ABSTRACT:
An electronic control system for a motor vehicle of the type including an automatic transmission, a steering system having a steering column, an ignition switch having an on position and a key-in/lock position, means operative in response to movement of the ignition switch to the key-in/lock position to lock the steering column, a starter circuit, a push button shift control assembly in the vehicle passenger compartment, and a closure system requiring one or more operator steps to enter the vehicle passenger compartment. The invention control system includes means to preclude movement of the ignition switch to the key-in/lock position when the vehicle speed is in excess of a predetermined speed; means for generating a coded anti-theft signal comprising a predetermined combination of shift assembly push buttons depressed in a predetermined sequence to allow starting of the motor vehicle and to allow shifting of the motor vehicle; and means operative to display the instantaneous position of the vehicle transmission during the normal operation of the vehicle, for a predetermined period of time following removal of the ignition key from the ignition switch, and for a predetermined time following operator performance of one or more of the steps required to enter the vehicle passenger compartment.
