O/D Cancel Signal Circuit

CIRCUIT DESCRIPTION
While driving with cruise control activated, in order to minimize gear shifting and provide smooth cruising on an uphill overdrive may be prohibited temporarily in 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.
