PURPOSE:To generate a simulated fault without any problem even if an electronic equipment is connected to the other one connected with a bus network by means of a signal line except for the bus network. CONSTITUTION:At the time of simulating the fault by providing a second data bus 23 in addition to a first data bus 19 connecting the electronic equipment A and a bus controller 2, relay boxes 24 and 25 switch the electronic unit A from the first data bus 19 to the second data bus 23 so as to connect them. A simulation device 26 executes a fault response to the bus controller 2 in place of the electronic equipment A. The simulation device 26 gives data to the electronic equipment A by using the second data bus 23 in place of the bus controller 2 as necessary so as to prevent thoccurrence of abnormality in a low-rank connected equipment C connected with a signal line 11. |
