Problem Symptoms Table: Notes

WARNING: This page is about a different car, the 2004 Lexus GS 430. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

If a normal code is displayed during the DTC check but the trouble still occurs, check the circuits for each symptom in the order given in the charts and proceed to the appropriate procedure for troubleshooting.

The Matrix Chart is divided into 3 chapters.

If the instruction "Proceed to next circuit inspection shown on matrix chart" is given in the flow chart for each circuit, proceed to the circuit with the next highest number in the table to continue the check.
If the trouble still occurs even though there are no abnormalities in any of the other circuits, then check and replace the ECM.
