O/D Cancel Signal Circuit

CIRCUIT DESCRIPTION

While driving uphill with cruise control activated in order to minimize gear shifting and provide smooth cruising O/D 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 O/D shifting until these signals are discontinued.
