
2. Erase DTC and perform ICC system running test, and then perform self-diagnosis of ICC sys-
tem again.
NG >> GO TO 2.
2. PERFORM ICC SENSOR INTEGRATED UNIT SELF-DIAGNOSIS
With CONSULT-II
1. Perform self-diagnosis.
2. Check if “DTC 100 CAN COMM CIRCUIT” is indicated.
Is it indicated?
YES >> CAN communication inspection. Refer to ACS-61, "DTC 100 CAN COMM CIRCUIT" .
NO >> GO TO 3.
3. CHECK UNIFIED METER AND A/C AMP.
With CONSULT-II
Perform “METRE A/C AMP” self-diagnosis. Refer to DI-31, "
CONSULT-II Function (METER A/C AMP)" .
Is malfunction indicated?
YES >> 1. Repair or replace applicable item.
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
NO >> GO TO 4.
