This diagnostic does additional checks on the
communication bus between the control unit and the
display. In addition, the internal electronics
functionality are confirmed.
• When the connection is NG, first check for loose
terminals at the navigation unit and the display unit
connections. Next check for an open or short in the
communication line between the navigation unit and
the display unit. If you find the line has an open or
short, replace the affected shielded harness.
• If the ROM or RAM is NG, replace the display unit.
• The version represents the software version in the
display.
