Problem Symptoms Table
WARNING: This page is about a different car, the 2004 Lexus RX 330. However, it is still accessible from the selected car via links, so may be relevant.
The suspected circuits or parts for each problem symptom are shown in Fig 1 . Use this table to troubleshoot the problem when a Normal code is displayed in the diagnostic trouble code chart 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 may be that the problem is occurring outside the detection range of the diagnostic system.
