Abstract
Control units are mutually connected by separate common signal lines. A data link is provided between the control units via a preselected one of the common signal lines. A check is made as to whether the preselected common signal line is operating normally or abnormally. When the preselected common signal line is operating abnormally, the preselected common signal line is replaced by another common signal line in the data link.
