System Description
NCEC0560
The malfunction information related to CVT is transferred through the line (circuit) from TCM (Transmission
Control Module) to ECM. Therefore, be sure to erase the malfunction information such as DTC not only in TCM
(Transmission Control Module) but also ECM after the CVT related repair.
