WRITING TCM DATA

TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this reason, after replacing control valve, it is necessary to write new data.

ERASING OF CVT FLUID DEGRADATION LEVEL DATA

TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if the control valve is replaced, it is necessary to erase the CVT fluid degradation level data recorded by TCM.
