PROBLEM TO BE SOLVED: To shorten inspection cycle time. SOLUTION: At least a part of data is defined as four bits, data to specify plural ports, etc., is included in one frame of instruction signals to be periodically transmitted from an on-vehicle electronic unit to a control part, a processing corresponding to the instruction signals is performed by the control part and after that, its processing result is returned to the on-vehicle electronic unit by mounting it on a response signal on the contrary to the conventional case in which all pieces of data are 8 bits. The plural ports, etc., are inspected in a cycle of periodical transmission. |
