Automatic Transaxle System -- Problem Symptoms Table


HINT:
  1. If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check the electrical circuits for each symptom in the order given in the charts on the following pages and proceed to the page given for troubleshooting.
  2. The Matrix Chart is divided into 2 chapters.
  3. When the circuit on which mark *1 is attached is a malfunction, DTC could be output.
Chapter 1:
Refer to the table below when the trouble cause is considered to be electrical the instruction "Proceed to next circuit inspection shown on matrix chart" is given in the flow chart of each circuit, proceed to the circuit with the next highest number in the table to continue the check. If the trouble still occurs even though there are no abnormalities in any of the other circuits, check and replace the ECM.
