O/D Main Switch & O/D OFF Indicator Light Circuit
CIRCUIT DESCRIPTION
The O/D main switch contacts go off when the switch is pushed in and come on when it is pushed out. In O/D main switch OFF position, the O/D OFF
indicator lights up, and the ECM prohibits shifting to overdrive. The ECM also causes the O/D OFF indicator light to blink when a malfunction is
detected. In this case, connecting the OBD-II scan tool or TOYOTA hand-held tester to the DLC3 can display the diagnostic trouble code.
