ADDITIONAL SERVICE WHEN REPLACING CONTROL VALVE OR TRANSAXLE ASSEMBLY


Description

Perform the following work after the transaxle assembly/control valve is replaced.

ERASING THE CALIBRATION DATA
- The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the
ROM assembly (in the control valve). This enables the TCM to perform accurate control. For this reason, after the transaxle assembly/control valve is replaced, it is necessary to erase the calibration data that is stored in the TCM and load new calibration data.

ERASING CVT FLUID DEGRADATION LEVEL DATA
- TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if the transaxle assembly/control valve is replaced, it is necessary to erase the CVT fluid degradation level data recorded by TCM.
