MATRIX CHART OF PROBLEM SYMPTOMS
If a normal code is displayed during the DTC check but the trouble still occurs (reappears), troubleshoot for each problem symptom, checking the
circuits for each symptom in the order given in the table.
HINT:
1. 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.
2. If the trouble still reappears even though there are no abnormalities in any of the other circuits, then check or replace the cruise control ECU as the
last step.
