1. A system for use in selectively operating components of a vehicle, said system comprising:
- an apparatus remote from the vehicle, said apparatus includingan input means for providing signals indicative of a desired operational state of the vehicle components;
a digital controller for generating command signals from said input signals and for generating, from decoded component status signals, signals indicative of the operational state of the vehicle components;
a transmitter means receiving said command signals for encoding and providing radio frequency transmission thereof;
a receiver means for receiving and decoding said encoded status signals;
a means for displaying said engine and accessory operational state signals; and
an apparatus affixed to the vehicle, said apparatus includinga receiver means for receiving and decoding said digitally encoded command signals;
a means configured with the vehicle components for providing signals indicative of the operational state thereof;
a digital controller for generating component status signals from said operational state signals, said controller further for providing component control signals in dependence on said received command signals;
a transmitter means receiving said component status signals, for encoding and providing radio frequency transmission thereof; and
a means for operating the vehicle'"'"'s components in dependence on said control signals;
said vehicle digital controller, during a first time period, further not responding to command signals subsequent to a first received command signal until the expiration of said first time period unless said operational state signal generation means provides signals corresponding to said desired vehicle operational state.

Abstract
A novel system for use in remotely starting a motor vehicle and operating vehicle accessories includes a remote unit having a digital controller which provides encoded digital command signals and a vehicle unit which receives the digital command signals and controllably operates the vehicle'"'"'s engine and accessories in dependence thereon. The system is characterized by a frequency shift keying method of signal transmission which is highly reliable and not burdened by known carrier on, carrier off techniques.
