Abstract

Electric control apparatus for a motor vehicle including a push button module to indicate the operator choice of transmission state, an encoder tracking the annular position of the mode select shaft of the transmission and operative to provide a transmission state signal, and a logic module receiving the operator input request from the push button module, receiving a present transmission state signal from the encoder, and operating to shift the transmission to the requested position, provide enabling of the starter motor circuit in response to receipt of a neutral or park transmission state signal from the encoder, and energize the backup lamp circuit in response to receipt of a reverse transmission state signal from the encoder.
