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 below. Then proceed to the appropriate Non-Trouble Code Chart or component test.
When troubleshooting, check Chart 1 first. If instructions are given in Chart 1 to proceed to Chart 2 or 3, proceed as instructed.
1. If the instruction "Proceed to next circuit inspection shown on matrix chart" is given in the flowchart for each circuit, proceed to the circuit with the next highest number in the table to continue the check.
2. If the trouble still occurs even though there are no abnormalities in any of the other circuits, then check and replace the ECM.
