Abstract
A gear selector assembly for selecting a gear position of a transmission includes an internal mode switch having detent lever, a plurality of magnetic field sensors, a control module, a first power supply and a second power supply. The detent lever has a plurality of detents and a magnetized track, where the magnetized track includes a plurality of magnetized elements that are indicative a particular gear selector position. The magnetic field sensors are associated with each of the magnetized elements for sensing changes in a magnetic field of the magnetized track. The control module is in communication with each of the field sensors. Each of the field sensors sends an output current to the control module and the value of the output current is variable. The value of the output current is indicative of at least one of the following: the direction of the magnetic field from the corresponding magnetic track, a short circuit, and an open circuit.
