Abstract

An improved method for programming a vehicle remote entry receiver includes transmitting the information over the vehicle data bus line. A diagnostic box which is typically utilized to check the electrical systems on the vehicle is provided with a switch that moves the vehicle receiver into a programming mode. Information with regard to the transmitters that are to be associated with the vehicle receiver may then be transmitted over the bus line to the receiver. Alternatively, the receiver itself may capture the transmitter signals.

Claims

1. A method of programming a receiver for a remote entry system comprising the steps of:

(1) providing a plurality of transmitters each having an individual signal, providing a receiver while said receiver is still in said programming mode; and

communicating with a communication data bus line communicating with a remote entry system, providing a diagnostic system to be selectively communicated with said bus line, said diagnostic system being provided with a switch to initiate programming mode at the receiver;

(2) connecting said diagnostic system to said bus line;

(3) actuating said switch on said diagnostic system to move said receiver into a programming mode;

(4) transmitting signals from said transmitters to be recorded to said vehicle receiver; and

(5) disconnecting said diagnostic system from said bus line.

2. A method as set forth in claim 1, wherein said remote entry system is a vehicle remote entry system and said data bus line being a communication data bus line for a vehicle.

3. A method as recited in claim 2, wherein said diagnostic system is provided with a box receiver and said transmitters transmit said signals to said box receiver, said diagnostic system then transmitting said received signals over said bus line to said vehicle receiver.

4. A method as recited in claim 3, wherein said diagnostic system transmits a signal over said bus line including a lead identifier identifying which of said transmitter signals is following said lead identifier.

5. A method as recited in claim 2, wherein said diagnostic system includes prompts to tell an operator when to record each of said plurality of transmitters at said box receiver.

6. A method as recited in claim 2, wherein said vehicle receiver receives signals directly from said transmitters and stores said received signals.

7. A method as recited in claim 6, wherein said diagnostic system sends a signal over said bus line to said vehicle receiver telling said vehicle receiver to enter a programming mode prior to said transmitters transmitting said signals to said vehicle receiver.

8. A method of programming a vehicle receiver for a remote entry system comprising the steps of:

(1) providing a vehicle receiver on a vehicle, providing a bus line communicating with said vehicle receiver;

(2) providing a signal over said bus line to said vehicle receiver telling said receiver to enter a programming mode; and

(3) transmitting a signal from a transmitter to said receiver such that said receiver is able to be programmed to an individual transmitter.

9. A method as recited in claim 8, wherein a diagnostic system includes a switch to begin actuation of said signal of step (2), said diagnostic system being selectively connected to said bus line to transmit said signal.

10. A method as recited in claim 9, wherein said diagnostic system is provided with a box receiver, said box receiver receiving said transmitter signals, and said transmitter signals then being transmitted over said bus line to said vehicle receiver.

11. A method as recited in claim 8, wherein said diagnostic system is provided with prompts, said prompts telling an operator which steps to take sequentially when programming said vehicle receiver.

12. A method as recited in claim 11, wherein a plurality of transmitters are programmed into said vehicle receiver.

13. A method as recited in claim 12, wherein said vehicle receiver is incorporated into the junction block for the vehicle, and said vehicle receiver captures and records said transmission signals after having received said signal from said diagnostic system.

14. An electronic system for programming a vehicle electrical system comprising:

(1) a programming system including outlet lines which may be selectively connected into a bus line of a vehicle; and

(2) a switch operable to begin a programming mode for a remote entry system mounted on a vehicle to be programmed by said programming system, said switch causing a signal to be sent over said bus line to a vehicle receiver to tell the vehicle receiver to enter a programming mode.

15. A diagnostic system as recited in claim 14, wherein said programming system further communicates with an antenna and a box receiver such that said antenna may capture signals from remote entry transmitters, and said box receiver may then store the signal, which may then be transmitted over said bus line to the vehicle receiver.

16. A diagnostic box as recited in claim 14, wherein said programming system is also provided with prompt lights to provide indications to an operator of proper sequential steps.

17. A receiver as recited in claim 17, wherein said line is a communication bus line.

18. A receiver for a remote entry system comprising:

a receiver body adapted to receive signals from a transmitter, and compare transmitter signals to expected signals from the transmitter based upon a transmitter code, said receiver being operable to enter a programming mode where it can be programmed with the code for an associated transmitter; and

said receiver, communicating with a remote entry system, said receiver being operable to receive a signal over a communication line to enter a programming mode, information relative to a transmitter which is to be associated with said receiver also being passed over said communication line to said receiver while said receiver is in said programming mode such that a direct connection is provided to supply the information to said receiver over said communication line.
