Diagnosis Procedure

INFOID:0000000001606954

1.

CHECK MAIN SWITCH

With COUSULT-III

1.

Start engine.

2.

With “Data Monitor” of “ICC”, check if “MAIN SW” and “CRUISE LAMP” operate normally.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 5.

2.

CHECK UNIFIED METER AND A/C AMP.

With CONSULT-III

With “Data Monitor” of “METER/M&A”, check if “CRUISE IND” operate normally.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 5.

3.

PERFORM SELF-DIAGNOSIS OF UNIFIED METER AND A/C AMP.

1.

Perform self-diagnosis of unified meter and A/C amp.

2.

Check if DTC is detected. Refer to 

MWI-100, "DTC Index"

.

Is any DTC detected?

YES

>> Repair or replace applicable item.

NO

>> GO TO 4

4.

PERFROM SELF-DIAGNOSIS MODE OF COMBINATION METER

1.

Perform self-diagnosis mode of combination meter. Refer to 

MWI-35, "Diagnosis Description"

.

2.

Check that the multi information display operates normally. 

3.

If it does not operate normally, repair the affected components or replace the combination meter. 

>> INSPECTION END

5.

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 it DTC detected?

YES

>> GO TO 6.

NO

>> GO TO 7.

6.

CAN COMMUNICATION INSPECTION

Perform CAN communication system inspection. Repair or replace the applicable item. Refer to 

CCS-79,

"Diagnosis Procedure"

.

CCS-96
