ABSTRACT:
A system and method applicable to a vehicle for communicating between data processing stations are disclosed in which successive initializing commands (INIT) are transmitted by a master station performed by a diagnostic device to all subordinate electronic control units, which are data processing stations, at a predetermined time interval. The number of INIT commands transmitted corresponds to the number of information signals transmitted to a selected control unit after a control command to the selected control unit is executed. For example, in a case where two information signals are transmitted, the two successive initializing commands are transmitted to each control unit. In this case, the command code transmitted from the master station prior to the information signals is different from a system call command code even if both of the information signals have the same information as the initializing commands. Therefore, no erroneous response to the information signals by a non-selected control unit occurs.
