How to Proceed With Trouble Diagnosis

AKS004H7

Confirm the symptom or customer complaint.

Understand operation description and function description. Refer to

DI-76, "System Description"

Perform the preliminary check. Refer to

DI-104, "Preliminary Check"

Start engine.

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

DI-57, "CONSULT-II Function"

After erasing the self-diagnosis result, perform self-diagnosis again. When no malfunction detected, go to
next step 7. When malfunction detected, go to

DI-18, "Symptom Chart 2"

in “COMBINATION METER”.

Check symptom and repair or replace the cause of malfunction.

Does the warning chime operate normally? If so, go to 9. If not, go to 7.
