While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruising overdrive may be prohibited temporarily under some conditions.

The cruise control ecu sends o/d cut signals to the ecm as necessary and the ecm cancels overdrive shifting until these signals are discontinued.
