Abstract
A remote keyless entry apparatus is disclosed for use with a vehicle. The apparatus includes a receiving unit disposed within the vehicle and a key fob transmitter for transmitting a plurality of signals to the receiving unit. The transmitter includes a transmitting unit for transmitting the plurality of signals to the receiving unit, a control unit operatively connected to the transmitting unit for controlling transmission of the plurality of signals and a diagnostic gathering and storage unit electrically connected to the control unit for supplying diagnostic data to the control unit. Additionally, the transmitter includes a key fob unit selectively connected to the control unit and to the diagnostic unit. The arrangement is such that in a first operative disposition of the key fob unit, the key fob triggers the control unit so that a first signal of the plurality of signals is generated by the transmitter unit for reception by the receiving unit. In a second operative disposition of the key fob, the key fob triggers the diagnostic unit so that a second signal of the plurality of signals is generated by the transmitting unit for reception by the receiving unit. The second signal containing diagnostic information pertaining to the key fob, the receiving unit provides a diagnostic report after reception of the second signal.
