PROBLEM TO BE SOLVED: To adequately determine a trouble caused by cooperative operation of a plurality of ECUs connected to each other via an in-vehicle network, and to rapidly specify failed part. SOLUTION: A vehicle manager ECU monitors the data of each ECU on the in-vehicle network (S100), and determines the trouble (S110). In other words, a trouble related to the cooperative operation of the ECU is also determined from the data on the failure detection result by a failure detection program executed by each ECU and the data handled between the ECUs via the vehicle manager ECU. An inspection diagnosis program ready for the trouble is acquired from a customer server (S160), the corresponding processing is performed by the applicable ECU by executing the acquired inspection diagnosis program, and the failed part is specified by transmitting internal variables in the specified control, etc., (S170). |
