Symptom Related Diagnostic Procedures

MATRIX CHART OF PROBLEM SYMPTOMS








If a normal code is displayed during the diagnostic code check (sensor check) but the trouble still occurs (reappears), perform the troubleshooting for each problem symptom, checking the circuits for each symptom in the order given in the table.

HINT:
- 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 reappears even though there are no abnormalities in any of the other circuits, then check or replace the air conditioner control assembly (contains the ECU).
