The following was copied from here:http://www.k-bikes.com/forums/showthread.php?t=5099Canbus 101There has been a lot of discussion about the new Canbus and its implications on the usage of aftermarket equipment.The Canbus system in its fullest implementation could allow for a single communication line and a single power supply to be shared among all components. For example a turn signal could be a module, supplied with power and the data communication would tell it to turn on and off. Additionally all of these modules would not need to be fused as they would monitor current and if a short or other fault occurs, would disable the circuit until the fault was cleared. There could be a module for the headlights, horn, brake lights, etc.The implementation on our motorcycles is the same except that all control “modules” are contained in a single chassis control module called the ZFE. This ZFE has inputs from all switches and controls and outputs to all components. Each brake light switch has its own input as does each switch on the handlebar controls. Sidestand switch, clutch switch, neutral, etc are also input to the ZFE as individual inputs. Each powered component such as horn, lights, windshield, etc. has its own output from the ZFE. The ZFE has the software logic to determine what output occurs based upon one or several inputs. Each output is fault protected and most are fault tolerant as well, meaning that as soon as a fault is corrected an output will resume its normal function without the need for external intervention.
