When the decider 104 decides that the connection is wrong as above (NO at step S3), the controller 100 causes the display device 473 to display a message to the effect that the connection is wrong, as shown in FIG. 9B (step S6). For example, the controller 100 causes the display device 473 to display a warning message AM1 as “Wrong Connection” as shown in FIG. 9B, to announce that the connection is wrong.
Further, the controller 100 causes the display device 473 to display the detail of the reconnection work (step S7), according to the work to be done stored in the column of “Work Type” shown in FIG. 9A. More specifically, the controller 100 causes the display device 473 to display a work suggestion message AM2 as “Transfer Connector (C) on Connector Receiver (M) to Connector Receiver (C)”, and a work suggestion message AM3 as “Transfer Connector (M) on Connector Receiver (C) to Connector Receiver (M)”, as the work suggestion indicating the correct counterpart for the connector JF decided to be wrongly connected, and a work suggestion message AM4 as “Fasten Connector (Bk) More Securely” indicating the correct connection method of the connector JF4.
When the modified cross-reference table TB shown in FIG. 5B is employed, the decision results that the connection is wrong are stored in the modified pattern, as shown in FIG. 9C, are stored.
After step S7, the operation of the controller 100 returns to step S2.
