DETAILED FLOW

1.

COLLECT THE INFORMATION FROM THE CUSTOMER

It is also important to clarify customer complaints before inspection. First of all, reproduce symptoms and
understand them fully. Ask customer about his/her complaints carefully. In some cases, it is necessary to
check symptoms by driving vehicle with customer.

CAUTION:

Customers are not professional. It is dangerous to make an easy guess like “maybe the customer
means that...,” or “maybe the customer mentions this symptom”.

.

3.

Check the power steering gear for damages, cracks and fluid leakage. Refer to 

ST-36, "Inspection"

.

4.

Check the relief oil pressure. Refer to 

ST-42, "Inspection"

.

>> GO TO 3.

3.

DIAGNOSIS CHART BY SYMPTOM

Perform the diagnosis by symptom. Refer to 

STC-18, "Diagnosis Procedure"
