ation and the AV (NAVI) control unit performs the diagnosis for each unit of system. Then, it displays the
results on the display.

At diagnosis using CONSULT-II, the AV (NAVI) control unit diagnosis function starts when the CAN com-
munication and the AV (NAVI) control unit performs the diagnosis for each unit of system.

by a technician (malfunctions that cannot be automatically judged by the system), the confirmation/
change/adjustment of setting value, the error history of system, and the communication condition of sys-
tem.
