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.
