Description
 In general, customers have their own criteria for a pr oblem. Therefore, it is important to understand the
symptom and status well enough by asking the customer about his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the inte rview sheet referring to the interview points.
 In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.

6.IDENTIFY MALFUNCTIONING SYSTEM WI TH “DIAGNOSIS CHART BY SYMPTOM”
Use TM-165, "
Symptom Table" from the symptom inspection result in step 4. Then identify where to start per-
forming the diagnosis based on possible causes and symptoms.
>> GO TO 8.
7.REPAIR OR REPLACE THE MALFUNCTIONING PARTS
Repair or replace the detected malfunctioning parts.
Reconnect parts or connector after repairing or replacing, and then erase DTC if necessary.
>> GO TO 8.
8.FINAL CHECK
Perform “DTC CONFIRMATION PROCEDURE” again to make sure that the repair is correctly performed.
Check that malfunctions are not reproduced when obtai ning the malfunction information from the customer,
referring to the symptom inspection result in step 3 or 4.
Is DTC or malfunction symptom reproduced?
YES-1 >> DTC is reproduced: GO TO 5.
YES-2 >> Malfunction symptom is reproduced: GO TO 6.
NO >> Before delivering the vehicle to the customer, make sure that DTC is erased.
