Unit Check: Display

This performs additional checks on the communication bus between the control unit and the display. In addition, the internal electronics and touch screen functionality are confirmed.

• When the connection is NG, first check for loose terminals at the navigation unit and the navigation display connections. Next check for an open or short in the communication line between the navigation unit and the navigation display. If the line is found to have an open or short, replace the affected shielded harness.
• If the ROM or RAM is NG, replace the navigation display.
• The version represents the software version in the display.
• Six CD connection checks the status of the connection between the CD changer and the audio unit. An NG represents an open in that circuit.
• Display Lid indicates if the front display panel is Open or Closed. This should always say, "Closed".
