[5] MATRIX CHART OF PROBLEM SYMPTOMS The suspect circuits or parts for each problem symptom are shown in the table below. Use this table to trouble-shoot the problem when a "Normal" code is displayed in the diagnostic trouble code check but the problem is still occurring. Numbers in the table indicate the inspection order in which the circuits or parts should be checked. HINT: When the problem is not detected by the diagnostic system even though the problem symptom is present, it is considered that the problem is occurring outside the detection range of the diagnostic system, or that the problem is occurring in a system other than the diagnostic system. • Page Indicates the page where the flow chart for each circuit is located. • Problem Symptom • Circuit or Part Name Indicates the circuit or part which needs to be checked. MATRIX CHART OF PROBLEM SYMPTOMS When the malfunction code is not confirmed in the diagnostic trouble code check and the problem still can not be confirmed in the basic inspection, proceed to this matrix chart and troubleshoot according to the numbered order given below.
