Diagnostic Work Sheet

INFOID:0000000010833856

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.
