Problem Symptoms Table
The suspected circuits or parts for each problem symptom are shown in the table below . Use this table to troubleshoot when, during a DTC check, a "Normal" code is displayed but the problem is still occurring. Numbers in the table show the inspection order in which the circuits or parts should be checked.
HINT:
In some cases, the problem is not detected by the diagnostic system even though a problem symptom is present. It is possible that the problem is occurring outside the detection range of the diagnostic system, or that the problem is occurring in a completely different system. SeePROBLEM SYMPTOMS TABLE on in the Cruise Control System - Diagnosis as in an example.
