O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruis-
ing overdrive may be prohibited temporarily under some condition.
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.
