Overdrive Switch: Testing and Inspection
O/D Main Switch Circuit
DESCRIPTION
The O/D main switch (transmission control switch) is a momentary type switch. When pressing the O/D main switch, the O/D OFF indicator light
illuminates and the ECM prohibits shifting into O/D. When it is pressed again, the O/D OFF indicator light goes off and the ECM allows shifting into
O/D. Turning the ignition switch OFF will reset the O/D OFF indicator light.
