Abstract
A method of calibrating a vehicle electrical system having a data bus includes transmitting calibration data to a calibration data device, such as a memory card, associated with an electronic device, such as a radio, simultaneous to other vehicle assembly steps; and transferring at least a portion of the calibration data from the electronic device to electronic modules coupled to the data bus upon a triggering event, such as application of electric power to the vehicle electrical system. The electronic device for transferring the calibration data includes a processor capable of being coupled to the data bus and having software capable of performing calibration procedures on the electronic modules, an interface coupled to the processor and the calibration data device and capable of receiving data from the calibration data device, and hardware and/or software for enabling the processor to transfer a portion of the data from the calibration data device through the data bus to enable the software to perform calibration procedures on the electronic modules.
