PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check
the electrical circuits for each symptom in the order given in the charts on the following pages and proceed
to the page given for troubleshooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On-vehicle Repair Matrix Chart
Chapter 3: Off-vehicle Repair Matrix Chart
If the instruction ºProceed to next circuit inspection shown on matrix chartº 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.
