Abstract: A shift system includes a shifter including a first switch, a second switch, and an interlock switch and being operable between a plurality of gear states. A controller is communicatively coupled with the shifter to receive signals that correspond to each of the first switch, the second switch, and the interlock switch. The controller includes a diagnostic counter that includes a passing criteria and a predetermined diagnostic threshold and is configured to adjust the diagnostic counter based on at least one of the signals received from the shifter being inconsistent with the others of the signals received.
