HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a problem. It is important to fully understand the symptoms or
conditions for a customer complaint.
Make good use of the two sheets provided, “INFORMATION FROM CUSTOMER” (AT- 2 8 0 , "
Information from
Customer") and “DIAGNOSTIC WORKSHEET” (AT-281, "Diagnostic Worksheet"), to perform the best trou-
bleshooting possible.
5.oFor self-diagnosis NG items, inspect each component. Repair or replace the damaged parts.AT-273,

6.oPerform all ROAD TEST and re-mark required procedures.AT-291,
"Road Test"
7.oPerform the Diagnostic Procedures for all remaining items marked NG. Repair or replace the damaged parts.
Refer to the Symptom Chart when you perform the procedures. (The chart also shows some other possible
symptoms and the component inspection orders.)AT-308,
