Problem Symptoms Table
HINT:
- If a normal code is displayed during the DTC check although the trouble still occurs, check the electrical circuits for each symptom in the order given in the following charts and proceed to service information given for troubleshooting.
- The Matrix Chart is divided into 2 chapters.
- When the circuit on which* 1 is attached malfunctions, a DTC could be output.
Refer to the table below when the trouble cause is considered to be electrical. If the trouble still occurs even though there are no abnormalities in any of the other circuits, then check and replace the ECM.
