Key fob dongle
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.
1. 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.
2. The dongle of claim 1 , wherein the key fob dongle beeps three times to indicate that the vehicle communication protocol is J1850.
3. The dongle 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 dongle of claim 1 , wherein the key fob dongle beeps one time to indicate that the vehicle communication protocol is high speed control area network (HSCAN).
5. The dongle 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 dongle 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 dongle of claim 5 , wherein after the user programs the key fob, a cluster in the car beeps to confirm the key fob is programmed.
