Scan Tool DataS6RW0D5104008
As the data values given in the following table are standard values estimated on the basis of values obtained from the
normally operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good
condition, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, condition in the following table that can be checked by the scan tool are those detected by TCM and output from
TCM as commands and there may be cases where the automatic transaxle or actuator is not operating (in the
condition) as indicated by the scan tool.
NOTE
The following scan tool data related to automatic transaxle can be checked only by communicating
with TCM.
