Abstract
A remote control system for a vehicle includes a controller for learning a unique code of a remote transmitter to define a learned remote transmitter capable of causing performance of a function associated with the vehicle, for example. The controller performs remote transmitter verification to generate an indication relating to whether a new uniquely coded remote transmitter has been learned by the controller. The remote control system is advantageously used, in one embodiment, for a vehicle security system. Transmitter verification may also be incorporated in a remote keyless entry system, remote engine starting system, and a door access system, for example. In one embodiment, the remote transmitter verification is based upon the controller being recently entered into the remote transmitter learning mode. According to another embodiment, the remote transmitter verification is based upon a number of learned remote transmitters, a change in that number, or a change in a learned code of a remote transmitter. The indication may be provided at the vehicle or remote therefrom by any of a light, a visual display, a vibration transducer, a speech message generator, and an audible signal …
