Trouble Diagnosis

AKS00D61

HOW TO PERFORM TROUBLE DIAGNOSIS

1.

Confirm the symptom or customer complaint.

2.

Understand operation description and function description. Refer to 

DI-60, "System Description"

 .

3.

Perform the preliminary check. Refer to 

DI-69, "PRELIMINARY CHECK"

 .

4.

Select “METER A/C AMP” on CONSULT-II, and perform self-diagnosis of unified meter and A/C amp.
Refer to 

DI-31, "CONSULT-II Function (METER A/C AMP)"

 . When no malfunction detected, go to next

step 5. When malfunction detected, go to 

DI-16, "Symptom Chart 2"

  in “COMBINATION METER”

5.

Check symptom and repair or replace the cause of malfunction.

6.

Does the warning chime operate normally? If so, GO TO 7. If not, GO TO 5.
