Diagnosis Procedure

INFOID:0000000000965478

CHECK MAIN SWITCH

With COUSULT-III

Start engine.

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

Is the inspection result normal?

YES

>> GO TO 2.

>> GO TO 5.

CHECK UNIFIED METER AND A/C AMP.

With CONSULT-III

With “DATA MONITOR” of “METER”, check if “CRUISE IND” operate normally.

Is the inspection result normal?

YES

>> GO TO 3.

>> GO TO 5.

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

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

Check if DTC is detected. Refer to

MWI-97, "DTC Index"

Is any DTC detected?

YES

>> Repair or replace applicable item.

>> GO TO 4

PERFROM SELF-DIAGNOSIS MODE OF COMBINATION METER

Perform self-diagnosis mode of combination meter. Refer to

MWI-35, "Diagnosis Description"

Check that the multi information display operates normally.

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

>> INSPECTION END

PERFORM SELF-DIAGNOSIS OF ICC SENSOR INTEGRATED UNIT

Perform self-diagnosis of ICC sensor integrated unit.

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

Is it DTC detected?

YES

>> GO TO 6.

>> GO TO 7.

CAN COMMUNICATION INSPECTION
