Unit Check (Quick Check): Display

This diagnosis does additional checks on the GA-Net bus between the audio-navigation unit and the navigation display unit. This test also checks the internal electronic functions.

• When Connection is NG, first check for loose terminals at the audio-navigation unit and the navigation display unit connections. Next check for an open or short in the communication line between the audio-navigation unit and the navigation display unit If the line has an open or short, replace the affected shielded harness.
• If ROM or RAM is NG, replace the navigation display unit.
• The version represents the software version in the display.
