Abstract
A multiplex transmission system in a vehicle, for transmitting data indicating an on/off state of an ignition switch, includes first and second power distributing units receiving first and second signals over first and second signal lines, respectively, indicating the on/off state of the switch. The first power distributing unit controls a first load in accordance with the on/off state of the switch indicated by the first signal. The first power distributing unit provides a third signal to the second power distributing unit over a multiplex transmission line indicating the on/off state of the switch. When either the second signal or the third signal indicates that the switch is in an on state, the second power distributing unit controls the second load in accordance with the on state of the switch. When the second power distributing unit fails to receive the third signal, the second power distributing unit controls the second load in accordance with the on/off state indicated by the second signal.
