1. A system for selecting a transmission range in a vehicle, comprising:

  • a plurality of range selection buttons configured to individually select corresponding ones of a plurality of ranges;

    a plurality of sensing circuits configured to generate sense signals based on positions of corresponding ones of the plurality of range selection buttons;

    a park range selection button configured to select a park range;

    a park sensing circuit configured to generate sense signals based on a position of the park range selection button;

    a button state module configured to output state signals corresponding to the plurality of range selection buttons based on the sense signals from the plurality of sensing circuits; and

    a control module configured to select a range based on the sense signals from the park sensing circuit and the state signals from the button state module,wherein the control module selectively identifies a park button fault based on the sense signals from the park sensing circuit and sets the transmission range to a park range when the park button fault occurs and none of the plurality of range selection buttons are activated.
