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.
