Overdrive Indicator Lamp: Testing and Inspection

CIRCUIT DESCRIPTION

The O/D main switch is a momentary type switch. When the 0/D main switch is pressed, the O/D OFF indicator light lights up and the ECM prohibits the gear from shifting to the O/D. And, when the O/D main switch is pressed again, the O/D OFF indicator light goes off and the ECM allows the gear to shift to the O/D. Turning the ignition switch OFF will reset the O/D OFF indicator light.
