Recheck the symptom and check that the symptom is not reproduced on the same conditions.
Is the symptom reproduced?
YES>>GO TO 3.
NO>>INSPECTION END
Description
In general, customers have their own criteria for a problem. 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 interview sheet referring to the interview points.
In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.
