ABSTRACT:
In a controller for a vehicle-mounted component, a shift position detector that detects an effective shift position of an automatic transmission. A shift position switching unit switches the effective shift position of the automatic transmission. A parking switching unit mechanically locks the output shaft of the automatic transmission when the effective shift position in a parking position. A shift position switching controller, which is not energized when the engine is stopped, controls the shift position switching unit. A memory device memorizes the effective shift position at a timing when the shift position switching controller stops being energized. A vehicle-mounted component controller prohibits an operation of a vehicle-mounted component when the effective shift position in the memory device is not in the parking position while the current supply to the shift position switching controller is stopped.
