•  The TCM determines if there is a cold condition based on the engine coolant temperature signal received from the PCM.

•  If a cold condition is determined, the TCM sets the minimum engine speed higher. As a result, warming of the CVT is promoted by setting the minimum engine speed higher than normal.

•  The TCM determines if there is an excessive rise in oil temperature based on the CVT fluid temperature and the engine coolant temperature signal received from the PCM.

•  If it is determined that the oil temperature and water temperature have risen excessively, the TCM regulates the maximum engine rotation speed. As a result, overheating of the CVT is prevented by setting the engine speed lower than normal.
