Abstract

Disclosed herein is an improvement of methods and systems used to configure electronic components and modules to a vehicle. A low cost programmer tool, or key fob dongle, may manage devices coupled to a vehicle communication network. The system is designed for on-board management of multiple vehicle network protocols to support configuration of various electronic modules to a vehicle. A method for using a key fob dongle is disclosed herein. The method includes inserting the key fob dongle into an on-board diagnostic (OBD)-II connector of a vehicle, transmitting a communication detection request to the OBD-II connector, and beeping a predetermined amount of times in response to the communication detection request, wherein the beeping a predetermined amount of times identifies a vehicle communication protocol.

Claims

1. A method for using a key fob dongle, the method comprising:

inserting the key fob dongle into an on-board diagnostic (OBD)-II connector of a vehicle;

transmitting a communication detection request to the OBD-II connector; and

beeping a predetermined amount of times in response to the communication detection request;

wherein the beeping a predetermined amount of times identifies a vehicle communication protocol.

2. The method of claim 1, wherein the key fob dongle beeps three times to indicate that the vehicle communication protocol is J1850.

3. The method of claim 1, wherein the key fob dongle beeps two times to indicate that the vehicle communication protocol is single wire control area network (SWCAN).

4. The method of claim 1, wherein the key fob dongle beeps one time to indicate that the vehicle communication protocol is high speed control area network (SWCAN).

5. The method of claim 1, wherein the beeping a predetermined amount of times prompts a user to press and hold the lock and unlock buttons simultaneously of a key fob to program the key fob.

6. The method of claim 5, wherein after the user programs the key fob, the key fob dongle beeps again to confirm the key fob is programmed.

7. The method of claim 5, wherein after the user programs the key fob, a cluster in the car beeps to confirm the key fob is programmed.

8. A dongle for use in programming a key fob transmitter, the dongle comprising:

a connector to connect the dongle to an on-board diagnostic of a vehicle;

a circuit board, wherein the circuit board includes a program to read to the on-board diagnostic of the vehicle and determine what program to use for programming the key fob;

a buzzer, wherein the buzzer indicates the program of the on-board diagnostic of the vehicle and a start to user interaction, and

a light emitting diode (LED), wherein the LED is used to indicate that the programming is complete.

9. The dongle of claim 8, wherein the key fob dongle beeps three times to indicate that the vehicle communication protocol is J1850.

10. The dongle of claim 8, wherein the key fob dongle beeps two times to indicate that the vehicle communication protocol is single wire control area network (SWCAN).

11. The dongle of claim 8, wherein the key fob dongle beeps one time to indicate that the vehicle communication protocol is high speed control area network (SWCAN).

12. The dongle of claim 8, wherein the beeping a predetermined amount of times prompts a user to press and hold the lock and unlock buttons simultaneously of a key fob to program the key fob.

13. The dongle of claim 12, wherein after the user programs the key fob, the key fob dongle beeps again to confirm the key fob is programmed.

14. The dongle of claim 12, wherein after the user programs the key fob, a cluster in the car beeps to confirm the key fob is programmed.
