Abstract
A vehicle communication control apparatus serves to distribute purposes of trouble diagnosis of vehicle electronic appliances in a group of networks, thereby enhancing an efficiency of trouble diagnosis and reducing a time required for the trouble diagnosis. A plurality of groups of networks to each of which vehicle electronic appliances (4, 5, 6) are connected are interconnected by first, second and third vehicle communication control apparatuses (10, 20, 30). The first, second, and third apparatuses (10, 20, 30) are provided with means for diagnosing a trouble of a vehicle electronic appliance (5 or 6) in one group of networks in response to a trouble diagnosis start command from a trouble diagnosis tester (8) for another vehicle electronic appliance (4) in the other group of networks and with means for storing results of trouble diagnosis concerning each vehicle electronic appliance (5 or 6) and for transmitting the results to the trouble diagnosis tester (8) in good time. It is possible to enhance an efficiency of each network since each network operates individualy during the trouble diagnosis.
