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 tables and proceed to the reference given for troubleshooting.
- The Matrix Table is divided into 2 chapters.
- When the circuit on which *1 is attached malfunctions, a DTC could be output.
Chapter 1: Electronic Circuit Matrix Table
Refer to SYMPTOM TABLE 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.
