AX2–120
OD 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 in some conditions.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels overdrive shif–
ting until these signals are discontinued.
DIAGNOSTIC CHART
Check voltage between terminal OD 1 of
ECM connector and body ground.
Check voltage between terminal OD of
cruise control ECU harness side connector
and body ground.
Check harness and connector between
cruise control ECU and ECM.
Check and replace ECM.
