AX1–108
O–D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving with cruise control activated, in order to minimize gear shifting and provide smooth cruising
uphill, overdrive may be prohibited temporarily in some conditions.
The cruise control ECU sends OD cut signals to the ECM as necessary and the ECM cancels overdrive
shifting until these signals are disconnected.
DIAGNOSTIC CHART
Check voltage between terminals 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 (See page IN–31).
Check and replace ECM.
