O/D Cancel Signal Switch Circuit
CIRCUIT DESCRIPTIONWhile driving with cruise control activated, in order to minimize gear shifting and provide smooth cruising when driving uphill, overdrive may be prohibited temporarily in some conditions. The cruise control ECU sends O/D cut signals to the Engine Control Module (ECM) as necessary and the ECM cancels overdrive shifting until these signals are discontinued. (For details, see the cruise control system).
